Description
xVictron Energy Shunt 2000A/50mV (3xM10)
The Victron Energy 2000A/50mV shunt is a high-current DC measuring shunt designed for use in large battery systems, off-grid installations and commercial energy storage applications. It allows accurate current measurement by producing a calibrated 50mV signal at full rated current, which can be fed into a battery monitor or energy management system. The three M10 connection points accommodate heavy-gauge cabling suited to high-amperage DC circuits.
Key Features
- Rated at 2000A continuous DC current with a 50mV full-scale output signal, giving a shunt resistance of 0.025 milliohms.
- Three M10 bolt terminals provide secure, low-resistance connections for large cross-section cables.
- Compatible with Victron BMV battery monitors and other shunt-based monitoring equipment that accept a 50mV input.
- Solid construction with a weight of 2.15kg, reflecting the heavy-duty busbar and resistive element required at this current rating.
- Suitable for use in battery banks, DC distribution boards and large inverter or motor drive installations where accurate current measurement is essential.

Product Overview
A shunt works by inserting a known, very low resistance into the DC circuit. The voltage drop across that resistance is directly proportional to the current flowing through it. At 2000A, this shunt produces exactly 50mV, which is the standard signal level accepted by most battery monitors and data loggers. The measurement is passive and does not require a separate power supply, making it straightforward to integrate into existing monitoring wiring.
At 2000A, cable sizing, terminal torque and busbar layout all become critical. The three M10 terminals allow the load and source cables to be distributed across multiple connection points, reducing localised heating and mechanical stress on any single terminal. This is particularly relevant in systems where multiple battery strings or inverters share a common measurement point. The shunt should be positioned as close to the battery negative terminal as practical to capture all current flows in the circuit.
The 50mV output is a widely adopted standard. If you are using a Victron BMV-700, BMV-712 or SmartShunt, this external shunt allows you to extend measurement capability beyond the built-in 500A shunt supplied with those monitors, covering large-scale systems that would otherwise exceed the internal shunt's rating.

- Marine and vehicle installations with high-capacity lithium or lead-acid battery systems.
- DC distribution boards in large solar PV systems feeding multiple inverters or loads.
- Retrofit current monitoring on existing installations where no shunt is currently fitted.
What Is Included

Installation Notes
This shunt carries the full DC current of the system and must be installed by a qualified electrician or experienced DC systems installer. At 2000A, incorrect cable sizing, inadequate terminal torque or poor busbar connections present a serious risk of overheating or fire. The shunt should be mounted on a non-conductive surface or properly insulated busbar assembly. Ensure all connections are made with appropriately rated lugs and that the 50mV sense wiring is routed separately from power cables to avoid interference. For systems connected to the grid, all relevant UK wiring regulations (BS 7671) apply.
