SUNGOLDPOWER 10000W 48V UL1741 Solar Hybrid Inverter, Built-in 2 MPPT Solar Controllers, Max 200A Battery Charging, AC Input/Output 120V/240V(settable),Pure Sine Wave(WiFi and BMS COMM/Grid Feedback)

The 10kW inverter works pretty well. Setup was a little complicated for my use case. I am using this in an off-grid configuration to power a few high-power devices in my home and garden, most of which have their own Transfer Switch for when the Sun goes down. I have 2 solar arrays in my backyard which work well with the 2 MPPT inputs. My 1-unit system has enough power to run a 3.5kW Air Conditioning compressor with a SoftStart module in the summer (I highly recommend a SoftStart module for inductive loads like HVAC), or 1-2 electric heaters on cold winter nights. The inverter is installed in a special corner of my basement. I installed a special box with breakers and ran wires and conduit to all the places I need. The internal fan makes a little noise, but the beeping can be turned off. The batteries I use are just some golfcart LiFePo batteries. Their PC software for USB works, but divides some voltages by 4, probably because they reuse their firmware code for 12V models. EDIT: took me a while, but I figured out the included wifi data logger module only works with its special app. I had a minor configuration problem, but Customer Support was very responsive and sent me the correct Voltage parameter logic to make sure I don't keep cycling and clicking the relays on cloudy days: 15<12<04<14<35<37<05<(09,11). Overall experience is positive. Very nice box with a lot of integrated functionality.

This inverter has been working flawlessly so far. The 10000W power output is more than enough to handle multiple appliances at the same time, and it runs very efficiently. Installation was straightforward, and the system feels solid and well-built. It’s a great option for off-grid or backup power systems, providing stable and reliable performance. Overall, excellent quality for the price and highly recommended.

Received and installed my inverter as an off grid solution to power my pool equipment. System uses PV, Battery and Mains thru a transfer switch. Install and Configuring was straight forward, and Inverter communicated with my battery (RuiXu 48/16Kw) just fine. System is working and switching between power sources as expected using setting 01 at SOL and Battery Charge at CSO. I did initially have an issue with battery not charging at full 60A capability and some settings stuck, but after a factory reset everything works as expected. Support for my issue was prompt ( chat immediately and followup email the next day) so no complaints there.

This inverter / charger is amazing. I power a large food truck with mine being fed by eight 51.2V / 100AH batteries, and I regularly run it at 7-10kW output. Eight months in, no issues. My only complaints are that the AC input and output terminals should be larger. It is extremely difficult to feed stiff 6 gauge wire into them. They are barely large enough to accommodate 6 gauge - which is the minimum size that should be used in the application. Also, be sure to check the internal grounding lug near the terminals. I discovered that this was only finger tight on mine. This would have caused issues if had I not noticed it. In my application, it runs the following: a 240V hot dog roller grill, a commercial microwave, two large rooftop air conditioning units, a bun warmer, a warming cabinet, a induction cooktop, two refrigerators and a stand-up freezer, and all indoor and outdoor lighting and electronics - simultaneously if I need to. It's a beast!

Work perfectly after 4 months
