📝 Victron SmartShunt 300A/50mV IP21

The Victron SmartShunt 300A/50mV IP21 is a compact, all-in-one battery monitoring system designed to simplify power management in caravans, boats, 4WDs, and off-grid setups. It eliminates the need for a display—your smartphone or tablet becomes the monitor through the VictronConnect app. This intelligent device provides accurate readings of state of charge, time to go, voltage, current, and battery history, helping users optimise battery performance and extend battery life.

⭐ ESSENTIAL BENEFITS

• Simplified battery monitoring – no display required; view all data via the VictronConnect app.
• Full power insight – track charge level, remaining runtime, voltage, and current in real time.
• Compact, clutter-free design – replaces traditional monitors for clean and efficient installations.
• GX device compatibility – connect to Cerbo GX or Color Control GX using the VE.Direct port.
• Flexible auxiliary input – can monitor a second battery, midpoint, or temperature sensor.
• VE.Smart networking – shares live data with Victron chargers for optimal charging efficiency.
• Improved battery lifespan – alerts you to deep discharges, undercharging, or overcharging before they cause damage.

⚙️ HOW IT WORKS

The SmartShunt sits in the negative battery line, measuring current and voltage to determine the state of charge and time to go. Data is transmitted via Bluetooth to the VictronConnect app or through VE.Direct to a GX device for integration with the VRM portal. The auxiliary input can be configured to track a second battery voltage, midpoint, or temperature.
