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?

I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Hugh Speirs · Apr 2026 Trustpilot

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

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.

Common Failures

Why Aurora inverters fail

🔴 E001 / E017 — Grid fault trips

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.

⚠️ Display failure / no interface

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.

📉 Complete power board failure

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.

Replacement Options

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.

FAQ

Frequently asked questions

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.
