Solis Meter 1ph Eastron with external CT - SDM120CT

The Solis 1 Phase Eastron SDM120CT Smart Meter is a high-accuracy energy monitoring device designed specifically for use with compatible Solis single-phase hybrid and grid-tied inverters. Supplied with an external Current Transformer (CT), this meter provides precise real-time measurement of electricity import, export and household consumption, allowing your inverter to intelligently manage power flow throughout your property.

Ideal for residential solar PV installations, the SDM120CT enables advanced energy management features including export power limitation, self-consumption optimisation and accurate monitoring of grid energy usage. By measuring the power flowing at your property's grid connection, the Solis inverter can prioritise solar generation, battery charging and household loads to maximise energy independence.

This meter communicates directly with compatible Solis inverters via RS485 Modbus communication, providing fast and reliable data transfer. It is commonly required when configuring export limitation settings or when installing battery storage systems where accurate whole-home energy monitoring is essential.
