The Victron ET340 is a standard device to measure the power and energy of a 3-phase application, for example at the distribution box or to measure the output of a PV Inverter, AC Genset or the output of an inverter and inverter/charger. Its data will be displayed on a GX device and our VRM portal.

The ET340 can be configured for four different roles in a GX device such as the Cerbo GX:
As a Grid meter and used as control input for an ESS System.
To measure the output of a PV Inverter.
To measure the output of a AC Genset.
As a AC meter to measure the output of an inverter or inverter/charger.

It offers two options for connection to a GX device:
A wired connection, either by using the RS485 to USB interface with 1.8m or 5m cable length.
A wireless connection via our Zigbee to USB and Zigbee to RS485 converter.
