Victron VM-3P5A Energy Meter Manual 2. Introduction The VM-3P5A energy meter is a standard device to measure the power and energy of single-, split- and three-phase applications and calculates each phase's power values and broadcasts this over VE.Can or Ethernet with a high rate. It supports industry-standard 5 A current transformers (not included) and is self-powered from all phases (N-L1-L2-L3). Built-in Ethernet and VE.Can ports enable direct connection to a GX device. The energy meter works out of the box (the firmware may need to be updated; details can be found in the Firmware Updates [11] chapter) as a grid meter for systems with a MultiPlus, Quattro, Multi RS and Multi HS.
Configuration (via VictronConnect) is only required for changing the role and manual IP configuration rather than the default DHCP. Its data is displayed on a GX device such as the Cerbo GX or Ekrano GX , as well as in VictronConnect and our VRM Portal . 2.1. Features Supports industry-standard 5 A current transformers (not included) Modbus/UDP communication over Ethernet Support for 1-phase, split-phase and 3-phase configuration Configurable total energy registration: vector, arithmetic, or absolute Reports:
line-to-neutral voltage line-to-line voltage power factor (according to IEEE convention) phase sequence (for 3-phase configuration) phase rotation warning (for 3-phase configuration) protective earth voltages neutral and line currents The VM-3P5A can be configured for various roles in a GX device, such as the Cerbo GX or the Ekrano GX . Depending on the application, it can be used:
Status LED can be set as a pulse counter for quick, at-a-glance diagnostics as a grid meter, providing control input for an Energy Storage System (ESS) to measure the output of a PV inverter to measure the output of an AC genset as an AC meter to measure a dedicated AC load circuit to track an EV charger to track a heat pump It offers two options for connection to a GX device: 1. A wired Ethernet connection to the local network via the built-in Ethernet port, allowing the GX device to communicate with it. 2. A wired VE.Can connection via the onboard VE.Can port, directly linking it to the GX device. Page 2 Introduction
