Hi, I'm wondering if anyone know how to trouble fault this SMA Sunny Boy SB 2500.
I know nothing about this unit, it was bought as spares or repair. I dont even know how to set it up, but this is what I've done so far. ( Not a Lot) lol
I plugged in a solar panel, Plugged in some kind of disconnect and supplied 240v ac and nothing is coming up on the display.
I've checked there is 240v going to the board, I don't know where it goes after that, I also cant see any fuses except the big fuse by the solar input which checks ok.
The unit is consuming 20 watts.
