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.

The unit was working fine until I saw this past week that the light was constant red, looked at it and the A/C cord connection had burned out. It has just been 4 months, and I have contacted seller through Amazon help and have not heard back from them. Do Not Buy if you want something that lasts longer than 4 months. I hope the seller does the right thing and replaces item. I'll repost a review if the correct thing is done.

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.

burned out the day after return period expired

Very easy to set up and use works as advertised

Works well and am satisfied.
