Solis SDM630 MCT Three-Phase Smart Meter with CTs
The Solis SDM630 MCT Three-Phase Smart Meter is a high-accuracy energy meter designed for monitoring and managing three-phase electrical systems in residential, commercial, and industrial solar installations.
Designed for use with external current transformers (CTs), the SDM630 MCT provides comprehensive real-time measurement of electrical parameters including voltage, current, power, power factor, frequency, and imported/exported energy. It communicates with compatible Solis inverters via RS485 Modbus RTU, enabling advanced energy management, export limitation, and system monitoring.
