Aurora Solar Inverter Error Codes Explained

ERROR CODE CAUSE SOLUTION
No Code / RED LED 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.

On 4/11/2026, Pomepe and apprentice Aden arrived to instal a new laundry unit which had been found faulty on an earlier free plumbing inspection. On arrival and inspection of the Job, Pomepe explained that the job would require tile cutting as the old unit was installed as the house was being built. He assured us that the finished job would be satisfactory. It Is. They went about the job quietly and quickly, and on completion removed and disposed of the old unit, fittings and packaging. Before leaving Pomepe advised us to wait some time before using the unit to allow sealants to cure. This service was typical of the service we have come to expect of Fallon Solutions over many years. We would also like to commend JASMINE, the lady who showed such patience trying to educate a 90 year old how to submit this review on a mobile phone
