Aurora Power-One Inverter Failed — Assessment & Replacement UK
Aurora Power-One inverters were quality Italian-made units installed across the UK from 2008 to 2015. Power-One was acquired by ABB in 2013. ABB sold the solar inverter division to Italian manufacturer FIMER in 2020, and FIMER subsequently went into bankruptcy in 2022. Aurora PVI units are now effectively unsupported — no firmware updates, no active manufacturer warranty, and parts availability is severely limited. When an Aurora inverter fails, replacement is usually the most cost-effective route.
Has your Aurora inverter failed?
E001/E017 grid faults, display failure, or complete power loss — we assess Aurora faults and advise whether repair or replacement is the best option.

Aurora Power-One produced the widely-installed PVI series (single-phase) and TRIO series (three-phase) string inverters. They were considered among the highest-quality inverters of their era — many are still generating after 10–15 years. ABB acquired Power-One in 2013 and continued the Aurora product line before selling the entire solar inverter division to Italian manufacturer FIMER in 2020. FIMER subsequently went into bankruptcy in 2022. Aurora inverters can no longer be registered for warranty, and there is no active manufacturer service division. Some third-party service companies hold limited spare parts — feasibility depends on the specific model and fault.
Unlike fully defunct brands, Aurora PVI inverters sometimes remain repairable if the specific fault is a known issue. E001 and E017 faults — the most common Aurora alarms — are often grid-voltage-related and not a defect in the inverter itself. Display module failures can occasionally be addressed. However, power board failures and capacitor issues are harder to resolve without reliable parts supply. A proper fault diagnosis from a specialist is essential before deciding whether repair or replacement is the right path forward.
Why Aurora inverters fail
The most common Aurora alarm. Aurora inverters trip on grid voltage events and log E001 (grid voltage) or E017 (grid frequency). If trips are frequent, check grid voltage at the consumer unit. High local voltage (above 253V) is the most common cause.
The Aurora display module is a separate component that fails independently from the power conversion stage. The inverter may continue generating with a dead display. Replacement displays are difficult to source but occasionally available from specialist parts suppliers.
Total non-generation with no faults displayed. Usually an IGBT or capacitor failure. Repair is possible in some cases where parts can be sourced — assessed on a model-by-model basis.
What should I replace an Aurora Power-One inverter with?
Aurora PVI inverters have wide DC voltage input ranges, making them compatible with most modern string and hybrid inverters. If replacement is the right path, you can maintain your existing panels and DC cabling. A hybrid upgrade at replacement time is often more cost-effective than retrofitting battery storage later.
Upgrade to a hybrid inverter with battery storage — most popular choice for Feed-in Tariff-era system upgrades.

Sometimes — unlike fully defunct brands, Aurora PVI inverters were high-quality units and some specialist companies hold spare capacitors and replacement boards for certain models. Whether repair is viable depends on the specific fault and model. E001/E017 grid faults are often caused by high local grid voltage (not an inverter fault at all) and require no parts — only settings adjustment. Complete power board failure is harder: parts availability varies by model. We assess repairability before recommending replacement.
ABB's withdrawal from the solar inverter market in 2020 means there is no manufacturer support for Aurora inverters. Warranty claims cannot be submitted to ABB, firmware updates are no longer available, and ABB's monitoring platform has been discontinued. The inverters themselves continue to operate but without any manufacturer backup. Third-party service companies handle Aurora faults in the UK using existing stock and reverse-engineering knowledge.
Any modern string or hybrid inverter with compatible DC input specifications can replace an Aurora PVI unit. Aurora inverters often have wide voltage ranges (125–750V Vdc) which is compatible with most modern string inverters. If you want to add battery storage, a hybrid inverter (GivEnergy, Growatt, Solis) is the most cost-effective upgrade at replacement time rather than retrofitting later.
Yes. STS can replace legacy Aurora inverters with modern hybrid inverters, allowing you to maintain your existing panels while upgrading to current-generation power conversion and adding battery storage capability. Replacement typically costs from £795, depending on your system size and chosen replacement model. We handle the complete replacement including decommissioning the old inverter, installing the new unit, and integration with modern monitoring platforms.
