The APsystems ECU (Energy Communication Unit - C) is the information gateway for the micro-inverters and the solar panels. The module collects the performance data of each individual micro-inverter and sends this information to a database, connected only with a single data and power cable. Via the APsystems EMA application, the ECU gives you accurate analyses of each micro-inverter and each solar panel from your mobile phone, tablet or computer. The user-friendly interface gives you access to your solar system in seconds. Standard equipped with Wifi and Zigbee.
