Wiring diagram bmv712 and blue smart charger

Hello all,

I bought a new boat. In this boat we have an old charger and a analoge voltage meter. As a winter project I upgraded the charger and voltage meter to an Victron Blue Smart Charger IP22 12/20 (3) and a BMV-712.

As in most older boats the electrical system is a mess and I want to clean it up as much as possible.

I've got an household battery and a starter battery. My question for now is.... Is the wiring diagram which I made correct? Or is there still a problem.

In the current situation the negative lines of both the batteries are connected to the most left positioned switch. I understand this needs to be changed if I place the BMV712 in my boat.


Kind regards,

Koen de Kruijf

Never turn the negative isolator off with engine running fuses in the alternator line and the battery cables Anyway this is a very ruff rehash of your diagram
