Fronius

102 – High Voltage
Problem: Western Power’s grid voltage is too high and the inverter is shutting down to protect itself.

Solution: Monitor the inverter over 2-3 days to see if the issue continues as this can just be an intermittent fault due to grid works or disturbances.
NOTE: If the fault does not go away we will need to contact western power and lodge a submission for over-voltage.

567 – High Voltage…. Inverter ramping down (smoothing)
Problem: Western Power’s grid voltage is rising and the inverter is ramping down.

Solution: It is an Australian standard that the inverter has this function. One way to reverse the voltage increase is by increasing the load in the house.

996 – Communication error
Problem: The inverter is no longer connected to the portal/internet/wifi.

Solution: Have you changed your network provider/wifi password/gone nbn. Click here for the step by step to reconnect

475 – Earth Isolation
Problem: Potential water ingress in isolator or panel/plug. If received very early in the morning it can also be triggered by low light.

Solution: Please lodge a service ticket through the form at the bottom of this page or call us on 9300 9324.

If the green light doesn’t come on and the inverter is still displaying this error code then please lodge a service ticket through the form at the bottom of this page.

306 to 307 – Low PV/DC
Problem: Low DC Power coming from the panels.

Solution: *When did the code display? Did it go away? This code can display in the very early morning and very late evenings when the solar is switching off.

Sungrow

STATUS CODES

2, 3, 14, 15 – Grid Overvoltage
Problem: Western Power’s grid voltage is too high and the inverter is shutting down to protect itself.

4, 5 – Grid Undervoltage
Problem: Western Power’s grid voltage is below the inverter allowable limit.

Solution: Generally, the inverter will be reconnected to the grid after the grid returns to normal. Monitor the inverter over 2-3 days to see if the issue continues as this can just be an intermittent fault due to grid works or disturbances. If the fault occurs repeatedly please create a service ticket using our website chat or using the form at the bottom of this page.

Disconnect/No connection – Communication error
Problem: The inverter is no longer connected to the portal/internet/wifi.

Solution: Have you changed your network provider/wifi password/gone nbn. Click here for the step by step to reconnect
