5.APsystems microinverter system operating instructions
To operate the APsystems microinverter PV system:
1. Turn ON the AC circuit breaker on each microinverter AC branch circuit.
2. Turn ON the main utility-grid AC circuit breaker. Your system will start producing power
after a few minutes waiting time.
3. The LED should blink green every 2 seconds. This means that the operation is normal.
4. Connect the ECU communication gateway (optional) and follow the instructions in the
manual. Once the ECU is plugged in and set up, it recognizes the microinverters, then the
LED flashes green every 10 seconds.
5. The APsystems Microinverters will start to send performance data to the ECU. The time
required for all the microinverters in the system to report to the ECU will vary with the
number of microinverters in the system. You can verify proper operation of the APsystems
Microinverters via the ECU. See the ECU Installation and Operation Manual for more
information.
