Solis Meter 3-Phase Eastron V2 with CTs (SDM630MCT V2)

The Solis Eastron SDM630MCT V2 is a three-phase, CT-operated MID energy meter designed for accurate monitoring of commercial and industrial solar installations. Suitable for Solis three-phase hybrid and grid-tied inverters above 12kW (above 120A), this meter provides reliable bi-directional energy measurement for import and export applications.

The meter operates using external current transformers and supports both 1A and 5A CT inputs. Supplied with 3 × 300A CTs, it offers a wide operating range and is ideal for higher-capacity three-phase systems. The unit requires an auxiliary power supply (AC or DC) to operate and can alternatively be powered directly from the monitored supply where appropriate.

Comprehensive Energy & Power Monitoring

The SDM630MCT V2 measures and displays a full range of electrical parameters across single-phase and three-phase systems, including 1p2w, 3p3w, and 3p4w supply configurations. Energy is measured in both active and reactive formats, enabling precise system performance analysis and compliance monitoring.

Measured parameters include:

• Line voltage and total harmonic distortion (THD%) for all phases

• Line frequency

• Phase currents, current demand and current THD%

• Active, reactive and apparent power (kW, kVAr, kVA)

• Power factor and maximum demand values

• Active energy imported and exported (kWh)

• Reactive energy imported and exported (kVArh)

Maximum demand can be measured over configurable periods of up to 60 minutes, allowing detailed load profiling and system optimisation.

Communication, Outputs & Integration

Built-in communication interfaces provide seamless integration with Solis inverters, energy management systems, and BMS platforms. The meter includes RS485 Modbus RTU communication for remote monitoring and data acquisition, as well as dual pulse outputs for real-time energy indication.

Key communication features:

• RS485 Modbus RTU output for remote monitoring

• Two configurable pulse outputs

• Password-protected configuration and setup screens

CT ratios are fully configurable, supporting a wide range of primary currents while maintaining high accuracy across installations.
