The Victron EnergyMeter ET112 is a single-phase energy meter measuring AC energy flow at up to 100A. It connects to Victron GX devices for real-time monitoring of grid consumption, solar production or generator output.

Victron ET112 key features

• Single-phase AC energy measurement rated up to 100A
• Works with Victron GX devices including Cerbo GX, Color Control GX and Venus GX
• Measures bidirectional energy flow for grid import/export or PV production metering
• Communicates via RS-485 Modbus, connecting to the GX device's VE.Can or USB port through a suitable interface
• DIN rail mounting, weighs 0.15 kg
• Reports live power, voltage, current and cumulative energy (kWh) through the GX interface and VRM portal

How it works

The ET112 connects to a GX device over RS-485 Modbus via a USB to RS-485 interface. Once configured, it reports live power data so the GX device can adjust inverter/charger output based on actual grid import or export figures. In an ESS installation it is typically placed at the grid connection point. It can also monitor a PV inverter that lacks native Victron communication support. The 100A rating suits most single-phase residential and light commercial connections.

Applications

• Grid import/export monitoring in Victron ESS installations
• PV production metering for non-Victron solar inverters connected to a GX device
• Generator output monitoring in off-grid and hybrid systems
• Single-phase energy monitoring via the VRM portal

Installation notes

The ET112 should be installed by a qualified electrician, wired in-line with the AC supply at the measurement point. A USB to RS-485 interface is required for communication with the GX device and is not included.
