Description

Product Description

• Three-phase smart meter that measures active energy and other electrical parameters in residential and commercial solar installations.

• Provides bidirectional monitoring of power flow, enabling tracking of both grid import and export values for system optimisation and export limitation.

• Designed for compact DIN rail installation inside distribution boards or switchgear.

• Employs RS485 communication (Modbus RTU) for integration with Sungrow inverters, smart communication boxes, and monitoring platforms.

• Accuracy suitable for energy billing-level monitoring and precise system performance analysis.

• Suitable for smart energy management, export control, self-consumption tracking, and grid compliance in three-phase solar systems.
