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 and 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 over
power line 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.
NOTE:
Once AC power is applied, about 0.1A current and 25VA(W)
power for each microinverter may be measured with a meter. This
Current and Power are Reactive. The inverters ARE NOT operating.
After an over 60s waiting time, the inverters will start operation.
