![Best DIY 48v Solar Inverter Has A 2,000W Problem [PROOF] @theresatrickforthat](https://i.ytimg.com/vi/KkerIdchP0Q/maxresdefault.jpg)
Uploaded August 2026 | Updated September 2026, 2 hours ago
The Humsienk 48V 12000 Plus+ split-phase inverter is advertised as a 12,000W unit at $1,399… but I load-tested it to failure and the manual tells a different story. Split-phase rated output is 10,000W, not 12,000W; the 12,000W figure is the PV input and the 50A pass-through. Here's the surprise: at 10,000 real watts it's still the best dollar-per-watt off-grid inverter I've tested, it idles lower than any true 12kW unit on my bench, and it pairs perfectly with a single 200A-BMS battery.
NOTE: Since making this video, I am pleased to inform you that Humsienk has updated the marketing materials on the website to accurately reflect the correct inverter output specifications.

![DIY Mini Split Install: Save $9,000 [Step-by-Step Guide]](https://i.ytimg.com/vi/MRPfCzLSwMA/mqdefault.jpg "DIY Mini Split Install: Save $9,000 [Step-by-Step Guide]
DIY mini split install step by step: I was quoted $10,000 to have a mini split heat pump installed. YIKES! So I did it myself with a $409 unit from Amazon and saved over $9,000. This is the complete step-by-step DIY mini split installation guide: mounting the bracket, drilling the wall penetration, flaring the line set, wiring 120V, pulling a proper vacuum, and leak testing. Im a licensed HVAC technician, so youre getting the real procedure…not the shortcut version. Then I tested it in a 105°F extreme heat warning and got a 35-degree temperature split. Best part: this unit has a generator mode that caps output at 30%, 50%, or 80%, which makes it one of the most solar-ready mini splits you can buy. Ive got a full companion video showing exactly how I run this entire system off solar and pay nothing to operate it.

NOTE: At the at the time of making this video there is a coupon you can clip on the Amazon page and save an extra massive 10% on your order! That brings the cost of this mini-split down to a crazy low $368! WOW!!!
