Victron 2000A/50mV-0.5 / 3xM10 Shunt

Victron 2000A/50mV-0.5 / 3xM10 ShuntHigh Capacity Current Measurement for Heavy Duty DC Systems When building or upgrading a large scale power system, accurate battery monitoring is critical. Standard battery monitors typically include a 500A shunt, which is perfectly adequate for everyday recreational vehicles and smaller off grid setups. However, when you introduce high output inverters, massive battery banks, or heavy industrial DC loads, exceeding that threshold becomes a real risk.

High-Capacity Current Measurement for Heavy-Duty DC Systems

When building or upgrading a large-scale power system, accurate battery monitoring is critical. Standard battery monitors typically include a 500A shunt, which is perfectly adequate for everyday recreational vehicles and smaller off-grid setups. However, when you introduce high-output inverters, massive battery banks, or heavy industrial DC loads, exceeding that threshold becomes a real risk. Upgrading to a high-capacity 2000A shunt ensures your monitoring equipment can safely handle massive current flows without compromising accuracy or creating a dangerous bottleneck in your electrical system.

Precision Engineering for Accurate Battery Tracking

At the core of this unit are precision resistive plates designed to create an exact 50mV drop at a 2000A load, featuring an impressive 0.5 percent tolerance. This highly linear millivolt signal is essential for advanced battery monitors to calculate state of charge, current draw, and historical data with pinpoint accuracy. Whether you are discharging heavily into a massive inverter setup or receiving a rapid influx of charge from a large solar array, your monitor will receive clean, reliable data.

Robust Construction and Thermal Stability

Handling up to 2000 Amps requires serious hardware. This shunt features oversized solid brass conductor blocks that provide exceptional electrical conductivity and thermal mass. This design efficiently dissipates heat, drastically reducing the risk of thermal failure or resistance shifts during sustained heavy loads. The entire assembly is mounted to a rugged, non-conductive black base with pre-drilled holes, allowing for safe and secure installation directly to a bulkhead, chassis, or electrical board without the risk of grounding out.

Key Features and Specifications

• Massive 2000A Capacity: Safely handles extreme continuous and peak DC loads in large-scale power systems.
• 50mV Output with 0.5% Tolerance: Delivers an ultra-precise voltage signal for accurate state of charge and current tracking.
• Solid Brass Conductor Blocks: Maximises conductivity while effectively managing heat under heavy electrical stress.
• Multiple M10 Connections: Features six heavy-duty M10 threaded studs (three per side) to accommodate massive cable lugs and parallel heavy-gauge wiring.
• Dedicated Sensing Screws: Top-mounted screws allow for quick and secure connection of voltage sensing or monitor wires.
• Insulated Mounting Base: Protects against accidental shorts and provides a stable platform for heavy cable terminations.

Optimised for Large-Scale Cabling

A common challenge in high-current DC systems is terminating multiple large cables securely. This unit addresses that problem by providing three M10 threaded studs on each side of the brass blocks. This multi-stud layout allows you to distribute massive cable lugs across a wider surface area, minimising contact resistance and eliminating the need to stack too many terminals on a single post.

Seamless Integration with Battery Monitors

This unit is the ideal upgrade for users looking to expand the capabilities of their existing Victron BMV battery monitors or similar programmable current monitoring devices. By simply swapping out your existing standard shunt and updating the shunt settings in your monitor's configuration menu to reflect the 2000A/50mV rating, you instantly unlock the ability to measure significantly larger current flows. It is widely used in commercial marine vessels, large off-grid solar storage systems, and industrial backup power applications.
