Victron Energy VM-3P75CT Single and Three-Phase Energy Meter with Ethernet and VE.Can Connectivity

Energy Meter VM-3P75CT Single + 3-Phase

The Victron VM-3P75CT energy meter is a standard device to measure the power and energy of single- and three-phase applications and calculates each phases power values and broadcasts this over VE.Can or Ethernet with a high rate. It has built-in Ethernet and VE.Can ports for connecting to a GX device and the split-core current transformers enable easy and quick installation without modifying existing wiring.

The energy meter works out of the box (the firmware may need to be updated; details can be found in the Firmware Updates chapter) as a grid meter for systems with a MultiPlus and Quattro. 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 the VRM Portal.
