Victron Energy VM-3P5A Meter – 3-Phase Energy Meter with VE.Can & Ethernet

The Victron Energy VM-3P5A Meter is a fast and versatile energy meter for single-, two-, and three-phase AC systems. It is particularly well-suited as Grid Meters in Victron ESS Systems, but it can also be used to measure PV inverters, generators, and individual AC loads.

The measured values are displayed at a high refresh rate of 100 ms recorded and via VE.Can or Ethernet transmitted to a compatible Victron GX device. This makes the VM-3P5A ideal for applications that require fast and precise power control.

Victron VM-3P5A as a grid meter in the ESS

In a Victron Energy With the Storage System, the VM-3P5A can be used as a network meter. It records the current Grid Connection and Grid Feed-in and makes these values available to the Victron system.

Measurements are taken per phase. This allows the energy flow in single-phase, split-phase, and three-phase installations to be precisely recorded and analyzed.

VE.Can and Ethernet Integrated

The Victron Energy The VM-3P5A meter offers several communication options:

• VE.Can: Two RJ45 ports for direct connection to a compatible Victron GX device.
• Ethernet: An RJ45 Ethernet port for connecting to the local network.
• Modbus UDP: Communication via Ethernet.

The energy meter can, for example, be connected to a Cerbo GX or Ekrano GX can be connected. The measured values can then be viewed on the GX device as well as in the Victron VRM Portal be monitored.

Flexible Applications

Depending on the system configuration, the Victron VM-3P5A can be used for various measurement tasks:

• Grid Meters in Victron ESS Systems
• Measuring Grid Consumption and Grid Feed-in
• Measurement of PV Inverters
• Measurement of AC Generators
• Measuring Individual AC Loads
• Monitoring of EV Charging Stations
• Monitoring Heat Pumps

External 5-A current transformers

Current is measured via External current transformers with a secondary current of 5 A. This allows the VM-3P5A to be flexibly adapted to systems of various sizes.

The information 5 A refers to the secondary current of the current transformer and not to the maximum measurable load or system current.

Measurements and Functions

The Victron VM-3P5A provides a wide range of electrical measurement and diagnostic values. These include, among others:

• Phase-to-Neutral Voltage
• Phase-to-Phase Voltage
• Phase Flows
• Neutral Current
• Power per phase
• Power Factor
• Phase Sequence in Three-Phase Systems
• Warning for Incorrect Phase Rotation
• Protective Grounding Voltages

In addition, the status LED can be configured as an energy pulse signal. Depending on the application, various calculation methods are available for energy measurement.
