Troubleshooting

Replacing a Non-operational MicroGT 500 Inverter

1. Disconnect the MicroGT inverter from the PV module in the
order below:
a) Disconnect the AC by turning off the branch circuit breaker.
b) Disconnect the AC connector(s) from the adjacent inverter(s)
in the branch circuit.
c) Disconnect the PV module DC MC4 wire connectors from the
microinverter to be replaced.
d) Remove the MicroGT inverter from the PV array.
2. Install a replacement MicroGT inverter to the rack. Remember to
observe the fl ashing LED light as soon as the new microinverter
is connected to the DC PV module cables.
3. Connect the AC cable of the replacement MicroGT inverter and
the neighboring microinverter to complete the branch circuit
connections.
4. Close the branch circuit breaker, and then verify operation of
the replacement microinverter.
WARNING: Be sure to verify that the voltage and current
specifi cations of your PV module match those of the
microinverter.
WARNING: You must match the DC operating voltage
range of the PV module with the allowable input voltage
range of the MicroGT inverter.
WARNING: The maximum open circuit voltage of the PV
module must not exceed the specifi ed maximum input
voltage of the MicroGT inverter.
