The AUO Data Logger is a gateway device that uses Power Line Communications (PLC) to collect status and performance
data from AC Unison modules. Using broadband Internet, the Data Logger then forwards the collected data to the Solar
Monitoring System at five minute intervals. When necessary, the Data Logger automatically downloads and installs
enhancements, which can include defect fixes, to the software on the Data Logger or, on rare occasions, to the firmware on
the micro-inverter. No manual intervention is required during the update process. The following diagrams illustrate the exterior
and interior features of the Data Logger.
