Description
xVictron Energy Meter VM-3P5A
The Victron Energy Meter VM-3P5A is a three-phase energy meter designed for use with Victron GX devices. It measures AC energy flow at the grid connection point or on AC loads, giving a GX-connected system accurate, real-time visibility of import, export and consumption. It is suited to professional solar, off-grid and grid-tied installations where three-phase monitoring is required.
Key Features
- Three-phase AC energy measurement using 5 A current transformer inputs, compatible with external CTs for non-intrusive installation.
- Integrates directly with Victron GX devices (Cerbo GX, Venus GX, Color Control GX) via RS-485 Modbus communication.
- Measures both import and export, making it suitable for grid-tied systems with feed-in monitoring requirements.
- Can be configured as a grid meter, generator meter or AC load meter within the GX device interface.
- Compact and lightweight at 0.3 kg, designed for DIN rail mounting inside a distribution board or enclosure.

Product Overview
The VM-3P5A connects to a Victron GX device over RS-485 and reports real-time power, voltage, current and energy totals for each of the three phases. This data feeds directly into the VRM portal and the local GX display, giving installers and system owners a complete picture of energy flow without relying on estimates or inverter-side approximations.
The 5 A CT input design means the meter itself carries no mains current. External current transformers clamp around the live conductors, which simplifies installation and avoids the need to break the main supply cables. The meter supports multiple roles within a single system: one unit can monitor the grid connection point while a second monitors a generator or a sub-load. The GX device handles the role assignment through its settings menu.
For installers working on three-phase ESS (Energy Storage System) configurations or three-phase grid-tied systems with Victron Multi or Quattro inverter-chargers, accurate grid metering is a functional requirement, not an optional extra. The VM-3P5A provides that metering in a form that integrates natively with the Victron ecosystem.

What Is Included
- 1 x Victron Energy Meter VM-3P5A (REL200320100)
Installation Notes
The VM-3P5A must be installed by a qualified electrician. It connects to the AC distribution board via external current transformers and communicates with the GX device over a wired RS-485 connection. Correct CT orientation is required for accurate import and export readings. For grid-connected systems in the UK, the installation must comply with G98 or G99 requirements as applicable to the site. Current transformers are not included and must be sourced separately to match the site's cable size and current rating.
