Is this the most POWERFUL off grid inverter ever made? DavidPoz 2022-11-11 | Part 3, Schneider Inverter. We push it to it's limits by load testing it.This is a heavy, transformer based inverter made for off grid and on grid both. This makes it a hybrid inverter. The Schneider XW PRO 6848 is battery based for any nominal 48V battery including lithium Iron Phosphate (LiFePO4). In this video I put the inverter through rigorous load testing. Will it meet the spec in the manual? I throw power tools on it, water heaters, space heaters, etc. I try to load this XW PRO.Chapters:0:00 Intro2:00 Overload Duration test on 240V4:56 Power Tools on Inverter, 12" Miter Saw7:59 Welding off grid11:21 L1-N, Load Imbalance Testing21:36 ConclusionDownload the Operation Guide for the XW PRO inverter here: solar.se.com/us/en/product/xw-pro-120-240v/#downloads Scroll down and click on "User Documentation" then you can download the "XW PRO Owners Guide_990-91227"PDP stands for Power Distribution Panel. Schneider makes two models of the PDP for the XW PRO inverter. There is a small, and large PDP. Both come with one 250A circuit breaker as a battery disconnect, and some AC circuit breakers. Both have a means to connect the single 250A breaker to one inverter.The small PDP is made for one inverter only. It takes up less room, and costs a little less than the full size. As of this video, it is about $650 which makes it a real bargain if you know for certain you only need one inverter. This mounts under the inverter.The large PDP takes up a little more room than the small PDP. It mounts next to the inverter, and comes with a wire-way that mounts under the inverter. The large PDP can accommodate up to 3 inverters allowing you to expand your system over time. As of this video, it costs about $1,200. It's only worth it if you know you will want more than one inverter (now or in the future). ---------------------------------------------------------------------------Signature Solar Affiliate Links:Schneider XW PRO inverter: signaturesolar.com/schneider-conext-xw-pro-6-8kw-inverter-charger-48v-120-240v/?ref=4_rHcgZ9x-TiF-Schneider PDP, Large: signaturesolar.com/schneider-xw-power-distribution-panel-1-pole-250a-no-ac-breaker/?ref=4_rHcgZ9x-TiF-Schneider PDP, Small: signaturesolar.com/schneider-xw-power-distribution-panel-mini-pdp/?ref=4_rHcgZ9x-TiF-Schneider kit with inverters, PDP, and charge controllers: signaturesolar.com/bndl-dc-coupling-with-dual-inverter?ref=4_rHcgZ9x-TiF-Complete Off grid kit: signaturesolar.com/complete-hybrid-solar-kit-schneider-dual-xw-pro-13-6kw-120-240v-output-30-72kwh-eg4-ll-v2-battery-powerwall-12710-watts-of-solar/?ref=4_rHcgZ9x-TiF-Battery, 30.72 kWh, LiFePO4, EG4-LL, with cabinet and busbars: signaturesolar.com/eg4-ll-lithium-batteries-kit-48v-100ah-x-6-30-72kwh-6-server-rack-batteries-with-pre-assembled-enclosed-rack-with-door-wheelsac/?ref=4_rHcgZ9x-TiF-Schneider Bundle with Mini-PDP: signaturesolar.com/bndl-dc-coupling-with-single-inverter?ref=4_rHcgZ9x-TiF----------------------------------------------------------------------------Amazon Affiliate Links:Power Meters (Din Rail): amzn.to/3A8v8FjSPD, Surge Protection Device: amzn.to/3U9YBWW4/0 Lugs, UL: amzn.to/3SGwP3qWire Cutters: amzn.to/3sD0BLUWire Crimpers, Hydraulic: amzn.to/3gUUZtSService Entrance Connector: amzn.to/3FrNPXZZip Ties, UL: amzn.to/3DF1ARXCable Tie Tool: amzn.to/3sIRXvsTorque Screwdriver: amzn.to/3DS8nYRDriver Bits for Electrical Terminals: amzn.to/3DIWS5L“As an Amazon Associate I earn from qualifying purchases.”---------------------------------------------------------------------------Disclaimer:Products in video may have been provided to David Poz, LLC at no cost for the purpose of the review.

Why do I think this is the best battery? DavidPoz 2022-09-01 | Let's compare the features of these popular server rack batteries and determine which is best for off grid solar? One is the Jakiper Pro from Orient Power, and the other is LifePower4 from Signature Solar. LifePower4 battery from Signature Solar is my favorite for building up a large scale system. This is for people wanting to back-up their whole house, or go off grid completely. Combine 2 or more batteries inside the enclosed cabinet for a perfect setup. The 48V batteries from Signature Solar come in 2 versions, with or without a screen. I don't think the screen version is worth the extra cost if you plan to use a central shunt anyways. ---------------------------------------------------Signature Solar Affiliate Links:LifePower4 battery without a screen: signaturesolar.com/eg4-lifepower4-lithium-battery-48v-100ah/?ref=4_rHcgZ9x-TiF-EG4 battery with a screen: signaturesolar.com/eg4-ll-lithium-battery-48v-100ahd/?ref=4_rHcgZ9x-TiF-Server Rack cabinet with locking door, and copper busbars: signaturesolar.com/pre-assembled-eg4-enclosed-battery-rack-6-slot-wheels-included/?ref=4_rHcgZ9x-TiF-NEW!

Wall hung Lithium Battery looks amazing! Powerwall style from Orient Power. DavidPoz 2022-08-20 | This battery is built like a tank! Orient Power sent me their new Powerwall style battery! It's a 51.2V (48V) LiFePO4 battery that will hang on the wall right next to your inverters. This will keep your floor free of large racks. The cell chemistry is LiFePO4 (Lithium Iron Phosphate) which is the leading chemistry for home storage. Each battery works with 48V equipment but is technically 51.2V nominal, 100Ah. This means you have 5.12kWh of capacity. I run through a series of tests and was happy with it's outcome. Yes, I was able to overload and shut down the battery, but that was pushing it past it's 100A rating. When staying below 100A, the battery worked as advertised. This is an excellent choice for small off grid solar systems where you don't need a full rack of batteries taking up floor space. Mounting a few of these on the wall will likely make for a cleaner installation on small off grid builds5% Discount code: DAVIDPOZ Powerwall battery is the newest version and hangs on the wall if you don't have a lot of floor space.

Victron vs. Growatt solar MPPT charge controller efficiency test DavidPoz 2022-07-15 | We all know Victron makes very efficient equipment, but how much more efficient is it compared with the Growatt? Let's find out.Victron vs. Growatt solar MPPT charge controller efficiency testI'm testing the Growatt SPF 5000ES inverter which has a built-in charge controller. The Victron is model 250/100. The Growatt inverter is an all-in-one unit with both a charge controller and inverter. These all-in-one units really do well when you use the power as it's being created.I'm taking all measurements using my multi-meter so the results will be consistent between the two products.Note: The Victron MPPT charge controller has a maximum input of 250V and the Growatt MPPT charge controller has a maximum input of 450V. This means you can (usually) save money with the higher voltage by not needing a combiner box and circuit breakers.

Safety Concerns with Auto Transformer and Growatt 240V inverter SPF 5000 ES DavidPoz 2022-01-28 | I've received several questions regarding safety concerns about my inverter setup. This video is to answer those questions. I have two inverters running in parallel. They are Growatt SPF 5000 ES purchased from Signature Solar. Each inverter is 5kW, so combined that's 10kW of power. I've combined it with 30kWh of battery capacity. The batteries I'm using are Gyll (EG4) 48V LiFePO4. This is all part of my off grid solar system running my whole house and garage.The inverter makes 240VAC single phase. I'm using the auto-transformer from solar-edge to create a neutral. This "splits" the 240V in half, providing me two 120V legs. Keep in mind, this is a DIY channel. I'm using my equipment off grid. Please be safe for your own setups. Filming and editing this video took place over the course of 2 weeks.

Building a Solar Generator, Powerwall, System for off grid Tiny House on Wheels DavidPoz 2021-09-03 | This is a complete build of a solar system that will power my friends Tiny House on Wheels. The video shows all the layout, connections, and testing. So make sure to watch to the end if you want to see it fired up and working.My friend's nick-name is Poet. Poet built his Tiny House on a trailer to it can be towed, THOW. He built it and bought a piece of land completely off grid. There is no grid power available. There is a well on the property that requires 240V AC to power it. Right now, Poet, uses a Honda Generator model EU7000 which can output 120V and 240V split-phase like we use. The well pump is submersible, inside the well. The cord comes out of the well and has a 30 amp twist-lock plug on the end. This is what he plugs into the generator to run his well. This means that in order to have water inside his tiny house, Poet must fire up his generator. This is costly, noisy, and inconvenient. I'm building Poet a solar power system to handle his needs for the well pump, and a future air conditioner. Below are some of the parts I'm using:Inverter: I'm using the Growatt SPF 5000 ES model. This inverter has a built-in solar MPPT charge controller (up to 6,000 watts of solar). It can output up to 5000 watts of AC power at 240V 60 hertz. This inverter can also charge the batteries from an AC source, such as his generator. I bought the inverter from Signature Solar. Auto-Transformer: This device can "split" the 240VAC output into two legs of 120V each. In North America many household appliances run on 120V. This was also bought from Signature Solar. Update: There is no longer a discount code available.Circuit Breakers and box: These were purchased from Industrial Control Direct.

Parallel 3 Inverters Together, off grid 48V 120/240, 1-Month Update DavidPoz 2021-08-20 | Last month I paralleled 3 inverters together to increase their output. Now it has been one month of running my home and garage on them and it's time for an update. Bottom line, they have been working excellent. The inverter is from Growatt. It's the SPF 5000ES model. It can output a continuous 5000 watts (5kW) of AC power at 230 or 240 volts (50 or 60 hertz). I'm using an auto-transformer from Solar Edge to provide a neutral so that I can have 120/240V split-phase. Total output: 15kW Each inverter has a built-in solar MPPT charge controller.

DIY Mini-Split Heat Pump, Full Installation, 2021 DavidPoz 2021-08-07 | Wow, this is the most efficient mini-split I've ever seen! I'll show you the full installation. Every step is covered in detail. This is my first time installing this type of mini-split heat pump and it worked great. I'm installing this in my garage, workshop, to cool it in the summer, and help heat it in winter. The installation went pretty smooth. The included manual shows you how to install most of the parts. I installed this in the middle of summer, and it's hot! After 48 hours of run-time the mini-split had the whole garage cooled to 64°F and is only drawing a tiny 130 Watts to maintain that temperature! Wow! That's amazing how the inverter driven compressor can draw so little power.The manual says to just pull a vacuum using a vacuum pump. However, I also include using a nitrogen tank to pressure test the system and check for leaks. Since this mini-split can run on straight 240V (no neutral) I can run this on my Growatt inverters that I installed in a previous video. Actually, I could install up to 5 of these mini-split air conditioners on just one Growatt 5000 inverter. That's a cool way to move some loads off the grid.

Water Heater Diversion Load and Capacity Test DavidPoz 2021-05-15 | Let's find out what the total usable capacity is of my mixed up battery bank. I have some LiFePO4 and some Li-NMC cells working together in the same battery bank. This is not the ideal way of building a battery bank. I did it this was because I've been adding batteries over time as I get the money and build them up.Half this video is setting up the wiring for the bottom water heater element on my hot water tank. This will server two functions. First, it gives me a fixed load for capacity tests (which I'm doing in this video). Second, it will allow me to wire the bottom element to a relay and control it as a diversion load. I'm not doing the diversion relay in this video, that will be in a future video.

Building a Solar Pool Heater for Huge in-ground Swimming Pool DavidPoz 2021-04-14 | Wim lives in Massachuesttes and love to swim. Unfortunatly, the swimming season is short, and his pool is shaded most of the day. We decided to build a Solar Pool Heater. We found some 4x8 solar collectors (hot water panels) on craigslist. They are new-old stock, and sold cheap. So cheap in fact, that it was cheaper to buy these panels then to make our own collectors from scratch.

DIY: Super Insulated She-Shed with Radiant Floor heating DavidPoz 2021-04-02 | My wife is now working from home, as I'm sure many of you have needed to do. Since our home is rather small she was working on the kitchen table. With two kids also home, this was not great for all of those ZOOM meetings. So I made her a home office from our tool shed. The outdoor tool shed is fully insulated with Dense-pack cellulose insulation. Some would say it's super insulated. The walls and floor are about an R-42. The ceiling is more because it's packed all the way to the roof. This is known as a hot roof since there is no venting. I removed the tools, and siding from one wall. I installed two new windows. These windows are double hung, double pane, insulated glass. Not the lowest U-factor, but it's OK. Having two windows allow for a cross breeze when both are open. Since there was no heating system, I needed to add one. We decided on an electric radiant floor. This was a DIY kit with the electric resistance wire already attached to a mat. This mesh mat made installation fast and easy. The kit is called from LuxHeat. Link below.After that I used a self-leveling compound (similar to thin-set, or cement). This was poured 1/2" thick to embed the wires. I had some real trouble with this step as you see in the video.The walls are covered in bead board paneling and painted white. There are 6 recessed LED light fixtures. The floor is a oak laminate, floating floor. Thanks to my wife and daughter for helping in the build.

Best Value Inverter, All-in-one MPPT Solar Charger, Growatt SPF5000ES, Part 1 DavidPoz 2021-03-27 | Part 1, Testing and Review of Growatt SPF5000ESThis is just my first part of my testing and review of the Growatt SPF5000ES inverter/charger. This is an all in one unit with a 5kw inverter, 80 amp AC charger, 100 amp solar MPPT charge controller. It's a great value at only $900 at the time of this video.This is a 48v inverter/charger made for off grid use. You can use the grid for charging your batteries as a backup, but not for back-feeding the grid. It's single phase, 240v AC only. So you will need a transformer if you want to get 120/240v split phase out of this. I'll go into more details on the split phase in an upcoming video. This is the best value, cheapest, inverter I've tested so far. Yes, it's cheap at $900 for all the components you get. In future videos I'll continue testing to see how well it holds up.

Cheapest 48 volt LiFePO4 Battery, Pre-Built with BMS, Testing and Review, Gyll from Signature Solar DavidPoz 2021-03-07 | This is the cheapest pre-built battery for 48 volt off grid powerwalls. At only $300/kwh nothing else comes close. This is a LiFePO4 battery, pre-built from the factory with a BMS, circuit breaker, all in a beautiful case. It's ready to go to work with your powerwall and off grid solar system. No need to add a BMS. It's rated for nominal 51.2v so it works with normal 48v equipment (inverters and MPPT charge controllers). This is the Gyll brand sold by Signature Solar. It's 100ah, 5,120wh. That's over 5.1kwh per battery!Retail price as of this video is $1,500, which is less than $300/kwh. Update: There is no longer a discount code available.In the video I do a full capacity test. I test the BMS for over-current protection, and over-voltage protection. Finally I connect the battery to my computer to see what can be read. Overall, I'm very impressed with the build quality of this battery. I think it's the cheapest at $300/kwh. I haven't seen any other 48v LiFePO4 batteries (pre-built with BMS) come close to this price point.Amazon Affiliate Links:Resistor used to pre-charge inverter: amzn.to/30lgg4c “As an Amazon Associate I earn from qualifying purchases.”Affiliate Links:Growatt 5000W Inverter with 450V MPPT Charge Controller 5000ES: signaturesolar.com/growatt-48v-5kw-450vdc-stackable-off-grid-inverter/?ref=4_rHcgZ9x-TiF-Auto-Transformer, 5000ES: signaturesolar.com/growatt-5kw-split-phase-transformer/?ref=4_rHcgZ9x-TiF-EG4 Battery, 48V, 100Ah, 5.12kWh, LiFePO4, Server Rack design: signaturesolar.com/shop-all/batteries/?ref=4_rHcgZ9x-TiF-Waterproof EG4 battery: 48V LiFePO4 Lithium Battery with Bluetooth, EG4 Brand: signaturesolar.com/eg4-wp-lithium-battery-48v-100ah?ref=4_rHcgZ9x-TiF-Disclaimer:My videos are in no way intended to be instructional "how-to" lessons.

Why is this new battery The Gamechanger from Battle Born DavidPoz 2021-03-02 | Comparison video between Battle Borns flagship battery (12v 100ah) to their brand new battery (12v 270ah). Why is this new one so special? Both are sealed batteries, water resistant. Both have LiFePO4 cells (lithium iron phosphate). Both are 12v. The new one just looks more expensive per kwh. Update: I made a mistake in the spreadsheet. When I did my conversion from cubic inches to cubic feet I divided by the area factor, not volume factor. The cubic feet volume of the original battle born should read 0.46, and the new model 1.23. Both have the same volume to kwh ratio of 0.38 cu.ft./kwh. Sorry for the mistake, Thank you to David James for pointing it out to me in the comments.

Cheapest Multi-meter comparison, Which is the Best Value? DavidPoz 2021-02-26 | Which multi-meter can measure DC amps best? I'm testing all my DMM, Digital Multi-meters. I'm testing them against my Victron Smart Shunt 500 for accuracy. Since the Victron Smartshunt is Bluetooth, we will see what it's recording on the phone app. I want to find out which one is most accurate. I also test my DIY capacity tester meter (built in a previous video). Finally I calibrate my capacity tester using a rotary tool.Video making capacity tester: youtu.be/sJ-sy8Osqr0Amazon Affiliate Links:Uni-T Multi-Meter 210E: amzn.to/3ks9jYeThe next multi-meter to buy, UT216C: amzn.to/3kAgNZyCapacity Tester: amzn.to/2O9melNVictron SmartShunt 500a: amzn.to/3ksgpMw“As an Amazon Associate I earn from qualifying purchases.”If you would like to help support the channel please go here: patreon.com/DavidPoz
