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 five-minute safety delay period.
3. 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:
The status LED for on each microinverter will blink green
three (3) times to indicate normal operation once DC power is applied.
It is important to understand that this “start up” sequence occurs once
the first module is connected to the microinvert and is successfully
generating DC power. The “start up” sequence does NOT reoccur as
additional modules are connected to the same microinverter.
