Multiplus II 48V 3000W - Damaged Interference Suppression Capacitor

isc.jpegpcb-view-4.jpegpcb-view-3.jpegpcb-view-2.jpegHello,

Please help me understand whether replacing the capacitor MKP62 305~X2 225K 40/110/56/B can restore this inverter. The capacitor was damaged by a short circuit on AC IN during heavy downpour accompanied by several lightning strikes.

The adjacent toroidal inductor sparks and the inverter goes to error mode.

The fuse is ok and the line has continuity.

Any top and underside PCB photos of undamaged inverter for reference will be highly appreciated.

Sample photos attached.pcb-view-1.jpeg

Thanks

Lawrence

It is a multi layer board so replacing that one part will not help you.

Also with lightning can possibly be other issues - speaking from experience.

It would be better for you to take it into a Victron service or repair center, get the board replaced and the unit tested incase the power pack also has issues. It may be possible for them to send you a board all you can do is ask.

Sorry it is not better news. Lightning is a funny thing, you may get away with just one board replacement. If it is for a client, I would have all the boards replaced if the transformer is ok, just for reliability.

That is quite significant damage. The PCB its self is damaged too badly. The is a big hole right the way through it!
There is no point in replacing components. Even if you exchange every single component on the board, the PCB will still have that damage, so better to get a new PCB assembly.
