The ET340 (for up to three phase max. 65A) energy meters are typically used in an energy storage system.
Energy meters are normally used in an energy storage system, to measure the power and energy of the entire application at the distribution board. The energy meters can also be used to measure the output of a PV inverter, the Inverter, to display the data on a GX device such as the Cerbo GX and the VRM portal.
With the ET340 three-phase energy meter (kWh), dual tariff management is possible for active energy metering and cost allocation. The meter can measure incoming and outgoing energy or be programmed for either.
The ET340 enclosure is for DIN rail mounting and features an RS485 Modbus port available via screw terminals, dual RJ45 connectors or optical infrared communication port for up to 247 transceivers on the same bus. An operating hours counter is also available to link the energy to the relevant working hours.
