The battery monitor needs to be configured to be fully operational, for that see chapter Configuration [8] .
In case the battery monitor is going to be used to monitor a second battery, battery bank midpoint or battery temperature, see one
of the next 3 paragraphs on how to do this and then go to chapter
Configuration [8] .
3.3.1. Battery minus connection
Connect the negative of the battery to the M10 bolt on the “BATTERY MINUS” side of the shunt.
Note that there should be no other connections on the “BATTERY MINUS” connection of the shunt. And similarly, there should be
no other connections on the battery negative. Any loads or chargers here will not be included in the battery state of charge
calculation.
3.3.2. System minus connection
Connect the negative of the electrical system to the M10 bolt on the “SYSTEM MINUS” side of SmartShunt. Make sure that the
negative of all DC loads, inverters, battery chargers, solar chargers and other charge sources are connected “after” the
SmartShunt: on the SYSTEM MINUS (*) connections.
(*) Up until 2020, the SYSTEM MINUS connection was labelled LOAD MINUS.
3.3.3. Vbatt connection
Connect the M8 terminal of the red cable with fuse to the positive terminal of the battery
Connect the ferrule pin of the red cable with fuse to the SmartShunt by pushing the pin into to the “Vbatt+” terminal.
As soon as the fuse is placed in the cable, the SmartShunt Bluetooth will
start blinking. The SmartShunt is now active. The next step is to set up
with the VictronConnect App. This is explained in chapter 4:
“Commissioning”.
In case the Aux port is going to be used for monitoring a second battery,
midpoint or temperature, see one of the next 3 paragraphs on how to do
this and then go to chapter 4: “Commissioning”.
3.4. Auxiliary electrical connections
In addition to the comprehensive monitoring of the main battery bank, a second parameter can be monitored. This can be one of
the following:
• The voltage of a second battery, like a starter battery.
• The midpoint deviation of the battery bank.
• Battery temperature.
This chapter describes how to wire the Aux terminal for the three above options.
3.4.1. Auxiliary connection for monitoring the voltage of a second battery
The Aux terminal can be used to monitor the voltage of a second battery, such as a starter battery.
