I have a multiplus 12/3000 that goes straight to 'overload' when a battery is connected, I've sent it to a dealer who said it's non repairable as Victron doesn't support products over 10 years old which IMO is a bit poor as you pay a premium in the first place and no spares are accessible to the consumer themselves.
Anyway am i stuck with it as a paperweight or are there any independent companies (UK based) that could breathe some life into it
Thanks
