APsystems ECU-C Energy Communication Unit with Integrated Meter

The APsystems ECU-C is an energy communication unit and information gateway that collects PV production data from microinverters, monitors grid import/export, and tracks energy consumption via integrated meters. It delivers real-time performance data at module level through the APsystems Energy Monitoring and Analysis (EMA) web and mobile platform.

The ECU-C features stable encrypted ZigBee 2.4 GHz wireless communication with up to 100 microinverters, built-in Wi-Fi and Ethernet connectivity, and an internal relay for controlling external devices. Advanced functions include power export limiting, zero export capability, and high-frequency metering. Suitable for single-phase and three-phase systems.

Compact and fanless with natural convection cooling, the ECU-C measures 210 × 120 × 41 mm and weighs 500 g. AC supply is 110–277 VAC (50–60 Hz), with optional DC supply. Supplied without current transformers (CTs).
