Concept is great but this unit would over heat and shut down. Tried heat sinks to cool down , hopefully they will fix this issue. I was running the 800 watt 400per side , maybe using lower wattage panels might have solved

I had this inverter hooked up to two (2) Rich Solar 400 Watt panels. So a total of 800 watts. One panel on one side, one on the other. I was never able to get more than about 390 *total* watts out of it. Despite the panels being in full sun for about 3 hours on a clear day with blue skies and the panels properly oriented for direct sunlight.I thought that I must either be doing something wrong, or must have a faulty panel or inverter. For the fun of it, I bought a 2nd inverter of the same make/model (I was evaluating different micro inverters) and actually have 7 - 400watt panels total. I hooked two more panels up to the 2nd inverter and compared both the next day. Neither inverter ever achieved more than 390 watts of power total. I would have expected this number to be closer to 700-750.I even grabbed my nice digital clamp meter and measured the amps coming from each panel into the unit. Both were hitting about 6.5 - 7 amps. Panels are Rich Solar Mega 400 watt panels, with Max Power voltage at 41.2V and Max power current at 9.71amp. At 6.5 amps, these are putting out 268 watts. Assuming both panels are outputting that as they are both in the sun, that would be about 535 watts, yet the micro inverter is stuck at 390 watts total output.I read and re-read the manual thinking I had to be doing something wrong, but nope. They just can't output any more power. Both units acted identically. Their output from the phone app is what tipped me off to an output issue. Then I used my digital clamp meter to measure the output from each panel, then switched it to AC mode and measured the AC output downstream. I am sending these back.Also, it only includes one power cable. Good luck in trying to find another cable if you actually want to hook up multiple units. I found one or two on Ebay for about $40. no thanks, that's 1/4 the price of the inverter! I looked into making my own cable, but the ends are a weird M25 connector.Don't waste your time and money.

Just received it. I have two 200w Rich Solar panels connected. I am getting 260 watts at about 5pm in Southern California. Much better than other non micro inverters I have. It is 91 degrees outside and the inverter temperature shows 141 degrees. The inverter came with a 6ft M25 to 3 prong power cord cable. Also came with a wifi antenna, rack and panel mounting screws and nuts.

Don't waste your time or money. I went with this hoping it would have the Wi-Fi connection, but that was the first thing to suck; wouldn't connect no matter what i tried. Next was the bad power output. Though i have barely 800 Watts connected in solar, i can't get more than 250 Watts out from the inverter. After reading the other reviews I'm certain it's this inverter and not the panels. Just don't go with this device.

On the brightest of sunny days, I mean 25° tilt, south facing, direct sunlight, not a cloud in the sky and two new 360 watt panels…I got 278 watts out of it. One panel, 98 watts. No thanks.

The inverter leaks the neutral connection to the body of the unit. Thus if you properly ground your array it will connect your neutral to the ground at the array.This is very unsafe.

I purchased 2 units both lasted 3 months and then stopped working. I was going to attempt to return under warranty but found out the shipping back to China is 80% of the cost of the unit. It makes more sense to eat the loss of both units than spend almost double and a product that most likely will fail again. This could be because of region of installation. I'm in Florida and they could be getting extremely hot. They do shut themselves down thermal management however still failed. I would suggest spending more on a US based product and warranty.
