SmartShunt 300A

The SmartShunt 300A is an all-in-one battery monitor designed to track your battery's status without requiring a dedicated display. It sends data to your smartphone or tablet via the VictronConnect app, turning your mobile device into a battery dashboard.

The SmartShunt 300A can display several essential battery parameters, including state of charge (SoC), remaining time before full discharge, voltage, current, as well as detailed historical data.

No, the SmartShunt 300A does not have a built-in display. It is designed as a discreet battery monitor, using your smartphone or tablet as a display via the VictronConnect app connected via Bluetooth.

The SmartShunt 300A operates on an input voltage range from 6.5 VDC to 70 VDC.

The current consumption of the SmartShunt 300A is very low, less than 1 mA.

The SmartShunt 300A can monitor batteries with a capacity ranging from 1 Ah to 9999 Ah.

The SmartShunt 300A provides measurement accuracy of ±0.4% for current and ±0.3% for voltage. State of charge is measured with an accuracy of ±0.1%.

You can access SmartShunt 300A data in two main ways:

Via the VictronConnect app on your smartphone or tablet, connected via Bluetooth.By connecting it to a Victron Energy GX device (such as a Cerbo GX) via a VE.Direct cable.

Yes, the SmartShunt 300A is compatible and can be connected to a Victron Energy GX device via a VE.Direct cable for centralized integration and management of your energy system.

Yes, an optional temperature sensor (part number ASS000100000) can be connected to the auxiliary input of the SmartShunt 300A to monitor battery temperature. The measurement range is -20 to +50°C.

Yes, the auxiliary input of the SmartShunt 300A can be used to monitor the voltage of a second battery, with an input voltage range of 6.5 VDC to 70 VDC.

The SmartShunt 300A is an alternative to the BMV-712, offering the same battery monitoring functions but without a dedicated display, programmable visual and audible alarms, or a programmable relay. It is designed for systems where simplified wiring and reduced footprint are preferred.

Yes, the SmartShunt 300A is compatible with lithium batteries. For optimal monitoring, it is recommended to set the charge efficiency factor to 99% and Peukert’s exponent to 1.05 in the VictronConnect app.

The Bluetooth signal has a typical range of 10 to 15 meters. However, conductive elements such as a vehicle’s metal chassis or seawater around a boat hull can reduce this range. If the range is insufficient, it is possible to add a VE.Direct Bluetooth dongle (ASS030536011) and disable the SmartShunt’s internal Bluetooth.

The SmartShunt 300A box contains the SmartShunt itself and two cables with a 1A fuse. These cables are for connecting the positive terminal and the starter battery or mid-point.

For the basic installation, you will need appropriate battery cables to connect the SmartShunt between the battery's negative terminal and the DC system's negative terminal. A VE.Direct cable is not included if you wish to connect it to a GX device.

For a basic installation, connect the negative terminal of your main battery to the BATTERY MINUS terminal of the SmartShunt. Then, connect the negative terminal of your DC electrical system to the SYSTEM MINUS terminal of the SmartShunt. Finally, connect a power cable between the positive terminal of the battery and the Vbatt+ terminal of the SmartShunt.

The SmartShunt 300A has compact dimensions of 44 mm (height) x 120 mm (width) x 44 mm (depth).

The connection bolts for the SmartShunt 300A shunt are M8 size.

The SmartShunt 300A has an IP21 protection category, meaning it is protected against solid objects larger than 12.5 mm and against vertically falling water droplets.
