The Victron Energy Meter EM24 Ethernet is a precision three-phase energy counter designed to measure power, current, and voltage across your electrical distribution network.
The Victron Energy Meter EM24 Ethernet (MPN REL200200100) is a highly precise instrument engineered for comprehensive power and energy measurement in three-phase electrical systems. Designed specifically to integrate with the Victron energy management ecosystem, this meter reads and tracks system metrics at the main distribution board or at specific AC sources. By delivering real-time telemetry, it allows your energy storage system to adapt dynamically to load demands, optimise self-consumption, and accurately record structural energy flows.
Once deployed within an electrical network and linked to a centralized Victron GX device (such as the Cerbo GX or Ekrano GX), the EM24 Ethernet can be configured to fulfil one of four distinct operational profiles via the Venus OS interface:
The standout feature of this specific EM24 variant is its native RJ45 Ethernet interface. Unlike standard RS485 meters that mandate a dedicated physical data cable or specialized Zigbee wireless bridges directly to the GX device, the EM24 Ethernet communicates natively over your local area network (LAN). This setup proves invaluable when the main utility meter box is located far from the inverter and battery storage array; the device simply utilizes existing network infrastructure to stream data registers securely over Modbus/TCP, ensuring ultra-reliable data delivery with a 600ms refresh cycle.
The unit features a clear, permanently integrated front-facing LCD screen that allows onsite installers to verify live operational parameters—including active power, voltage, current, and power factor per phase—without requiring software access. Housed in a standard compact DIN-rail mount enclosure, it utilizes robust screw terminals to handle direct feed-through currents up to 65A per phase, eliminating the space constraints and auxiliary wiring typically associated with external current transformers (CTs).
