SUNGOLDPOWER 10000W DC 48V Pure Sine Wave Solar Inverter, Built-in 2 MPPT Solar Controllers, Max. 200A Battery Charging, AC Output 120V/240V Split Phase Inverter Charger (10000W DC 48V)

I bought the SPH10048P inverter last October. I spent about two months reading up on it and testing it out while waiting for miscellaneous parts to finish my garage setup. The system truly went live in January once my two ECO-WORTHY Powermega 48V 314Ah batteries arrived. Honestly, the wiring on the inverter itself is pretty straightforward. Most of my time was actually spent installing a Reliance Controls Pro/Tran 2 510C 50-Amp ATS and swapping out switches to 20-amp versions to safely match my grid box. My goal was simple: design a backup system that could handle our entire household load, minus the air conditioner. That design was put to the test sooner than expected. Back in February and March, our utility company, SCE scheduled multiple 8+ hour maintenance outages starting at 10 PM. Walking outside, our house was the only one lit up on the block. But the best part—and what made this worth every penny—was that our floor heating stayed on. My wife had just gone through cancer treatments, so keeping her warm and comfortable through those freezing nights was my absolute priority. The inverter transfer is incredibly fast. Nothing blinked, and everything stayed running seamlessly: two large LED TVs, two refrigerators, a freezer, a wine cooler, and we could use the microwave to heat up meals without any issues. I work in IT, so I’m naturally paranoid about dirty power, but none of my sensitive equipment noticed even a minor surge. I charge my Pluged-in Hybrid using slow charge with no hiccups. When the weather stayed bitter cold and I needed extra juice, I ran my propane generator to charge the batteries using an upgraded ECO-WORTHY Version 2 charger while keeping the Sungold inverter up and running. The iPhone app gives me all the real-time data I need to monitor the system from the couch. Although there's a fan that cools the inverter, it didn't matter since the installation is in the garage. This setup genuinely saved us during those freezing SCE outages. It is a solid, reliable piece of machinery, and I'm incredibly grateful to have it.

Excellent inverter with a TON of power; I use this as the heart of my mobile coffee trailer and it pushes two grinders, an espresso machine, and two fridges without breaking a sweat. On top of that, the customer service is fantastic. I had a part break in warranty and they helped me remotely diagnose it, then asked me if I'd be comfortable replacing the part myself (I was), and shipped it out to me. I've purchased two so far and will use them on all my coffee trailer builds going forward.

This 48vdc -10,000 watt 240vac inverter has been making clean steady power without any problems at all. Even runs my 5 hp 80 gallon tank air compressor just fine. Along with air conditioning, freezers and fridges. It’s very quiet but slight sounds can be heard from the fans when it heats up for a few minutes. Then back quiet again. When grid power goes out I’ll have no problem because this will keep everything running without gasoline generators. Also it switches to inverter power anytime the grid goes down without me doing anything. Solar panels will keep battery charged in daylight ( as soon as I get them installed ) so night and day I’ll still have everything running. If power is off for days it really doesn’t matter. Plus I’m saving a lot of money on my electric bill now. Inverter/ with batteries in the day and grid and charge batteries at night. ( My electric plan has free electricity at night ). This is the only inverter I’ve found that will allow you to set when it charges your batteries from the grid, and when you want it to go from grid power to inverter/battery power. Several times a day if you want. Then when you want it back to grid power. Or just stay on inverter power all the time. I charge batteries at night when grid power is free on my plan. Then go to inverter/batteries in the day. It has a huge amount of options ( 68 ) to do exactly what you want it to do. You also can add up to 10,000 watts of solar power into it ( has two MPPT’s ; up to 500 vdc ) along with the grid, and batteries, or any combination You can set how much current to charge the batteries from the grid up to 200 amps. Take your time and think what is best for your system and if it’s not how you want, then change the settings until it is. Not hard at all. I absolutely will be adding more of these 10,000 watt inverters, up to 6 total I think it says, as soon as I get more batteries. When this inverter switches, automatically, you set how you want it, to the grid or from grid to inverter/battery power, you will never notice it happens. No flicker or flash and doesn’t cause things to be reset like some do. Tv never flickers or blinks. It is clean, pure electricity. Maybe better than the grid? The price is unbeatable. Compare this to other big brands and this unit beats them all. The company has been around a long time with great products. Well worth the money…. Buy these. I’m not selling these. Just excited to finally get an inverter that really does work well how I want, not how they say I need.

I purchased the SungoldPower SPH10048P 10KW solar inverter in October 2025 to have the ability to charge an electric vehicle in an off grid situation, where there was no utility power, relying on solar power only. The small system that I assembled works as expected. The SungoldPower 10KW solar inverter easily Level2 charges at 25 amps, to my storage battery capacity. With the instructions provided, the SungoldPower 10KW inverter was easy to set up. I did have some questions, not covered in the manual. Customer support was responsive and quickly answered my query.

This is a great inverter at a great price. We live in Puerto Rico and as you can imagine, solar is a necessity down here. A couple of these in parallel, paired with 8 Sungoldpower 5.12kwh batteries and 10Kw of panels is enough to run my house even in the cloudiest of days. They also do very well running the stove, microwave and AC units. The only lacking area in my humble opinion is the monitoring app. The bundled wifi dongle and the SolarMan Smart app leaves much to be desired for us control freaks as it can't change settings remotely and, the monitoring and stats are lackluster at best. I would suggest to pair it with Solar-Assistant.io monitoring software and a RaspberryPi as it has excellent logging and control system features.
