Has been working good with no issues. I like that the cooling fan speeds are regulated by the heat and load. Not just on or off. It's quiet also. Usually the loads have ranged between 2000 and 2500 watts. Dishwasher, washer, and microwave. Wattage use is shown on the unit screen. The only issue I noticed is the shown battery voltage registers .5 - .7 volts higher than actual. This might drain the batteries more than it should before cutting out but I have not allowed the batteries to drain that low.
I bought this one to replace another I spent $100 more on that the cooling died after 7 months and I'm struggling to get warranty service on it. I'll leave this one installed as it's working so good.
