ADL200N-CT Single Phase AC Energy Meter (External CT)
Description
The ADL series is an intelligent DIN-rail mounted meter designed for new energy systems, including photovoltaic grid-connected, micro-inverter, energy storage, and AC coupling setups. It features high-precision measurement, compact design, fast response, and easy installation. The meter samples, monitors, and communicates power parameters with inverters or EMS, prevents reverse power flow, regulates power generation, manages battery charging and discharging, supports bidirectional metering, and enables efficient household distributed photovoltaic energy management.
