The Victron Energy Meter VM-3P75CT (REL200300100) from Nomadic Supply Company® is a standard device to measure the power and energy of single- and three-phase applications and calculates each phase’s 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 Victron Energy Meter VM-3P75CT (REL200300100) 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.
Victron Energy Meter VM-3P75CT (REL200300100) Features:
- Three-Phase Energy Monitoring. Measures voltage, current, power, and energy on all three phases for complete AC system visibility.
- 75A Current Transformers Included. Ships with three 75A split-core CTs for non-invasive installation on existing wiring without disconnecting circuits.
- GX Device Integration. Connects directly to Victron GX devices for centralized monitoring of grid, shore power, and generator AC inputs.
- Bidirectional Measurement. Detects both power consumption and feed-in for grid-tied and hybrid solar installations.
- DIN Rail Mounting. Standard DIN rail form factor for professional installation in electrical distribution panels and switchboards.
