Hello All,
My 15Kw inverter went overheated, blew up several mosfet boards. I all mosfet boards, and the driver board. Now, when I turn it on, the two LED screen came on, no voltage display, and keeps beeping. Can someone give some directions on how to solve this problem? Many thanks in advance.
Cheers,
Tung
Depending on the time frame of the warranty coverage you maybe get some free replacements parts, otherwise you will have to give more cash to Mr jack to replace those mosfets boards , the main and driver board. These parts are fairly easy to replace ( no soldering necessary) by the way those mosfets LED indictor are cosmetic they are alway on with burnt mosfets.
Thanks for your reply. All mosfet boards are new. This inverter infact I bought it Sean from Genetry Solar a few years ago when he was working Power Jack. the first day I installed it, accidentally reversed the L1 and N. I have been trying contact Sean to pay to repair it, but he never reply my call or email. I replaced the mosfet boards and the driver. When I turned on, everything seemsed ok. It keeped beeping. It would be nice to have it fixed.
The thing is PowerJack inverter is affordable, but it is not reliable. All other inverter are expensive that was why bought it from him. If I can get another brand that is more affordable, I would dump this inverter. Thanks again for your input.

MY 15kw is the same as yours but was rebuilt with the ASL9.0 transformer and has the rev 10.3 rev board . I have been using for 3 years and iis very reliable sometime running 24/7 . I email Sean email many times and he never answer . I can fix your inverter with the rev 11.3 control board amd a complete main board . Powerjack no longer make any of the parts in your and mine inverter so the parts has to come from China . I done this and can run a 4 ton heat pump for 1/2 hour now . The main board has FETs that is lot better than 3 years ago and it never blow up so far .

Sean no longer handles Power Jack service--not only has he not been compensated for quite some time for providing service, he also does not have any of the new parts, nor any "new" units to base repair information off of. And there is a limit to how much one person can handle as far as responding to everything--plus living.
