Victron SmartShunt 500A/50mV — SHU050150050

The Victron SmartShunt 500A/50mV is a standalone battery monitor that measures state of charge, consumed amp hours, and voltage without requiring a dedicated display unit. It connects directly to the VictronConnect app via Bluetooth, making it a practical choice for installers and off-grid system builders who need accurate battery monitoring without the cost or complexity of a full BMV monitor.

Key Features

• 500A continuous current rating with a 50mV shunt drop, suitable for most 12V, 24V and 48V battery banks.
• Built-in Bluetooth connects to the VictronConnect app on iOS and Android for real-time monitoring and configuration.
• Monitors state of charge (%), consumed amp hours, voltage, current, power, and time remaining.
• Supports a wide range of battery chemistries including lead-acid (AGM, gel, flooded) and lithium (LiFePO4).
• Compact, shunt-only form factor replaces the need for a separate display, reducing installation space and cost.
• Configurable charge efficiency factor, Peukert exponent, and tail current settings for accurate SoC tracking across different battery types.
• VE.Direct port allows integration with Victron GX devices, MPPT solar charge controllers, and other compatible equipment.

Product Overview

The SmartShunt functions as the measurement core of a battery monitoring system. The 50mV shunt drop at 500A gives the device a precise reference for calculating current flow in and out of the battery. This data is processed internally and transmitted over Bluetooth to VictronConnect, where users can view live readings, review historical data, and adjust monitoring parameters. No separate display unit or control panel is required, though one can be added if needed.

The VE.Direct port is a significant practical advantage. It allows the SmartShunt to feed battery state-of-charge data into a Victron GX device (such as a Cerbo GX), making it visible on the VRM portal and usable by other devices in the system for load shedding or generator start logic. This makes the SmartShunt a cost-effective entry point into a fully integrated Victron monitoring ecosystem.

Accurate state-of-charge tracking depends on correct configuration. The SmartShunt allows adjustment of battery capacity, charge efficiency factor, Peukert exponent, and the tail current threshold used to detect a full charge. Taking time to configure these parameters correctly for the specific battery bank will significantly improve the reliability of the SoC reading over time.

Technical Specifications

Applications

• Off-grid solar systems requiring battery state-of-charge monitoring without a dedicated display panel.
• Marine and narrowboat installations where panel space is limited and Bluetooth monitoring is preferred.
• Motorhome and campervan leisure battery banks with 12V or 24V systems.
• Victron-based systems using a Cerbo GX or other GX device, where the SmartShunt feeds SoC data via VE.Direct.
• Retrofit monitoring on existing battery banks where a full BMV monitor is not required.

What Is Included

• Victron SmartShunt 500A/50mV unit
• VE.Direct cable
• Connection cable for battery negative
• Documentation and quick-start guide

Installation Notes

The SmartShunt must be installed in the negative battery lead, between the battery negative terminal and all other negative connections in the system. All negative return currents must pass through the shunt for accurate measurement. Incorrect wiring, such as bypassing the shunt with a direct chassis ground, will produce inaccurate readings. Installation should be carried out by a qualified electrician or experienced installer familiar with DC battery systems. For systems integrated into a solar PV installation, a qualified or MCS-accredited installer is recommended.
