My current understanding is when parallel or 3 phase connection of Multiplus or Quattro inverters, requires the negative terminals to be connected at all times and can't be broken. ie run through a CB or fuse/disconnector.
Problem is to be compliant in Australia as per AS5139 standards all PCE must have a CB or Fuse/ disconnector on both the negative and positive supplies of each PCE. Note Victron manual indicates in this event to post a sign indicating to home owner on shutting down system to remove communications cable prior to opening CB. All good until the CB operates in anger.
Under my understanding then we can't operate victron's in parallel or 3 phase.????? If anyone has a way around this issue, please comment.
Cheers
