Troubleshooting an inoperable AUM micro inverter
To troubleshoot an inoperable AU-1P20002G, follow the steps in the order shown:
1. Check the connection to the utility grid. Verify that the utility voltage and
frequency are within allowable ranges shown in the label of AU-1P20002G.
2. Verify utility power is present at the inverter in question by removing AC, then DC
power. Never disconnect the DC wires while the AU-1P20002G is producing
power. Re-connect the DC module connectors, and then watch for the LED blinks.
3. Check the AC branch circuit interconnection harness between all the
AU-1P20002G. Verify that each inverter is energized by the utility grid as described
in the previous step.
4. Make sure that any AC disconnects are functioning properly and are closed.
5. Verify the PV module DC voltage is within the allowable range shown in the label
of AU-1P20002G.
6. Check the DC connections between the AU-1P20002G and the PV module.
7. PLC signal quality may be checked through the interface on the AUG-256 gateway.
If the PLC signal is weak, it might be due to the distance between the micro
inverters and the gateway. It may also be caused by the interference from other
electronic devices. In most cases, signal quality may be significantly improved by
moving the AUG-256 to closer to the micro inverter arrays, and/or farther away
from other interferers. In some cases, a signal filter (LCF) may be installed to
reduce the interference to PLC communication. If there are two or more
separate AUM systems close by, it is highly recommended to install LCF for each
micro inverter system to block interference from adjacent other systems.
7. If the problem persists, please call customer support at Austa.
WARNING:
DO NOT ATTEMPT TO REPAIR THE AUM-2000; IT CONTAINS NO
USER-SERVICEABLE PARTS. IF TROUBLESHOOTING METHODS FAIL, PLEASE RETURN THE
AUM-2000 TO YOUR DISTRIBUTOR FOR MAINTENANCE.

Disconnecting a AU-1P20002G from the PV Module
To ensure the AU-1P20002G is not disconnected from the PV modules under load,
adhere to the following disconnection steps in the order shown:
1. Disconnect the AC by opening the branch circuit breaker.
2. Disconnect the first AC connector in the branch circuit.
3. Cover the module with an opaque cover.
4. Using a DC current probe, verify there is no current flowing in the DC wires between
the PV module and the AU-1P20002G.
5. Care should be taken when measuring DC currents, most clamp-on meters must be
zeroed first and tend to drift with time.
6. Disconnect the PV module DC wire connectors from the AU-1P20002G.
7. Remove the AU-1P20002G from the PV array racking.
Installing a replacement AU-1P20002G
1. Attach the replacement AU-1P20002G to the PV module racking using hardware
recommended by your module racking vendor
2. Connect the AC cable of the replacement AU-1P20002G and the neighboring
AU-1P20002G to complete the branch circuit connections.
3. Complete the connection map and connect the PV Modules.
1) Complete the connection map
2) Each AU-1P20002G has a removable serial number located on the mounting plate.
Enter this serial number into a AUG-256, and correspond it to a number in the
connection map.
3) Connect the PV Modules
4) Completely install all AU-1P20002G and all system inter-wiring connections prior
to installing the PV modules.
a) Mount the PV modules above their corresponding AU-1P20002G. Each
AU-1P20002G comes with two oppositely sexed DC connectors.
b) First connect the positive DC wire from the PV module to the negatively
marked DC connector (male pin) of the AU-1P20002G. Then connect the
negative DC wire from the PV module to the positively marked DC connector
(female socket) of the AU-1P20002G. Repeat for all remaining PV modules
using one AU-1P20002G for each module.
4. Replace the old PLC_ID in the AUG-256 gateway with the new PLC_ID of
the replacement micro inverter.
