Victron Energy Meter VM-3P75CT Three-Phase 75A

Victron VM-3P75CT Three-Phase Energy Meter

The Victron VM-3P75CT is a highly accurate, dedicated energy meter designed to measure the power and energy flow of your entire electrical system. Well suited to complex Energy Storage Systems (ESS), this three-phase meter is typically installed at the main distribution box to track grid imports and exports. By precisely measuring energy flow, it allows the broader system to minimise grid reliance and optimise the use of solar or battery power.

It can also be deployed to measure the output of a specific PV inverter or dedicated AC loads, providing highly granular data for your monitoring platform. Whether you are running a grid-tied residential solar array or a demanding commercial backup system, the VM-3P75CT provides the real-time data required to efficiently manage load distribution.

Simplified Installation with Split-Core CTs

One of the major benefits of the VM-3P75CT is its non-invasive installation process. Rather than requiring you to disconnect heavy mains wiring to pass cables through the meter, it is supplied with split-core current transformers (CTs). These clamps simply snap over existing wiring, greatly reducing installation time and the complexity of retrofitting the device into established electrical switchboards. The supplied CTs are designed to accurately measure currents up to 80A per phase, accommodating typical domestic and light commercial systems.

Advanced Connectivity via Ethernet and VE.Can

Modern energy systems rely on rapid data transmission to respond to fluctuating grid loads. The VM-3P75CT calculates root mean square (RMS) power values for each phase and transmits them at a high refresh rate over a local network. By connecting via Ethernet to your local area network, or via the integrated VE.Can port directly to a GX device, the meter ensures the system receives critical data with minimal latency.

When connected to a Victron GX device, such as the Cerbo GX or Ekrano GX, all data is elegantly displayed on the local dashboard. This information is also seamlessly uploaded to the free Victron Remote Management (VRM) portal, allowing operators to monitor AC loads, grid interaction, and PV output remotely.

Key System Features

• High Refresh Rate: Calculates RMS power for each phase rapidly to ensure highly responsive ESS control.
• Dual Communication Ports: Features both VE.Can and Ethernet for flexible integration into new or existing networks.
• Non-Invasive Setup: Supplied with split-core current transformers that clip directly over existing wiring without disconnection.
• High Measurement Range: Safely measures up to 80A per phase across three-phase or split-phase architectures.
• GX Device Integration: Designed to display real-time energy flow data on the Cerbo GX, Ekrano GX, and the VRM portal.

Designed for the Victron Ecosystem

Managing an efficient ESS requires precise communication between all components. The VM-3P75CT operates as the central sensory node for your distribution box. By continuously feeding load data to your inverter chargers and control modules, it helps prevent unnecessary grid draw and ensures battery reserves are allocated where they are needed most.

Adding this three-phase energy meter into a Victron installation provides a complete overview of your energy generation and consumption. Designed specifically for integration with advanced solar and battery ecosystems, the Victron VM-3P75CT is a reliable solution for gaining total control over your power management.
