Hello,
I have a smartpi that has been operating successfully since april 2018 but yesterday 2 of the 3 varistors have blown up with as result that the main switch of the grid input also tripped.
(I have put a link to some pictures)
Is it possible to get the schematic of the voltage input circuit?
I would like to investigate the possible cause of this failure.
Regards,
Lieven
