How to install Victron Blue Smart IP22 charger with 3 output on a boat with 3 batteries

[jensen]

Hi

Today I have a setup as described in “Victron Marine system” on page 5:

https://www.master-instruments.com.au/files/battery_information/booklet___marine_system___en.pdf:

With a simple Voltage Sensitive Relay, such that the alternating will first charge the starter battery and the house battery.

I just bought a Victron Blue Smart IP22 charger 12V 3 outputs for my boat. I am planning to install it as described on page 14 on:

Where one output is connected to the “starter battery” and the 2th output to house battery and 3th output to thruster battery.

With this setup, the alternator will only charge “starter battery” or have I misunderstood it?

Shall I remove the Voltage Sensitive Relay?

Thanks
Morten

You need the isolator to be included. You have not misunderstood. The device is actually a FET isolator and not a voltage sensitive relay. A VSR works in a slightly different way.
