ET112  – REL300100000 — is a single-phase electricity meter that measures AC consumption or generation with maximum accuracy. Designed for integration into Victron Energy systems, the meter connects to Cerbo GX, Ekrano GX, and Venus GX devices via RS-485. It is used in ESS systems, for monitoring home consumption, solar station generation, or measuring power on a sub-network.

Key benefits of the ET112 energy meter

• Measures energy in single-phase networks up to 100 A per phase
• Operates via RS-485 — stable data transmission
• Ideal for homes, businesses, and solar power stations
• Supports measurement of generation, consumption, and grid export
• Enables the creation of a visual energy flow diagram in the Victron system
• Fully compatible with GX devices (Cerbo GX, Ekrano GX, etc.)
