Well, my inverter got shorted out. I believe both 110 sides hit the neutral together. Blew MOSFETs apart, and driver board. Have replaced both, but nothing. Only one side of the MOSFET boards light up, and the driver board gets hot enough to dis-color fairly quickly. With the driver removed, still only lights up one side of the MOSFET boards, but nothing getting hot. I believe the converter board has been smokes, but it looks ok. Would anyone happen to have any insights on where to go next? Thank you.

Hmm, shorted out is all?
Yes. That is what I am told

DO you mean grid charging input and inverter output is on at the same time ?
That's what I believe happened to mine. Both 110 hit the neutral. MOSFET boards and driver board are replaced, only one side of the MOSFETs boards light green, and the new driver board gets hot fast.

NOT good seeing the FETs exploded . The heat will destroy your converter board or rev 11.3 control board needed from Powerjack . The copper trace on the mainboard may be crack or burned also . Check the mainboard for black spots . Complete mainboard with mosboard and cap is about 200 dollars .

2 questions:
- Do all FET boards light green if the driver board is removed?
- What part(s) on the driver board gets hot?
make that 3 questions, haha 😉
I am assuming the driver board heats up when the power switch is turned on. Does the control board light up as usual?

I'm trying to understand how it shorted.
This is an AMG version? You were using the universal AC output?
Was it jumpered wrong?
L1 and L2 are "110V", so you use separate neutral terminals in the 110 mode. In the 220 mode you jumper the neutrals and use the together.

I was thinking he was charging the battery with inverter grid 110v input and then switch the inverter on output 110v at the same time . There should be no grid power coming to inverter output terminal but grid power can come to the inverter input to charge the battery and the inverter output is shut off .

This is not electrically possible.
If the AC input is being utilized for charge, there WILL be AC output from said AC input.
there WILL be AC output from said AC input.
The power from the main only go to the input of inverter for charging but power from the main should not go to the inverter output terminal and a transfer switch will prevent grid power going to inverter . There WILL be AC output from the inverter AC input which is the terminal that is charging the battery . I am not sure if this is what happen to his inverter . I do not think he has a transfer switch .

Again, not electrically possible.
All the internal relay(s) in LF inverters do, is connect the AC input to the AC output. The AC output is directly connected to the transformer--so you get power pass-thru and the ability to use the same main transformer and same FETs for battery charge functionality.
HF inverters are different. But we're talking LF inverters here.
Now I am thinking maybe he was not charging the battery . He maybe backfeed the grid power back to the output of the inverter by turning on the main by accident . I do not know what happen . Why one side no LED light ? I do not think all 4 LED will be ON . IS this PJ inverter is where someone say it was working good and then I do not know what happen ? The picture look like he done a lot of work setting it up .

I have a similar inverter, and wish the guy would help us understand how it shorted. Maybe it was user error?
