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 two-minute waiting time.
3. The units should start blinking green every 2 seconds five minutes after turning on the AC
circuit breaker. This means they are producing power normally, but have not yet connected
to the ECU. After the ECU has been plugged in, setup acknowledges the Microinverters,
they will start to blink green every 10 seconds.
4. Plug in the ECU and follow the instructions according to the manual for the ECU.
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.
