Hi all
My parents have a 3-phase system 3 using multiplus 1200 units. This was installed back in 2014 and was running without any problem. We’ve just replaced the battery bank and have encountered a problem. One of the units blew the fuse on the 12v supply, we’ve changed this and now we have the alarm light lit on the other units. I’ve read the manuals but can’t find this issue discussed, I’ve spoken to a local Victron installer but as they didn’t do the install they don’t want to look at it!
Any help would be greatly appreciated
