Found burned components on mpp 2424lv. Looking for schematics.

[BMWAirhead]

My mpp 2524lv stopped charging from PV panels. I did some disassembly looking for fuses and found this, a few burned diodes. Now I’m looking for schematic diagrams so I can replace components. Any help appreciated.

Can’t read the silkscreening on component so going to need schematics or someone with a similar one to tell you what it is.

I reported to MPP and they sended the whole PCB; same one as yours.

Did they cover under warrantee? If not, how much did replacement cost you, thanks.

No it was under warranty, but i dont think it would be too expensive to ask for the new PCB, as i think it would be hard to get the schematics on this specific unit.

Do you know why yours failed? In my case I think it was because a breaker to the battery disconnected battery while PV panels were connected.

Not sure, i was doing parallel connection with another unit and maybe i did something wrong, do you have an error code with yours?
