In case of fault, Austa inverter has multiple protective functions and stops output power. The fault m
essage may be sent to a connected gateway through power line communication.
1. Do not attempt to repair the microinverter; the microinverter contains no user-serviceable parts. If
troubleshooting methods fail, return the microinverter to your dealer for repair.
2. Never disconnect the DC lead connector under load. Make sure there is no current in the DC leads
before disconnecting. Before disconnecting, the module can be covered with thermal insulation.
3. The product is powered by the DC power supply of the PV module. Make sure you disconnect the D
C power supply Make sure you disconnect the DC power supply and reconnect the DC power supply
to observe the LEDs come on for two seconds and the LEDs go off for two seconds after the DC power
supply is turned on.
4. Always disconnect AC power before disconnecting PV module wiring from the microinverter.Micro-
inverter AC Once the AC branch circuit breaker at the load centre has been opened, the AC connector
of the first microinverter in the branch circuit serves as the means of disconnection.
The micro inverter is powered on when sufficient DC voltage from the module is applied. The status
LED will start flashing after sufficient DC power is applied as an indication that the micro inverter is
live.
