Are these FET drive compatible with PJ 12000 AGM? GS control boards only have a single FET board output connector, not a double like PJ does. In addition, the PJ FET boards would need either modified with the addition of a zener diode to each one (to prevent FET failure due to the stronger drive) and/or outright replacement with a set of GS LegacyFET boards (best case). Due to the design limitations of a PJ mainboard, you would not be able to exceed much over 6kw output with a GS setup. But there's also no way the "12000W AGM" transformer will be able to do 6kw continuous in the first place. Quote Link to comment Share on other sites More sharing options...

You might have honed in on at least one of the issues 😉. None of the AC input or output leads (nor the DC input leads) on the inverter should be short-circuited to the chassis. The lowest connection between any terminal and the chassis should be >1 Megohm. Quote Link to comment Share on other sites More sharing options...
Lener Posted May 2 Author Share Posted May 2 I am not sure if this is an isolated incident, I have had a lot of issues tripping breakers blew up Fetts and so on with my 12000 watt AGM, after taking the unit apart many times tracing wiring , I discovered some of the wires were crossed (output) after fixing these issues the machine has been working for quite awhile without any problem crossing my fingers. Unfortunately there’s no manual for reference..!I been running the living room area TV and satellite devices and a small deep “freezer at night “with a power transfer of course I don’t want to peeve my queen when she is watching TV. 1 Quote Link to comment Share on other sites More sharing options...
