500w Solar Grid Tie Power Inverter Pure Sine Wave DC11-28v to AC90-130v V1 Black

I have had the unit a little over 3 months and it has been operating continuously for that time. No problems. It is January 5th, in SE US, I am averaging 600 watts per day delivered to the home a/c (measured with plug in watt meter). Panels are in a south facing window. In this arrangement, in January, I see a maximum output of about 90 watts. Though my windows are a little dirty right now. I don't expect to break even on the inverter for a couple of years, BUT, the panels are for emergency backup, and the inverter allows for saving a little money while the panels would normally be in storage. When power fails, I switch to a solar charge controller and a battery system.

The product arrived on time and in good condition It was properly packaged and contained the inverter plus the power cable and instruction manual I have this inverter connected to four 100watts panels and this is connected together with two other inverters into a power strip that is plugged into the home grid. I like the fact that this unit has LED indicators for voltage and power load which makes it easy to see how well the unit is performing. Average efficiency after conversion runs around 60% The unit has been in operation around two months and so far I have not had any problems The unit is generally quiet and runs warm. I use a 12 V fan to cool the inverters which hopefully will extend the life of them.

I have had few different models of grid tie inverters one I have had for over 2 years and still works flawlessly this particular make and model stopped working after a few months. I went to unplug it and heard a pop inside. Initially I thought it was a just a fuse but after opening it up and replacing the burnt out fuse i wired it back up just for it short out again. The short is between positive and negative on the battery side inside the device. Ford those wondering if it’s a wiring issue on my end I plugged in another make and model to the existing wiring and it works fine so definitely an issues with this grid tie.

Works really well, and I like the terminal on it

Installed it with 560W of solar. At full sun the most that I get out of the inverter is 220W??? I have checked the panels by switching them to my battery bank charger and they put out rated power. Disappointed that I can't get the same output with this unit.

Very easy to set up and use works as advertised

burned out the day after return period expired

I've have had it for 2 years. (2) 300 watt panels hooked. I have it pumped into my eclectic grid. bottom line am saving about 30 dollars a month. Not excited but its worth the money

I have only been using it it for a short while but it seems to work as expected. Quite happy with the product so far. Thanks.
