Review on 1200W Pure Sine Wave Inverter With AC Charger, DC 12V To AC 120V Output - Off Grid Inverter For Lithium, Sealed, AGM, Gel, And Flooded Batteries By Ampinvt by Isaiah Bower

It’s running as an unattended battery backup for my French drain pump/float controller. 1/3hp pump, 100kwh LiFePo4 battery and I’m at 50% load with my initial testing.I opened the unit when I first got it to check the onboard outlet and the hot and neutral were reversed. They’re just spade connectors so it’s an easy fix.Installed the unit, tested the onboard outlet and no faults were found. I wired up a duplex out of the terminal ac output block and ground fault! I had to swap those as well. Someone will get hurt eventually if this isn’t fixed.At this price point, I can deal with the bad menus and the cheap feeling construction but products with a 120v ac ground faults should be taken more seriously. If you feel confident you can swap some wires around inside, it’s not bad for the price. Just weigh if the sketchiness of the unit is worth the saved money.
