Victron Energy ET340 Energy Meter | 3-Phase, 65A/Phase

The Victron Energy ET340 Energy Meter is a direct-connected, three-phase meter for measuring power and energy at up to 65A per phase. Model ET340 / REL300300000 installs on a DIN rail and uses RS485 Modbus communication to send measurement data to a compatible Victron GX device.

In a Victron system, the meter can serve as an ESS grid meter, monitor a PV inverter or AC generator, or measure a dedicated AC load circuit. Data is shown locally on the GX interface and remotely in the VRM Portal. Wired RS485-to-USB or supported Zigbee connections provide flexible system integration. The compact, self-powered design supports clean fixed installation in electrical panels.
