Hello,
I had a bad experience with my "easun 3kva mppt ... " wich seems to be the same hardware as axpert VM II series. After a rain with lot of lightnings my inverter went off with warning "20" ont its display. The error isn't in the manual.
It does not start anymore, but I searched for problems and found 2 faulty boards.
1. the communication board ( D2 burned ) PN:16-500900-00G
2. the CNTL Board PN:16-501053-00G
Please let me know if anyone could help me buy this boards ( especially the CNTL Board ) because I can't use the inverter anymore.
I am from Romania but I am willing to pay for shipping without problem.
Thanks a lot for your future support.
