My Multiplus 2 has started tripping the supply 40A power breaker, in full mode or charger only mode. The only connection is to the AC IN, no load. It had previously been working OK. At power on the mains light comes up, but when the internal relay operates the breaker trips. Any ideas?
What about the connection to the battery?
Maybe a blown fuse?
There are two breakers, 32A type B mcb on a ring final circuit in the workshop where the Multi is plugged in, fed from a 40A type B mcb on the house consumer unit. Both trip when the Multi relay pulls in. I was running it without this problem the day before, so it makes me suspect the Multi, as I'm not aware of any other changes.
Oh, yes, I'm in the UK.
