My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.
Aurora Power-One Inverter Failed — Assessment & Replacement UK
E001/E017 grid faults, display failure, or complete power loss — we assess Aurora faults and advise whether repair or replacement is the best option.
Book replacement assessmentSee all servicesI reached on behalf of a friend, who had lost control of their battery following a storm. A couple giv energy “dealers” had attempted and said different fixes. None worked. Solar tech support solved it remotely on the first attempt almost instantly. Genuinely a 10/10 service.
Prompt and useful support regarding my Sunsynk system lack of performance. Ronald simplified the technical issues to make them understandable. Many thanks, looking forward to follow up.
My Givenergy battery stopped working nearly a month ago. After unsuccessfully reaching out to my installer, who looks like he's also busted, I found Solar Tech Support on a Google search. They fixed my issue in a couple of hours. Any frustrated Givenergy customers, I highly recommend these guys.
Ron was really helpful. He remotely adjusted my battery settings on the same day I contacted him, and at a reasonable price. Great service.
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
Power One / Aurora inverter warranty in the UK: the position
The short answer: there is no manufacturer warranty left to claim against. Power-One was bought by ABB in 2013. ABB then left the solar inverter market in 2020, selling the division to FIMER, and FIMER went into bankruptcy in 2022. Warranty claims cannot be submitted, units can no longer be registered, firmware updates have stopped and the manufacturer monitoring platform has been discontinued.
A dead warranty does not mean a dead inverter, though. Third-party specialists in the UK still handle Aurora faults using existing stock, and the E001 and E017 alarms are often high grid voltage rather than a fault in the inverter at all. Tell us what yours is doing and we will say whether repair is realistic or replacement makes more sense. The remote diagnostic is free, so finding out costs you nothing.
About Aurora Power-One — why your inverter may no longer be repairable
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.
