I purchased this all in one to run my 2 freezers and refrigerator from my solar system. Works great. Had an issue 2 months in of using it and Sungold Power was quick to respond and get the issue solved. I would recommend this unit. It is an easy setup to use.

5.0 out of 5 starsOutstanding All-in-One Power Solution - Flawless Performance After 2+ Months!I purchased this SUNGOLDPOWER UL1741 5000W 48V Solar Inverter on July 29, 2025, and let me tell you—it's been an absolute game-changer for my off-grid solar setup. As someone who's dabbled in renewable energy for years, I was looking for a reliable, all-in-one unit that could handle my 48V battery bank, integrate seamlessly with my panels, and deliver clean power without the headaches of multiple components. This inverter checked every box and then some.Right out of the box, the build quality impressed me—solid, well-labeled terminals, and clear instructions that even a semi-DIYer like me could follow. Setup took about an hour: I wired it to my 48V lithium bank, connected my 120Vac grid input for hybrid mode, and hooked up my 4kW solar array to the 100A MPPT charger. No fuss, no sparks, just smooth sailing. The pure sine wave output has been rock-solid, powering everything from my fridge and lights to my 2000W workshop tools without a single glitch or voltage drop.Fast-forward to now (mid-October), and this beast has been running flawlessly 24/7. The 100A MPPT solar charger pulls every watt from my panels, even on cloudy days, and the 40A AC battery charger kicks in effortlessly during low-sun periods or outages. I've monitored the efficiency via the built-in display and app—consistently over 95% on solar-to-AC conversion. No overheating, no error codes, and the fan is whisper-quiet unless it's under heavy load (which it handles like a champ).If you're building or upgrading a solar system and want one unit that does it all—charge, invert, and protect—don't hesitate. This UL1741 is a powerhouse at a price that blows the competition away. Highly recommend for RVers, homesteaders, or anyone going green. Five stars all the way—worth every penny!

Bought one for my off grid house to replace the inverter that wouldn’t run the washing machine. It runs the washing machine actually better than the gas generator that I was having to use whenever I wanted to do laundry. I’ve had it for about two months and so far I’m very happy with his performance. The only thing I might like to see is a Bluetooth app that would allow me to track input output. The price was very reasonable and it’s exactly what I needed. The fan is a little noisy, but that’s not a big deal.

Easy to install alongside their 48v server rack batteries. System has been up and running 24/7 for about a month and no issues so far. I would like there documentation to improve regarding configuring the BMS communication via the RS485 port. Will be keeping a eye on reliability especially during the higher loads I except this summer.

We bought this equipment in June 2023, right out of the box, problems. The sellers Tech support has no idea how to solve issues. it is a constant guessing game and trial and error with the equipment. It worked for about a week, then problems again. Supposedly you can wire them in multiple patterns for max output. Again constantly with errors and faults. I worked with Jack at the sellers company for which is on CA time and there is no support outside of their business hours. I got so frustrated just asked for a refund and Amazon took care of me, the seller wanted me to pay for shipping their equipment back and they wanted to "make repairs" and send me this garbage back to fight some more, NO THANKS!
