3. Installation
3.1. What's in the box?
SmartShunt | ||
Two 1.5m (59") red cables with fuse. |
3.2. Mounting the SmartShunt
The SmartShunt is rated IP21, it is not waterproof and has to be mounted in a dry location.
The SmartShunt has two 5.5 mm holes for mounting purposes located in the base of the SmartShunt. The holes can be used to screw or bolt the SmartShunt onto a hard surface (screws are not included).
For the exact location of the mounting holes see the dimension drawing in the appendix of this manual.
3.3. Connections overview
# | SmartShunt connection | Terminal type |
---|---|---|
A | LOAD MINUS | M10 bolt |
B | BATTERY MINUS | M10 bolt |
C | VE.Direct | VE.Direct terminal |
D | Aux | M10 ring terminal |
E | Vbatt+ | M10 ring terminal |
3.4. Basic electrical connections
Connection procedure:
Connect the negative battery terminal to the M10 bolt on the "BATTERY MINUS" side of the shunt. Tighten the shunt bolt with a maximum torque of 21Nm.
Note that there should be no other connections on this side of the shunt or on the negative battery terminal. Any loads or chargers connected here will be excluded from the battery state of charge calculation.
Connect the negative of the electrical system to the M10 bolt on the "SYSTEM MINUS" side of the shunt. Tighten the shunt bolt with a maximum torque of 21Nm. Make sure that the negative of all DC loads, inverters, battery chargers, solar chargers and other charge sources are connected “after” the shunt.
Note that up until 2020, the SYSTEM MINUS connection was labelled LOAD MINUS.
Connect the ferrule pin of the red cable with the fuse to the shunt by pushing the pin into to the “Vbatt +” terminal.
Connect the M10 eye terminal of the red cable with the fuse to the positive terminal of the battery.
The battery monitor is now powered up. the Bluetooth LED will start blinking and Bluetooth is active.
In order to be fully functional, the battery monitor needs to be configured; see the Configuration chapter.
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 the Configuration chapter.
3.5. 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.
3.5.1. Auxiliary connection for monitoring the voltage of a second battery
For use to monitor the voltage of a second battery, such as a starter or auxiliary battery.
Connection procedure:
Verify that the negative pole of the second battery is connected to the SYSTEM MINUS side of the shunt.
Connect the ferrule pin of the second red cable with fuse to the shunt by pushing the pin into to the Aux terminal.
Connect the M10 lug of the second red cable with fuse to the positive terminal of the second battery.
3.5.2. Auxiliary connection midpoint battery bank monitoring
For use with a battery bank that consists of multiple batteries that are wired in series or series/parallel to create a 24V or 48V battery bank.
Connection procedure:
Connect the ferrule pin of the second red cable with fuse to the shunt by pushing the pin into to the Aux terminal.
Connect the M10 lug of the second red cable with fuse to the positive terminal of the midpoint.
For more information on midpoint monitoring and for additional diagrams on midpoint battery bank wiring see the Midpoint voltage monitoring chapter.
3.5.3. Auxiliary connection for temperature monitoring
For use to monitor the temperature of a battery via the (not included) Temperature sensor for BMV-712 Smart and BMV-702 . This temperature sensor needs to be purchased separately. Be aware that this is a different temperature sensor than the temperature sensors that are included with Victron inverter/chargers and some battery chargers.
Connection procedure:
Connect the ferrule pin of the black temperature sensor wire by pushing the ferule pin into the Aux terminal.
Connect the ferrule pin of the red wire cable by pushing the ferule pin into to the Vbatt + terminal.
Connect the M10 cable lug of the temperature sensor to the positive battery terminal.
Note
Note that if the temperature sensor is used, the two red cables with fuse that came with the battery monitor are not needed. The temperature sensor will replace these cables.
3.6. GX device connection
If the system contains a GX device such as a Cerbo GX, the battery monitor can be connected to the GX device using a VE.Direct cable or a VE.Direct to USB interface.
Once connected, the GX device can be used to read out all monitored battery parameters. For more information see chapter Connecting to a GX device and the VRM portal.
3.7. Wiring for use as DC meter
When using the battery monitor as a DC meter, wire it to the device or circuit that needs to be monitored.
Note
Note that the battery monitor also needs to be configured as a DC monitor using the VictronConnect app before it will operate as a DC monitor. See the Configure for use as DC meter chapter.
It is also possible to have a main battery monitor in the system together with a separate battery monitor that has been set up as a DC meter to monitor a specific device or circuit.
