Aims Power PWRINV500048W Inverter - No Power - So Much Carnage! Part 1 of ?

Here is another Aims Power PWRINV500048W Inverter sent to me from Stockton, Ca with the complaint of "DEAD". This is the initial diagnosis and estimate stage. As of now I have found 13 out of 16 DC input 10 amp fuses blown open with some really weird arcing across most of the blown fuses. I did estimate to replace all 32 DC-DC driver FETs as well as all 8 of the DC-AC output FETs. Once again this is just the estimate stage. If the customer approves the estimate you will see a part 2 in a future video.
