WARNING: Always disconnect AC power before disconnecting the PV panel wires from the
inverter. The AC connector of the first inverter in a branch circuit is suitable as a
disconnecting means once the AC branch circuit breaker in the load center has been opened.
2. Troubleshooting an Inoperable Inverter (For Experienced Installers)
To troubleshoot an inoperable inverter, follow the steps in the order shown:
1. Check the connection to the utility grid. Verify the utility voltage and frequency is within
allowable ranges shown in the Technical Data section on page of this document. Verify
utility power is present at the inverter in question by removing AC, then DC power.
Never
disconnect the DC wires while the inverter is producing power. Re-connect the DC panel
connectors and watch for six short LED flashes.
2. Check the AC branch circuit interconnection harness between all the inverters. Verify each
inverter is energized by the utility grid as described in the previous step.
3. Make sure that any AC disconnects are functioning properly and are closed.
4. Verify the PV panel DC voltage is within the allowable range shown in the Technical Data
page of this document.
5. Check the DC connections between the inverter and the PV panel.
6. If the problem persists, please call customer support at Westinghouse Solar.
3. Disconnecting the Inverter from the PV Panel
To ensure the inverter is not disconnected from the PV panels 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 panel with an opaque cover.
4. Using a DC current probe, verify there is no current flowing in the DC wires between the
Westinghouse Solar panel and the inverter.
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 Westinghouse Solar panel DC wire connectors from the inverter.
7. Remove the inverter from the Westinghouse Solar AC frame.
