Product Description

Eastron SDM230-Modbus PV Solar System Electricity Smart Meter

The Eastron SDM230-Modbus is a multifunction single-phase smart energy meter designed for residential electricity monitoring, solar PV systems, and EV charging applications. It measures active and reactive energy, voltage, current, power, power factor, and frequency, providing useful data for energy management and system monitoring.

Featuring RS485 Modbus communication, two pulse outputs, and bidirectional energy measurement, the SDM230-Modbus supports remote data collection and monitoring of imported and exported electricity. Its direct-connected design and compact 36 mm DIN-rail mounting make it a practical solution for residential and commercial energy monitoring.

Product Features

  • Bidirectional Energy Measurement: Monitors imported and exported electricity for solar PV applications.

  • Multifunction Measurement: Measures voltage, current, active and reactive power, energy, power factor, and frequency.

  • RS485 Modbus Communication: Enables remote monitoring and integration with compatible energy management systems.

  • Dual Pulse Outputs: Supports external energy data collection.

  • Direct Connection: Supports up to 65A without external current transformers on the linked model.
