APsystems Energy Control Unit (ECU)



The APsystems (formerly APS) ECU-3 Energy Control Unit is the internet gateway device that communicates with each APsystems microinverter and downloads system data to the internet. The installation of an ECU is not essential for an APsystems installation, however you do need to install one if you want access to real time and historical system data via the internet. The standard ECU provides access to aggregated system level data.  Access to module level data is available at additional cost.  Please contact us for further details.
