Review on 🔌 AIMS Power PWRIX120012SUL Pure Sine Inverter with Transfer Switch, 1200W Continuous Power and 2400W Surge Peak Power, Intelligent Cooling Fan, Transfer Time Less Than 20msec by Kholar Irvine

This inverter has all the features I was looking for but runs for a few minutes then goes into failure mode and stops working. It's too late to return it, so $286 wasted. I've ruled out under/over battery issues and it's not overloaded. In fact, sometimes it runs for up to ten minutes, and then for no apparent reason, a high-pitched warning beep sounds and the error light comes on.
