APsystems Microinverter System Operating Instructions
To operate the APsystems microinverter PV system:
1.
Turn ON the AC circuit breaker on each microinverter branch
circuit.
2.
Turn ON the main utility grid AC circuit breaker. Your system
will start producing power after a five-minute wait 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.
4.
Plug in the ECU and follow the instructions according to the
manual for the ECU.
5.
After the ECU has been plugged in and acknowledges the
microinverters, they will start to blink green every 10 seconds.
6.
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. Once communications have been established
between the ECU and the inverters, the microinverters will
start to send performance data over power line to the ECU. You
can verify proper operation of the APsystems microinverters via
the ECU. See the ECU Installation and Operation Manual for
more information.
