The Power One Aurora was made for the UK market as mid range DC Inverter, we have replaced many of this with various errors between 8-12 years old.
The E031 error is a common fault with Aurora/ABB inverters, unfortunately this is not repairable and a new inverter is needed.
Mr Solar has over 15 years in Solar PV and battery systems, we have the most up-to-date Testing and Inspection equipment for PV Panels and Inverter systems. You can now upgrade your Solar Panels with battery storage without losing your Feed in Tariff.
