Product description

The SmartShunt is an all-in-one battery monitoring solution that offers a more budget-friendly alternative to the Victron BMV series of battery monitors. The SmartShunt monitors parameters like state of charge, remaining time, temperature, historical information and much more. The device does not feature a built-in LCD display, instead monitoring is provided through the VictronConnect software, available on the most popular desktop and mobile operating systems. Simply pair your device to the SmartShunt using its integrated Bluetooth connectivity, or use a VE.Direct to USB interface. The SmartShunt is fully compatible with Victron GX devices such as the Cerbo GX, Cerbo-S GX etc.

Additional specifications and description

Why is battery monitoring necessary?
Unlike a fuel tank, it is impossible to easily estimate how “full” a battery is, a properly configured battery monitor is required.
What’s more, there are multiple factors that can permanently damage a battery, or reduce its useful life significantly, such as over discharging, overcharging, excessive charge/discharge currents, excessively high ambient temperatures etc. The SmartShunt, in addition to providing useful estimates such as state of charge and approximate runtime, helps ensure that the battery is used in an appropriate (for the specific battery chemistry) manner, prolonging its service life.

The Victron SmartShunt is a robust, versatile, high-precision battery monitoring solution for energy storage systems, using batteries without an integrated BMS.
It measures battery voltage and current, and based on these measurements, it calculates the battery's state of charge and remaining time until empty. It also keeps track of historical data, such as deepest discharge, average discharge and the number of charge and discharge cycles.
A connection with the VictronConnect app is possible via Bluetooth or USB. The VictronConnect app can be used to read out all monitored battery parameters or to change settings. To connect via USB, an optional VE.Direct to USB interface is needed.
If the battery monitor is connected to a GX device, such as the Cerbo GX or the ColorControl GX, the battery can be monitored locally with the GX device or remotely via the VRM portal.
The auxiliary input can be used to monitor the voltage of a second battery or the midpoint of a battery bank. The auxiliary input can also be used for battery temperature monitoring, together with the optional Temperature sensor for BMV.
When connected to other Victron products via VE.Smart networking, the battery monitor can provide real-time battery data such as battery voltage and current via Bluetooth for use by Victron solar chargers and select AC chargers.

System integration considerations
Depending on the system configuration, it may be necessary to add additional accessories, which are purchased separately.
Temperature monitoring - to measure the battery temperature a Victron Temperature sensor for BMV is required.

Remote monitoring via a GX device such as the Cerbo-S GX/Cerbo GX, requires a cable to connect the two devices – either a VE.Direct cable or VE.Direct to USB interface.
The VE.Direct to USB interface can also be used to connect the SmartShunt to a Windows PC and use VictronConnect to configure it.

Systems with multiple batteries - for such systems
it might be prudent to add a Victron Battery Balancer.
As its name suggests, the function of the Battery Balancer is to equalise the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24V battery system increases to more than 27.3V, the Battery Balancer will turn on and compare the voltage over the two series connected batteries. The Battery Balancer will draw a current of up to 0.7A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge. If needed, several balancers can be paralleled. A 48V battery bank can be balanced with three Battery Balancers, one between each battery.
