The Victron Energy Meter ET340 is a three-phase energy meter designed for demanding installations, capable of accurately measuring electricity consumption, photovoltaic production and exchanges with the grid up to 65 A per phase. Thanks to its Modbus RS485 communication and native compatibility with Victron GX systems, it enables real-time energy monitoring, optimisation of self-consumption and better management of energy flows. Its DIN rail format and direct measurement without current transformers make it easy to install in residential, commercial and industrial environments.

Victron Energy Meter ET340 - Three-phase meter for photovoltaic systems


The Victron Energy Meter ET340 three-phase energy meter
is designed to accurately measure consumption, production and exchanges of electrical energy on a three-phase network. It is particularly well suited to photovoltaic, industrial and tertiary installations and enables reliable monitoring of energy flows in order to optimise self-consumption and grid management.






Key features
