Reverse polarity

I recently visited norway and a couple of thimes connected the 220 volt supply wrong which gave me reverse polarity warning on my sargent power supply unit. I have come away and my solar has stopped working. Could this have blown my 100/20 mppt controler?



Thanks

Some screen shots of the controller operating from victron connect would help a lot.

Hello @Daftladharry , the solar controller is isolated from the mains input to your system. It is hard to comment on a system that is not described in detail but it would be very unusual if reverse mains polarity could be associated with a problem with the solar controller.
