I was hoping one you folks could send me a fault code list so i can trouble shoot a recent issue on one of my 8000w 12v 120/240 split inverter. It ran fine for 4+ yrs until 2 weeks ago. Upon startup it beeps four times and has than one continuous beep. I tested all Mosfets they checked good. Right now i am running off of my backup 8000watt. Any help would be greatly appreciated.
Thanks,
Jason

I was testing a spare ebay control board and it beep 4 times and then continue beeping and check no outout 120v or 240 v . Seller send a new 10.3 contorl board with LF driver and the PS inverter works again . I have no fault code list but have many spare parts to test for a fault .
great thanks!!
Here's what I can come up with for the PJ firmware beep codes:
Short Beeps (usu. indicate mode switching / minor alert)
- ATC (Automatic Transfer Control) from AC Mains to Inverter mode --OR-- button function acknowledge
- AC Mains Voltage Too Low -> Inverter Mode
- AC Mains Voltage Too High -> Inverter Mode
Regular Beeps (usu. indicate alarm/error)
- Battery Overvoltage error
- "MOS" thermistor over temp / Output Voltage Error
- "FAN" thermistor over temp
...10 / 30. Overload Low/High
I don't see any "4-beep" trigger anywhere, which of course doesn't help identify the issue.
I ordered the controller board. i will swap it out and see what happens. I will update once the swap is complete.
Thanks,

The control board you get will probably be rev11.1 and will be different than the control board from 4 years ago . I post a photo of my rev11.1 control board in my 8kw PS inverter today and how it is wired . The rev 11.1 control board will replace rev 9.0 and rev 10.3 as wired in my 8kw and is the same wiring in my 15kw PS . I show the wiring for the rev 11.1 in my 15kw in another part of this forum and is working good . I keep the old still working rev 9.0 and 10.3 control board as spare parts .
