I bought a 12000w LF AGM, problem from day one , cannot be connected the hardwire simultaneously with the house power, tripping the grid panel breaker , with the first installed I had a push button circuit breaker on the battery but kept on blowing it I removed it then blew up all the mosfet and other parts in smoke . I now replaced all the damaged parts , with extras protection I can use the receptacle but not the hardwire if I attempt to do I will get sudden low battery warning and tripping all circuits breakers.
please any suggestions?
Thanks
