Aurora Inverter error codes

Originally designed by Power One and now fully owned by ABB, the world’s second largest solar inverter manufacturer, Aurora/ABB Inverters are incredibly popular in Australia due to their ability to cope with the tough Australian climate while maintaining low life cycle cost for your solar system. ABB power inverters are designed to help customers generate and use solar energy efficiently.

Not everything is perfect all the time so here is a list of common Aurora Inverter Error Codes with the potential cause and solutions to fix them.

Ground fault Measure the insulation resistance using a megohmmeter positioned in the photovoltaic field (positive terminal short-circuited at the negative pole) compared to ground. The measurement is strongly influenced by the environmental conditions, so must be taken under the same conditions in which the error occurred. – If the value measured is lower than 1 megaohm, a check must be carried out by a technician/installer on the photovoltaic generator to identify and eliminate the problem. – If the value measured is higher than 1 megaohm and the error signal persists, contact customer assistance.
W001 Sun Low This error indicates a low DC, which is normal on cloudy days, in the early morning and in the late afternoon. Outside of these situations, it might suggest a panel issue. You will need to book a 68 point Solar health check so our electricians can test your panels.
E001 Input OC Best to book a 68-point Solar Health Check your Panels. If they are not faulty, the inverter needs replacing.
W002 Input UV Please book a health check so our electricians can test your panels. If they are not faulty, the inverter will need replacing.
E002 INPUT OV Please book a health check so our electricians can test your panels. If they are not faulty, the inverter will need replacing.
E003 Int.Error The inverter will need replacing.
E004 BULK OV Please book a health check so our electricians can test your panels. If they are not faulty, the inverter will need replacing.
E005 Int.Error As this is a communication error, a reset of the system might fix it. If it doesn’t, the inverter will need replacing.
E006 OUT OC The inverter will need replacing.
E007 Int.Error The inverter will need replacing.
E008 Int.Error The inverter will need replacing.
E009 Int.Error The inverter will need replacing.
W003 Grid Fail Check that the solar supply main switch is on. If it is, the inverter will need replacing.
E010 Int.Error The inverter will need replacing.
E011 Int.Error The inverter will need replacing.
E012 dc/dc fail Please book a health check so our electricians can test your panels. If they are not faulty, the inverter will need replacing.
E013 wrong mode Please book a health check so our technicians can check the settings on your inverter. If they are all correct, the inverter will need replacing.
E014 over temp Best to book a 68-point Solar Health Check your Inverter settings If they are not faulty, the inverter may need replacing.
E015 cap Fault The inverter will need replacing.
E016 inv fail Best to book a 68-point Solar Health Check your Inverter settings If they are not faulty, the inverter needs replacing.
E017 Int.Error
E018 ground D Best to book a 68-point Solar Health Check Your panels may be the issue or the Installation method. If they are not faulty, the inverter needs replacing.

E020 Int.Error The inverter will need replacing.
E021 Int.Error The inverter will need replacing.
E022 Int.Error
E023 Int.Error The inverter will need replacing.
W004 grid OV This fault indicates a grid issue and should be intermittent. If it is constant, the inverter may need replacing.
W005 Grid UV This fault indicates a grid issue and should be intermittent. If it is constant, the inverter may need replacing.
W006 GRID OF This fault indicates a grid issue and should be intermittent. If it is constant, the inverter may need replacing.
