Description

Eastron SDM120CTM Smart Meter for Solis is the ideal single-phase energy meter for precisely capturing the current flow in your photovoltaic system. As a current-transformer-operated device (external CT, 1/5A), it measures grid consumption and feed-in bidirectionally and provides your Solis inverter with reliable data for optimized self-consumption – with accuracy class 1 for active energy.

Key benefits for your system

Bidirectional measurement: Captures both grid consumption and feed-in for an accurate energy balance.
Modbus communication: Integrates directly into your Solis system via RS485 Modbus RTU.
Certified accuracy: MID B+D certified with accuracy class 1 for active energy.
Easy installation: Compact design for DIN rail mounting with a width of just 18 mm.

Smart control of your solar power

A precise smart meter is the foundation for high self-consumption of your solar power. The Eastron SDM120CTM captures the energy flow at your grid connection point and transmits these values via RS485 Modbus RTU to your Solis inverter. This allows your system to constantly detect how much photovoltaic energy is being generated and consumed, and adjust its control accordingly. The current-transformer-based design also allows use with higher currents via an external CT. The backlit LCD display shows all relevant parameters directly on-site. This gives you greater transparency over your power consumption and increases your independence from the public grid.
