How to Size Your Battery Fuse to Inverter Cleversolarpower by Nick 2025-10-31 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comMEGA Fuses: amzn.to/3LhroKfClass-T Fuse: amzn.to/47iL9d5MRBF Fuse: amzn.to/3Je78ZrANL Fuse: amzn.to/49tf8jGNH00 Fuse: amzn.to/4qx0uydAliexpress 200°C cables: cleversolarpower.com/go/aliexpress200Windynation 105°C cables: amzn.to/3YgWzcf Most people size their main battery fuse completely wrong. You’ll hear advice like “200Ah battery needs a 200A fuse,” or “match the fuse to the battery BMS.” That’s dangerous. In this video I’ll show you the correct way to size your battery fuse so you don’t melt a cable or burn your system down.We’re going to walk through a simple step-by-step method to choose the correct fuse size. First we figure out how much current your system can actually pull from the battery. Usually that’s the inverter, not the amp-hour rating of the battery. Then we add a safety margin, pick the next fuse size up, and size the cable so it can safely carry that fuse without overheating. I’ll do an example with a 12V LiFePO₄ battery and a 2000W inverter so you can see the math and the final fuse value.After that, we’ll talk about something almost nobody mentions: voltage rating and interrupt rating. A fuse that’s fine on a 12V or 24V system can be completely unsafe on a 48V lithium bank, because a “48V” battery actually charges up to around 58V. I’ll show you which common fuse styles (ANL, MEGA, MRBF, Class T, etc.) are safe for 12/24V and which ones you should be using for serious 48V systems. We’ll also talk about interrupt rating: how much short-circuit current the fuse can actually stop in a dead short. This is critical with lithium because a short can easily dump thousands of amps instantly.We’ll also look at breakers. Yes, you can use a breaker instead of a fuse in some systems, but it has to be DC rated for the correct voltage and it has to be able to interrupt that fault current. I’ll show you what’s acceptable, what’s just marketing, and what I would never install on a 48V battery bank.I’ll give you a reference chart for fuse sizing based on inverter size at 12V, 24V, and 48V. I also give you a chart where i recommend the fuse sizes per inverter at different voltages.
How to Balance a (New) LiFePO4 Battery - 3 Methods Cleversolarpower by Nick 2026-04-21 | Bench power supply for 12 and 24V batteries: amzn.to/3ORBV0PBench power supply for 48V batteries: amzn.to/4dZFMmQ 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIf your LiFePO4 battery never seems to finish charging or the voltage cuts off earlier than expected, you most likely have a cell imbalance. In this video I explain how to tell if your battery is balanced, what the numbers actually mean, and when you even need to do anything about it.I cover three methods for balancing: using a standard charger, using an MPPT with a solar panel, and using a bench power supply. Each method has its own advantages and limitations, and I walk through the exact steps for each one including how to approach it if your battery has a Bluetooth BMS versus a dumb BMS with no app.The good news is that most batteries do not need manual balancing right out of the box. LiFePO4 cells should matched at the factory and the BMS handles small drifts over time. But if you have a battery with a low balancing current and a high balance start voltage, the BMS may not be able to keep up on its own, and that is where these methods come in.

I also test it on a microwave, kettle, fridge, and 2000W heater to see what it can actually handle in a real off grid setup.Before you buy this inverter, there are a few things worth knowing, including a cable issue and a limitation with the UPS function that Renogy doesn't make obvious. I explain all of it, including what size battery you need to run this safely on 12V.The US version of this inverter includes a built-in GFCI. If you're on the EU version, you'll need to wire one in yourself. I cover that too.
Forget Cycle Count. This Is What Actually Kills Your Battery Cleversolarpower by Nick 2026-03-30 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comEveryone buying a lithium iron phosphate battery looks at the same number: cycle life. 3,000 cycles. 6,000 cycles. 15,000 cycles. But in this video I'm going to show you why that number is almost irrelevant for most people, and what actually determines how long your battery lasts.I have two real cells with factory capacity tests printed right on them. A 280Ah cell that has been sitting in storage for three and a half years, and a 100Ah EVE cell from a Vatrer battery pack that is 15 months old. I tested both with a DL24 capacity tester and compared the results against the factory numbers. The results tell a very clear story about calendar aging. The degradation that happens to your battery whether you use it or not.I also cover what is actually happening inside the cell on the whiteboard. The SEI and CEI layers that form over time, why heat and high state of charge speed up the process, and why storing at 0% is just as bad as storing at 100%. I then introduce a new way to think about battery longevity not in cycles, but in years. Based on these real world tests, a well stored LiFePO4 cell should take approximately 14 years to reach 80% of its original capacity. That is the number that matters for solar, off grid, and backup power users.The video also covers the difference between cell health and pack health, why you still need to charge to 100% periodically for BMS balancing, how C-rate and heat during daily use affect aging, and why BMS quality matters just as much as cell quality and possibly more.Naumann et al. 2018 — Analysis and modeling of calendar aging of a commercial LiFePO4/graphite cellsciencedirect.com/science/article/abs/pii/S2352152X18300665ACS Applied Energy Materials 2025 — Deciphering the Calendar Aging Degradation Mechanism of LiFePO4-Graphite Pouch Cellspubs.acs.org/doi/10.1021/acsaem.4c02761Vachenauer et al. 2025 — Shelf life of lithium-ion batteries: Recommissioning LiFePO4/C cells after ten years of uninterrupted calendar agingsciencedirect.com/science/article/pii/S0378775325016155Applied Sciences 2025 — Study on Influencing Factors of Calendar Aging and Cycle Aging of LFP Batteriesmdpi.com/2076-3417/15/23/12749

I also cover grounding requirements for all metal components and how I added a transparent plastic safety cover using standoffs and a threaded rod mounted into the backboard.At the end I do a full price comparison between the DIY build and the Victron Lynx setup — $82 versus $630. I also show the complete system installed in my garage. If you want a dedicated video on ESS systems like this one, let me know in the comments.The busbar is pure copper.

Humsienk 12V 100Ah Review: Why It Is Overheating Cleversolarpower by Nick 2026-03-10 | Link to the battery: amzn.to/4bi7PLhTheir website: cleversolarpower.com/go/humsienk12v100ah coupon code: 'NICK' for 5% offEU: cleversolarpower.com/go/EUhumsienk12v100ah coupon code: 'NICK' for 5% offAliexpress shipped from US: cleversolarpower.com/go/aliexpressUS📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this review, I test the Humsienk 12V 100Ah battery under high current and with a thermal camera to see how it really performs.

Ecoworthy 12V 100Ah Review and Teardown Cleversolarpower by Nick 2026-03-08 | Link to the battery (V2): amzn.to/4rgI2c0 Better alternative: amzn.to/4riQyHI📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I test an Eco-Worthy 12V 100Ah LiFePO₄ battery to see if it’s a solid mid-range option or not. I start with the basics: unboxing, a 0.2C capacity test, and a charge/discharge efficiency check. Right away the numbers didn’t look great, and the battery also kept hitting overvoltage protection before it could reach a normal full charge voltage, which pointed to a balancing problem.After the normal tests, I try to use the Bluetooth app to check individual cell voltages, but the battery won’t connect at all. At that point the only way forward is opening the case to measure what’s going on inside. I find a large cell voltage spread near the top and a very low passive balancing current, which explains why the pack can’t recover from imbalance in any reasonable amount of time.To quantify the imbalance, I compare the state of charge of the highest and lowest cell group using capacity testers and show how many amp-hours they’re apart, then I calculate how long the balancer would need to correct it. In the end I explain why I can’t recommend this unit as-tested: not enough usable capacity out of the box, repeated charge cutoff from imbalance, and a battery management system that isn’t doing enough to fix it.Important note: after recording, Eco-Worthy told me the battery I received was their older version and that the newer version was not available from the EU warehouse at the time. They also confirmed this older version does not have Bluetooth, even though I requested the Bluetooth model and the listings can look identical to buyers. Because this version is still being shipped from warehouse stock, I’m publishing the results as they are. If I receive the latest version, I’ll run the same tests and post the results as well.Review policy: cleversolarpower.com/batteryreview
Why Some Batteries Never Finish Charging - And How to Fix it Cleversolarpower by Nick 2026-03-03 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIf I only showed you a capacity test, you’d probably think both of these batteries are fine. I tested the Vatrer and Dyness batteries side by side for a week, and the real difference only showed up once I introduced a small cell imbalance. One pack can recover from drift fast enough to behave normally over time, while the other one struggles.In this video I’ll walk you through how I checked cell matching, why cells drift over time even when the matching looks good, and what passive balancing is actually doing inside the BMS. I’ll explain why balance start voltage and balancing current matter in a real solar charging setup, then I’ll run a simple 0.5Ah imbalance test to see how quickly each battery can “catch up.”I’ll also show you how to spot imbalance symptoms without Bluetooth by looking at your charge curve, and why a hard cutoff near the top can create short voltage spikes that aren’t ideal in a system. If you’ve ever had a battery that won’t finish charging or seems to stop early near full, this will make the whole thing click.
12V Can Be A Costly Mistake Cleversolarpower by Nick 2026-02-25 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I answer a question I get all the time: when should you increase your battery voltage from 12V to 24V or 48V? The simplest rule I can give you is this: once your system starts pulling more than about 200 amps on the DC side, you’re entering the zone where builds get expensive and inefficient.I’ll walk through a real example using a 3000W inverter on a 12V battery. The DC current ends up around 278A, and after applying a safety factor you’re suddenly sizing for a 350A fuse and very large cable like 4/0 (120 mm²). The copper gets bulky and expensive, the hardware gets bigger, and losses through heat start stacking up.Then I show the same inverter power on 24V so you can see why increasing voltage usually fixes the problem immediately: current halves, fuse size drops, cable size becomes manageable, and the system becomes cheaper and more efficient. I also explain why this isn’t just about cable cost — high current increases heat loss because power loss rises with I²R, and those losses happen not only in the wire but in every lug, fuse, breaker, busbar, and disconnect in the system.Finally, I cover the practical side: why higher voltage can make charge controllers cheaper for the same solar power, why common DIY components often top out at 250A, and when higher voltage isn’t automatically the best choice, especially in vans and RVs where alternator charging and solar array voltage constraints can make 24V the sweet spot.If you’re planning an off-grid build and you want it reliable, affordable, and clean, use the 200A rule as a sanity check. Check the recommended inverter-size table in the video and choose the voltage that keeps your DC current under control.

DIY 16kWh Battery Box vs 3× 48V 100Ah Batteries Cleversolarpower by Nick 2026-02-12 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified48V 100Ah Battery: cleversolarpower.com/go/wattcycle48v100ah or amzn.to/4aeXjVQ 🎁 Free Diagrams: cleversolarpower.comIn this video I’m comparing two popular ways to build a roughly 15–16 kWh 48V LiFePO₄ bank: a big DIY battery box kit and three separate 51.2V 100Ah rack-style often called golf cart batteries in parallel. DIY boxes look like the obvious winner on price, but once you factor in the real-world install parts and the day-to-day practical differences, the answer isn’t always as simple as people think.First I break down the raw capacity numbers and show the math for total kWh in each setup. Then I go through the real costs, including the add-ons you actually need when you parallel batteries, like fusing and battery cables. I also calculate the cost per kWh for each option so you can see exactly what you’re paying for usable storage, not just the price of the battery.After the numbers, I talk about the things that matter in the real world: how easy each system is to install, how modular it is if you want to start small and add capacity later, what happens if a battery shuts down, and the risks and responsibilities that come with DIY assembly at 50+ volts DC. By the end you’ll know which route makes the most sense depending on whether you prioritize the lowest possible $/kWh, simplicity, serviceability, or long-term peace of mind.
Should You Ground Solar Panels? Cleversolarpower by Nick 2026-02-05 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I’m going to show you how to ground solar panels the right way, and why it matters more than most people think. A lot of people hear the word “grounding” and immediately think lightning. Lightning is part of the bigger picture, but the most common safety issue is much simpler: if a fault happens and the metal frames or racking become energized, you can get shocked while working on a roof and that shock can make you lose your balance and fall.I’ll walk you through the difference between bonding and grounding/earthing, because those two terms get mixed up all the time, even by me. Then I’ll show you what actually needs to be bonded on a typical solar array so all the metal stays at the same potential. We’ll also talk about why “floating” metal can sometimes show stray or induced voltage when you measure it, and why that’s still something you want to take seriously on a roof. After that, I’ll explain whether you need a separate ground rod near the panels (and why a “separate earth” can cause problems if it isn’t bonded back properly). Finally, I’ll cover the basics of grounding wire size for Europe versus the U.S., what a standard ground rod looks like in the U.S., when you add a second rod, and the typical spacing.Quick safety note: electrical rules vary by country and even by state, so always follow your local code and the instructions from your racking and equipment manufacturers.

In this updated guide, I'll show you when to use series, when to use parallel, and most importantly—the actual cost difference between different wiring methods.What you'll learn:- Series vs parallel basics (voltage vs current)- Why I default to series wiring for most installations- How hybrid inverter voltage limits (145V vs 500V) affect your design- The truth about shading and bypass diodes- Real cost comparison: branch connectors vs combiner box vs dual MPPTs- When parallel wiring actually makes sense- How to properly fuse parallel strings (and why it matters)Cost breakdown comparison:Option 1: MC4 branch connectors (not recommended) - $234Option 2: Proper combiner box setup - $250Option 3: Two MPPTs for redundancy - $277The combiner box only costs $16 more than the risky branch connector setup, and it's way safer. I'll show you exactly why.Key takeaway: Start with series wiring, and only add parallel or multiple charge controllers when you have a clear reason to do so.Useful links:How to calculate series string length: youtu.be/5xKyWYo9zJkVideo on fusing parallel solar panels: youtu.be/aXPbbhd9R_kVideo on shading: youtu.be/hhTgGrEDCaM

The goal is to show a practical layout that can charge from three sources—solar on the roof, the alternator while driving through a DC-DC charger, and shore power when you plug in at a campground. I explain how each charging source connects into the system and why 24V is a good middle ground for an RV compared to 12V and 48V.For the solar side, I use three 200W panels and show how to check panel voltage against the charge controller’s maximum input, including a cold-weather safety factor so you don’t accidentally exceed the MPPT rating. I also show how to estimate realistic charging current into a 24V battery bank and how that influences charge controller sizing. From there, I cover the purpose of a PV disconnect and when you do—or don’t—need string fuses.For alternator charging, I explain why a DC-DC charger is used instead of connecting lithium batteries directly to the alternator, and how a 12V starting system can charge a 24V house bank safely. On the shore power side, I explain what an inverter/charger does, roughly how much charging power a 70A charger provides at 24V, and how the same unit can power AC loads from shore power when you’re plugged in. I also mention how generator charging fits in through a transfer switch.In the battery section, I show a simple 24V battery bank using two 24V 100Ah batteries in parallel for about 5kWh of storage, and I explain the wiring approach using MRBF fuses at each battery, a main DC breaker as the primary disconnect, and a busbar to keep connections safe and organized. I also cover why some inverter specs are listed in VA instead of watts, what that means in practice, and what a 3000W-class inverter can realistically run in an RV.Because most RV accessories are still 12V, I include a 24V-to-12V converter feeding a dedicated 12V fuse box for lights, pumps, fans, and other 12V loads. I then go through the wire and fuse sizing step by step for the major circuits: PV wiring, MPPT output wiring, inverter cables and main fuse, individual battery cables and fuses, DC-DC charger input/output wiring, and the 24V-to-12V converter wiring. The focus is on how to calculate currents, apply safety margins, and pick standard fuse sizes and wire gauges.Finally, I show how to place a GFCI breaker on the inverter’s output, how to size it for 120V versus 230V setups, and how grounding is handled in a mobile system. I explain the difference between AC grounding and DC grounding, where grounds should land, and why adding extra neutral-to-ground bonds in the wrong place can cause nuisance tripping.
DC to DC Charger Wire and Fuse Calculator Cleversolarpower by Nick 2025-12-18 | Link to the calculator: cleversolarpower.com/dc-to-dc-charger-wire-and-fuse-calculator📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I explain how my DC-DC charger wire and fuse calculator works, and why I built it in the first place. I kept getting the same questions about wire gauge, fuse size, voltage drop, and “will my battery still charge to 100%?”—so this calculator puts the math in one place and makes the decision process simple.You’ll see the calculator on screen and I’ll walk through exactly what each input means, what the calculator is calculating in the background, and how to interpret the results. The goal is to help you size wiring that’s safe, avoids overheating, and doesn’t rely on guesswork.Then I go through two real examples step-by-step: a 12V to 12V 30A DC-DC charger setup, and a 12V to 24V 15A DC-DC charger setup. I explain how the wire run length affects voltage drop, why the recommended wire size changes with distance, and how the fuse selection ties back to protecting the cable.I also address a common worry with long wire runs: “If I lose voltage in the cable, won’t the battery never reach the target charging voltage?” I explain why that’s not how charging works in practice—voltage drop is highest at full current, but as the battery fills up the current naturally tapers down, the voltage drop becomes much smaller, and the battery can still reach full charge.
Overpaneling Solar: How Much Is Too Much? Cleversolarpower by Nick 2025-12-11 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I explain why it’s often completely fine, and even smart to connect more solar panels to your charge controller or string inverter than the spec sheet suggests. This is called overpaneling. I’ll show you how this is used in grid-tied systems, like in Belgium where tax is based on string inverter size, and how you can apply the same idea in off-grid systems with an MPPT or hybrid inverter to get more energy without buying oversized electronics.You’ll learn the two hard limits you must always respect: maximum PV input voltage and maximum PV input current. I walk through the simple Voc × 1.25 rule for deciding how many panels you can put in series, and how to use Isc with a safety factor to size the parallel side correctly. Once those are under control, you’ll see why a bit of extra panel wattage does not “blow up” your controller. It causes harmless clipping on the best days.I also go through a practical example with a Victron SmartSolar 100/30 and six Eco-Worthy 100 W panels in a 3S2P configuration, so you can see exactly what happens on the PV side versus the battery side. You’ll see how much power the array can realistically produce, how much the MPPT will actually deliver to the battery, and why this is classic, safe overpaneling.Finally, I cover when overpaneling stops making sense: RVs and boats with limited roof space, low-voltage MPPTs that force you into lots of parallel strings, the need for combiner boxes once you exceed MC4 connector ratings, and local regulations that may limit the panel-to-inverter ratio on grid-tied systems.
Solar Panel to Charge Controller Cable Size Cleversolarpower by Nick 2025-12-04 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comLink to the voltage drop calculator: calculator.net/voltage-drop-calculator.html In this video I correct a mistake I made in a previous solar wiring video and in my book. I walk you through the proper way to size the PV cable between your solar panels and the MPPT charge controller, focusing on the difference between using Isc × 1.56 and Isc × 1.25. You’ll see how this impacts the voltage drop calculation, the final PV wire size, and how much you actually spend on copper in your off grid solar system.I use a real example with two 200W solar panels in series to show you step by step how to work out the string voltage, the cable ampacity and the acceptable voltage drop. We compare the old method, where I used Isc × 1.56 for everything, with the corrected method, where we still use Isc × 1.56 for ampacity but only Isc × 1.25 for the solar voltage drop calculation. This simple change can let you go from 8 AWG to 10 AWG on the PV run, while staying completely safe and within the current ratings of the cable.I’ll also talk about why the PV-to-MPPT cable is usually the longest and most critical run in an off grid solar setup, why high DC voltage can be dangerous if you wire panels in series, and a simple safety sequence to follow when connecting your solar panels, PV disconnect and battery. If you’re interested in topics like PV cable sizing, solar wire size, MPPT charge controller wiring, off grid solar design and voltage drop calculation, this video will help you clean up your method and save some money on your next installation.

I’ll show you how to estimate daily energy use (including a fridge with a sensible duty cycle), turn your chosen days of autonomy into a clear energy target, pick the right system voltage so the inverter current stays reasonable, and convert that target into a practical battery capacity. We’ll also cover when to use a 24 to 12V converter for 12V DC loads on a 24V system.You’ll see how to size the solar array to recharge the battery in a single good-sun day using PVWatts, translate that into a panel count, and select an MPPT. I’ll walk through checking controller voltage limits with a cold-weather Voc margin, choosing wire gauges to keep voltage drop under control on longer runs, and laying out a simple, reliable wiring path from panels to AC.Finally, I’ll teach the protection strategy that keeps systems safe and serviceable: MRBF fuses on each battery, a main DC breaker, a PV disconnect.
Gobelpower Factory Visit in China Cleversolarpower by Nick 2025-11-17 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comI visited the Gobelpower factory in Dongguan China. I recently tested a DIY Gobelpower 16kWh battery. I was still in touch with them while I was visiting an expo in Shanghai. They invited me to come over and take a look at their factory. So I said yes and they agreed I recorded their Factory. Some of the footage has been removed, so I didn't show how the factory looks completely because they wanted some parts to be kept a secret, which is to be expected.
4×12V vs 1×48V: The REAL Cost Cleversolarpower by Nick 2025-11-03 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified4x 12V 100Ah LiFePO₄ battery: amzn.to/4oSLQj3(Pre-order) Wattcycle server rack battery: cleversolarpower.com/go/wattserver48V 100Ah Golf Cart Battery: amzn.to/43b0VEpBalancer: amzn.to/4olIHsl4 AWG / 25 mm² with lugs: cleversolarpower.com/go/aliexpress200MRBF terminal fuse: amzn.to/3Je78ZrWhich is actually cheaper for a 48-volt system: four separate 12V 100Ah batteries wired in series, a 48V 100Ah server-rack battery, or a 48V 100Ah gold cart battery? In this video I break down the real costs most people ignore—balancers, jumpers, breakers/fuses, and the extra time it takes to make a four-battery stack behave. I’ll show you why the “cheap” option isn’t so cheap once you include the hidden cost, and why a simple 48V golf cart battery with an MRBF fuse on the post is usually the best value for a reliable 5 kWh bank.I start with the four-by-12V series build everyone recommends, add the external balancer(s), size the interconnects to the BMS limit and inverter surge, and total up the parts. Then I compare that to a 48V rack battery (breaker and comms included) and finally to a standard 48V 100Ah battery in a plastic case—no communication, just one battery with one BMS that works. If you already own a couple of 12V batteries and you’re upgrading, I also explain when adding one or two more can make short-term financial sense, and what the trade-offs are long-term.
Producing Solar Panels in China: How a Solar Panel is Made at Sunwaytech Cleversolarpower by Nick 2025-10-23 | In this video I visited a solar panel factory located in Nantong, China. This factory is from the company sunwaytech. This video is not sponsored.I asked the company if I could come over and make a video on how solar panels are made and they approved. So after a tour in the factory where they explained everything to me I took my camera and recorded the whole process. This gives a unique look into how solar panels are manufactured from start to finish. something I wanted to see for a long time.
Gobelpower 15kWh DIY Battery Kit Assembly and Review GP-SR1 Cleversolarpower by Nick 2025-10-16 | Link to the battery kit: cleversolarpower.com/go-SR1In this video, I’m reviewing the GobelPower GP-SR1-Kit, a DIY battery box that you have to assemble yourself. This unit comes with 16x 314 Ah Cornex cells and a JK 200 A BMS featuring a 2 A active balancing current.Unfortunately, the battery didn’t include a proper assembly manual, which made it impossible to put everything together the right way. There are two manuals on the website: one for the JK BMS and one for the PACE BMS. But neither matches the components I received. The JK manual, for example, shows wires as busbars, while the kit came with flexible orange busbars. It also shows a large breaker, but mine came with a smaller one. On top of that, the manuals only list what’s inside the box — not how to assemble it step by step.Even though I received this kit for free, I give my honest opinion as if I bought it myself. And at this point, I can’t recommend this battery because of the lack of proper documentation and the confusing mismatch between the manuals and the actual parts.Review policy: cleversolarpower.com/batteryreview

I’ll walk you through the installation, explain the key features like Bluetooth connectivity, automatic synchronization, and programmable relay functions, and show you how to get the most accurate state-of-charge readings for both lithium and lead-acid batteries.I also compare the BMV-712 to the Victron SmartShunt, the Lynx Shunt, and other options so you know exactly which one is the best fit for your system. Should you pay extra for the display, or stick with the cheaper SmartShunt that relies only on the app? I’ll give you my thoughts after testing both.Whether you’re building a van, RV, cabin, or full off-grid home, a reliable battery monitor is essential for protecting your batteries and knowing how much power you really have left. By the end of this video, you’ll know if the Victron BMV-712 is worth it, or if you should save some money and choose one of the alternatives.

Victron 100/30 MPPT Charge Controller Test + Review Cleversolarpower by Nick 2025-09-18 | Victron 100/30 MPPT: amzn.to/4pu59QG📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I review the Victron SmartSolar MPPT 100/30 charge controller and put it through a series of real-world tests. You’ll see how much higher your panel voltage needs to be compared to your battery before charging starts, how quickly the MPPT locks onto the maximum power point, and how it reacts when a cloud passes over. I’ll also explain what overpaneling really means, how much solar you can safely connect, and why you need to think about cold weather when calculating Voc.We’ll also cover the practical side of building your system, like what wire and fuse sizes to use, why you should keep the controller close to your battery or busbar, and how to avoid wasting money on cables. I’ll show you around the unit itself, point out useful features such as the passive cooling and Bluetooth, and walk you through the VictronConnect app so you can see what setup and monitoring looks like in practice.Victron charge controllers used to be considered expensive, but these days they are very competitive with other brands. In my opinion the 100/30 is one of the best controllers for the money. It’s reliable, solidly built, easy to use, and the app makes it simple to configure and monitor your system.I bought these controllers with my own money. This video is not sponsored.
Pecron E1500LFP Power Station Review Cleversolarpower by Nick 2025-09-11 | The Pecron 1500LFP: amzn.to/4pg9x5W2x 195W Solar Panels: amzn.to/4m38T8Z📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video, I review and test the Pecron E1500 LFP power station, an all-in-one unit with a 1536Wh lithium battery, a 2000W inverter, an MPPT solar charger, and a built-in UPS function. Instead of going over marketing specs, I put it through real-world testing to see how it actually performs.I look at the idle power consumption, surge capacity with appliances like a fridge, kettle, and microwave, and the UPS switchover speed during a power outage. I also measure how long it can realistically run household appliances such as fridges and TVs, and I test its charging performance on both AC and solar. Noise levels and sine wave quality are also put to the test, because these things matter in everyday use.Along the way, I explain where a power station like this really shines — for example as backup power for fridges, sump pumps, CPAP machines, Wi-Fi routers, or in areas with load shedding — and where it doesn’t, like in RVs or vans where vibrations could shorten its lifespan.
How Does an Automatic Transfer Switch Work? Cleversolarpower by Nick 2025-09-05 | In this short video i demonstrate how an automatic transfer switch works. This can be used for your rv when you connect to shore power. It automatically detects the shore power and switches over. When shore power is disconnected, it switches automatically back to inverter power. I have used 16A breakers on both the inputs and a GFCI + breaker combination on the output. I also made a ground neutral connection so the gfci can work properly. Check if your inverter has a ground neutral bond already.
Cheap Vs. Expensive Lugs For DIY Solar Power Cleversolarpower by Nick 2025-09-04 | Lugs on Amazon: amzn.to/3HRvGGXLugs on Aliexpress: cleversolarpower.com/go/alilugs$40 Hydraulic crimper: amzn.to/46lQVtK📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I show you why cheap cable lugs can cause serious problems in your solar power system, and how to spot the good ones. Most failures don’t happen at the panels or the inverter — they happen at the cable connections. And the quality of your lug makes all the difference.I’ll compare cheap lugs to proper ones side by side. We’ll look at the weight, the wall thickness, and why the cheap ones often slip straight off the cable even when you crimp them with the correct die. I’ll also show what happens when people try to “fix” the problem by crimping with a smaller die, and why that actually makes the connection worse.You’ll see the inside of a proper crimp, where the copper strands are compressed into a cold weld. This creates a gas-tight seal that keeps air and moisture out, preventing corrosion. In contrast, cheap lugs leave gaps that allow oxidation to build up over time. I’ll also demonstrate how the tin coating is much thinner on cheap lugs, making them corrode faster.Finally, I’ll share how you can quickly spot quality lugs before you buy them, what they should cost, and how to crimp them properly with a hydraulic crimper. A good connection doesn’t cost much more, but it makes your whole solar system safer and more reliable.If you want to build a system that lasts, make sure you’re not cutting corners on the small parts that matter the most.
Can a Flexible Solar Panel Beat a Rigid One? Cleversolarpower by Nick 2025-08-28 | 100W Rigid Solar Panel: amzn.to/4oUNJwx130W Flexible Solar Panel: amzn.to/3JyiOpE (price increased)📖 My Best-Selling book: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comIn this video I put a flexible 100-watt solar panel head-to-head against a rigid 100-watt panel to see which one really performs better on an RV roof. Most people choose flexible panels because they’re easy to install — you just glue them down without drilling holes or mounting brackets. But do they actually make as much power as a rigid panel, and how long do they last?To keep things fair, I ran multiple tests. First, I compared both panels flat on a simulated RV roof. After one hour, the rigid panel produced 61 Wh, while the flexible panel only managed 48.4 Wh — almost 21% less. Then I tested them freestanding with airflow underneath, where the rigid panel reached 69.5 Wh and the flexible panel came in at 58.6 Wh, still about 16% lower. I also measured panel temperatures and explained why heat is such a big problem for flexible panels.The results make it clear: rigid panels stay cooler, they perform better, and they last much longer before degrading. Flexible panels, on the other hand, tend to run hot and usually only last a few years before the plastic surface turns milky and blocks light. That said, they can still be useful. If you want a quick, lightweight installation without mounting brackets, or if you want a portable panel you can set in the sun while your RV stays cool in the shade, flexible panels can be a good option.

Installing a DC to DC Charger: Victron Orion Tr 12-24/15 Cleversolarpower by Nick 2025-08-21 | Link to the charger: amzn.to/3VeSCTiLink to the 12V version: amzn.to/3Jq9GmP📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comcleversolarpower.com/go-orion-manualIn this video I’m installing a Victron Orion-Tr Smart 12/24-15A DC to DC charger in my friend’s van. The van has a 12 volt starter battery and a 24 volt DIY lithium house battery that I installed a few years ago, so we’re using the non-isolated 12/24 version. I’ll explain why a DC to DC charger is needed when charging lithium from an alternator, how it protects your alternator from overload, and why I chose the non-isolated model for this setup.You’ll see a walkaround of the unit, how the input and output terminals are connected, and how the small remote port can be wired to a simple on/off switch. I also talk about cable length, fuse sizing, and why I prefer calculating fuse and wire sizes myself rather than relying only on Victron’s generic tables. We go through the numbers together and I explain how is size my wires and fuses.After wiring everything up, I connect through the VictronConnect app to set the charger to LiFePO₄ mode and adjust the input voltage lockout so the starter battery is never drained when the engine is off. I’ll show you how the engine shutdown detection works, how the charger responds when the alternator stops, and what the app can and can’t do in terms of monitoring.Finally I demonstrate the charger in action on the bench and then give you an overview of the completed installation in the van, with the charger, fuses, and cabling laid out.

Why a 100W Solar Panel Never Produces 100W Cleversolarpower by Nick 2025-08-18 | In this short video i show you the effects of cell temperature on the output of a solar panel. If a solar panel is hot, it will reduce the output voltage. Of course, the current is depending on the irradiance. Thats why in on a cold winters day you may have more than 100W from a 100W solar panel.

MPPT vs PWM Efficiency Tested Cleversolarpower by Nick 2025-08-14 | 📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comPWM: amzn.to/3Ht7ryEMPPT: amzn.to/3V3CHHuEver wonder why sometimes a PWM charge controller seems almost as efficient as an MPPT?In this video, I put them to the test and found something surprising — the difference was much smaller than expected.The reason? Solar panel temperature.When panels get hot, their voltage drops, bringing them closer to the battery’s voltage. This makes a PWM appear more efficient because there’s less “extra voltage” for an MPPT to convert into amps.Here’s what I tested:- Cool panel (35°C) → PWM efficiency: 74%- Hot panel (55°C) → PWM efficiency: 85%An MPPT still wins in all cases, but the gap shrinks in hot conditions.Whether you’re building an off-grid solar system or just curious about solar charging performance, this test will help you understand when a PWM can hold its own — and when an MPPT will pull ahead by a big margin.

DC Breaker vs Fuse: What Should You Use in Your Battery Bank? Cleversolarpower by Nick 2025-08-07 | Link to the breaker: amzn.to/4fmQ9PW📖 My Best-Selling book on Amazon: cleversolarpower.com/off-grid-solar-power-simplified🎁 Free Diagrams: cleversolarpower.comAre you still using a fuse and DC disconnect as your main battery shutoff in your solar power system? In this video, I show you a better alternative: a heavy-duty DC circuit breaker that can replace both components, saving you time, money, and reducing failure points. I’ll walk you through exactly how it compares to a Class-T fuse, NH00 fuse, and traditional DC disconnect setups.This breaker is rated at 500VDC and has a short circuit interrupt rating of 20,000 amps, making it ideal for off-grid solar systems running 12V, 24V, or 48V battery banks—even up to 2,000Ah. I explain why short circuit current matters, especially when using LiFePO4 batteries, and why cheap Amazon breakers with no safety certifications can be dangerous. I also cover the specs you need to look out for and run a real-world test to see when the breaker actually trips under a 200A load.By the end of this video, you'll know if this DC breaker is a good fit for your solar battery bank, how it stacks up against traditional fuse setups, and how to avoid common wiring mistakes that could lead to system failure. If you’re building or upgrading an off-grid solar setup, this is one upgrade worth considering.
