Hie there
Am new to electronics repairing, I need your help.
My off grid inverter blew 2 out of 4 mosfets from the Ac side and I replaced with new ones and worked fine that was 5 months ago.
Now it did the same this time with some resistors near the mosfets burnt . I checked for other failed components but only 4 resistors 2×100ohms 2×4.7 ohms. I replaced all burnt componets still can't work. Showing error code 05 (output short circuited) but when I turn it on while I touch source and drain of the other transistors with DMM probes set on diode check or resistance check with DMM on regardless of polarity , it works fine.
Help.
