SUNGOLDPOWER 10000W DC 48V UL1741 Solar Inverter,Support Parallel, Built-in 2 MPPT Solar Controllers, Max. 200A Battery Charging, AC Input/Output 120V/240V(settable) Inverter Charger(10000W DC 48V)

Excellent inverter, very powerful and reliable. The SUNGOLDPOWER 10000W DC 48V UL1741 delivers stable performance even under heavy loads, making it ideal for residential or small commercial solar systems. The build quality is solid, pure sine wave output works perfectly with sensitive electronics, and the UL1741 certification provides great peace of mind. Easy to set up, quiet, and highly efficient. Very satisfied with this purchase—highly recommended.

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.

This inverter is an amazing product, especially for the price. I use it with about 8500w of solar, used Tesla battery modules, 240v grid input. Since my electric provider doesn't pay as much for the power I give them as they charge for the power I buy, I use the inverter in Solar/battery/grid mode. This means everyday I'm charging my batteries with the excess Solar, and every night I discharge the batteries. I set my max amp rate to 150 amps, and the inverter has no problem handling it and maintains temps well. I will soon up that to 175 amps as more batteries are used. The switching between battery and grid after I've discharged my batteries is seamless, and the only way I notice is from the beep on the inverter. About half my house is on this inverter, and none of the electronics lose power during the switch. The 2 mppt's make it easy to wire panels from different sides of the roof. Great product, will be buying a second one soon to up my power to 20kw!!

First thing is, it comes packaged nicely. next is really easy to install. Comprehensive instructions. If you don’t understand any of the instructions, you can email support and they get back to you right away. The app was easy to set up so we can check on our power production and usage even when we’re gone. I thought I was having trouble with the inverter, not activating the solar input, however, it turned out to be a bad battery in my four pack. Once the battery is replaced, the solar was detected properly and fed into the system. We have it set up for solar first with battery back up , and when it switches back to the grid in the evening when the sun goes down, you can’t even tell. It has been running now for a few weeks without any problems. If you have any problems, Once again contact customer service. They are wonderful to work with and will even help you with the settings .

I am using this inverter inline as a battery backup with my utility grid; no PV, and not off-grid. This inverter seems to be using power from my batteries, and because of that it is constantly cycling from drawing battery power and charging, mostly constant charging, even when this feature is OFF. Its not drawing power and supplying out, it's just consuming and recharging, forever. Thats just extra consumption I'll see on my utility bill. Number 2 is the web app, or lack thereof. The manual just says "easily control through the app" but not what app. The app I found that works (solarman pro) doesn't allow any control, only monitoring and its not the greatest to access that information. Fourth would be the terminals for AC, could be better and larger (#6AWG barely fits). Two stars because it's fairly well built, easy to use and UL listed and WHEN doing what its supposed to (DC to AC inverter) it does well, fast, and quiet enough for the price. It seems to not care now if I disconnect the batteries, it just alarms low DC voltage, continues to try and charge, while acting as a pass though from grid to house. Even if that seems dangerous, im ok with it as it allows maintenance on my battery side without losing power to the circuits its backing up.

This is a very nice inverter. Works exactly as it's supposed to. I really appreciate that I'm able to have two different solar arrays come in and power the unit. Furthermore on a sunny day I can easily charge my 30 kilowatt battery Bank in less than 3 hours.

4 months little to no use and now it won’t turn on. Do not buy

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.
