Ok

The inverters work as they should but the one major flaw at least with these 1000 watt ones are the cooling fans don't come on till very hot or damage to the inverter happens . I got 4 inverters on 21 San tan solar panels and each inverter uses 5 panels and one uses 6 where the panels are flat on the roof. I had to wire up the fans on one side of the inverters and wire the fans to a power supply and timer so the fans run when the inverters are producing from mid morning to late afternoon. So the fans in my part should come on as soon as there is power available from a source like a solar panels. For more expensive grid tie systems i see that need 240 volt service to feed have there fans run when any power is being fed. This would allow these inverters to one run much cooler and allow to reach the stated rated output without burning up inside the inverter from over heating.

I can only tell good about the seller Boboran and this inverter. Runs like a champ, does what it is supposed to do and does it reliable.Running it at constant 850 watts to make sure not to overheat, but thats just me and being precautios

Because this grid-tie inverter (GTI) is low DC Voltage (10.8 - 30) you have to make sure the solar panels' output is within these numbers. You may need to wire the panels in parallel to keep the voltage down. I thought this GTI was Dead on Arrival, but then I realized the two 100w panels I have were in series, meaning the voltages add up. You need to look at the Voc numbers. Mine are 24.5v, so two of them is 49v, which is higher than the input for this GTI. *Luckily, I was easily able to switch the panels to parallel, and their output stayed at 24.5v, barely within the rated input tolerance.* Maybe the other reviews that say the GIT was DOA did not realize this?

it worked just like it supposed to...

yes

I'm a serious, well-studied Solar-tinkering self-installer guy. I have a 2800 watt grid tied-with-backup system with all top-line equipment, Canadian solar panels, Outback inverter and Schneider charge controllers. I have been adding some panels to boost my grid tie net-metering output using cheaper "China" inverters. I lucked out and found some inverters here on Amazon a couple years ago, "Soyo Source" brand, and they proved to be exceptional in design, performance, parts quality and build quality. Unfortunately they have disappeared from the American market. So....I decided to try one of these Vevor inverters. I'm giving 4 stars because the unit seems to be built pretty well, it DOES work, and I get the feeling if I don't "push" the input power to hard, it should last a long time. The company "Vevor" seems to be more reputable than the average "pop-up" companies that show up on Amazon and eBay with goofy named "cookie cutter" re-branded inverters acquired from the same OEM factories all the other "pop-up" companies are getting theirs from. They apparently market some other types of machinery and household devices and are a stable long term company that stands behind their products with communication and customer service, according to other positive customer reviews. Overall I'm satisfied with the unit, considering the $109 price point... it's OK quality. Compared to the other "Soyo Source" inverters I bought for $119 though, it's not anywhere close in terms of output performance, design ingenuity or build quality. My main concerns are: PROBLEM 1. The "Power Factor" performance of the unit in terms of the cleanliness of the output waveform and it's ability to push effectively into the grid, is AWFUL. The companies listing states it to be 98%. Not even close. I've used my test equipment and the inverter shows as low as 75% power factor. Today in direct noon, clear cloudless sky sunlight at cool 50 degrees (Fahrenheit) temperature on the panels after the inverter had

Wonderful Inverter it Ran way better than ExpectedHigh output i used 4 / 200w panels and got 600 watts out IN THE SPRING.Ive got two other systems they mppt wonderful

I'm pulling about 30 Amps from my 24V solar panels (~720Watts) and the Grid Tie Inverter gets quite warm which is what I would expect. I just need more of a 'personal burn in time' to convince myself that what I am observing is "normal". I would suggest mounting the Grid tie away from any structure ( I used a vertical antenna mount... the hole spacing was just about perfect and flexible enough I made it work). Also, mount the grid tie unit in a way that as heat rises, it is in the same direction the fans are trying to move the air out of the unit.

Watch the voltage 22-50 vdc. Theirs another one that does 12 vdc. Series jumps the voltage up to run the inverter. They both lower the electric bill. I run them at 43volts with 75-80 percent each panel.
