Should the Inverter appear to be malfunctioning we suggest the following to eliminate any external problems.
1. Turn the Inverter "OFF" by disconnecting the DC Solar input and then disconnecting the AC grid.
2. Reconnect the DC Solar Input. All lights on the inverter should come ON for 1 second on power up and
then go OFF. The centre or 3
voltage needs to be >100V for the light to turn ON. If the light does not illuminate check Solar Input for
correct operation.
3. Next reconnect the AC grid. After 10 seconds the centre or 3
inverter reconnection to the AC grid. The light will flash for approx 90 seconds while the PV edge checks
the mains voltage and frequency are stable. Should the light not begin flashing check if the AC grid is
present. Also check internal fuse at top of circuit board above AC terminal block. (see Figure 2)

4. After the 3
light stops flashing the inverter will begin feeding power into the AC grid.
Helpful Hints

• Remember that it has automatic reconnection to the AC grid.
• Make sure leads and terminals are not corroded, loose or faulty in any way.
• Make sure circuit breakers or switches are reset properly. If unsure switch OFF and ON again.
