Be Careful of the Low DC Voltage Requirement
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?

worked great bertter than some others..
it worked just like it supposed to...

POSITIVE review from "Serious solar guy", some "performance" disappointments, will update later
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
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

Orientation might matter ...and other observations
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.

Works great
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.

Easy setup.
Ordered two for two 800 watt banks 1st one looks good, but the second one after the initial start up. we lost the red and green indicater.

Works well, and is very well built, the price is about the same as the very cheapest on the market, but it's actually solid. Takes more juice than I would like before it actually starts inverting. I got both the 12.8-30 volt, and the 20-45 volt version. Batteries like I want to go with the charge controllers and panels I already have costs way more than these. Should have sold the power back to buy the batteries. Live and learn.

This inverter with the wind turbines is the perfect combination to save energy. We have a lot of customers asking for more. Price, quality and performance is the perfect equation. Thanks
