Home / Products / Energy Meter / AC Energy Meter / AC Dual Circuits WiFi Communication Energy Meter for Balcony Solar PV

ADL series DIN rail-mounted multifunction energy meter with external CTs is a smart energy meter designed specifically for renewable energy systems such as Multi-Inverter Hybrid System (Photovoltaic + Energy Storage Inverter), micro-inverter systems, energy storage systems, and AC-coupling systems.

The product features high accuracy, small size, fast response, and easy installation. It is capable of sampling, measuring, and monitoring electrical parameters.

The inverter or energy management system (EMS) can communicate with it to achieve anti-reverse flow, adjust power generation, and manage battery charging and discharging based on real-time power and accumulated energy. It supports bidirectional metering and enables household distributed photovoltaic energy management.
