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 servicesWe reached out to Solar Technical Support after our solar energy system stopped working. As GivEnergy 'solar orphans,' we have been extremely pleased with the service from STS - our system was back up and working within a day of us contacting them. We found other solar engineers reluctant or unable to help us, so it has been great to find this organisation. We would definitely use them again and would recommend them to anyone, especially GivEnergy orphans!
When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.
My GivEnergy solar and battery system is failing intermittently, GivEnergy is in administration and so is my installer, so it was a relief to get Ron’s expert advice.
Ron has come to our rescue once again! After sorting out our GivEnergy battery issue, he was on hand to help us find a solution to data logging issues caused during install of an additional inverter. He's helpful, patient and extremely knowledgeable. Utterly brilliant service. Thank you again!
We were having problems with our inverter, couldn’t get an early response from our installer a stressed conversation between our installer and solar tech support led to a text to us to authorise connection to your company . Ron was a very helpful and knowledgeable man who tried with a bit of difficulty as we are pensioners and very knowledgeable. Spent time on phone without making us feel small.we would recommend this company if you have any problems. Thanks Ron 5 star
Ron is one of those rare finds - an engineer's engineer. He insightfully and accurately diagnosed the problems with our GivEnergy system, very quickly, which helped get us back on track. We will be using him again!
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.
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.
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.
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.
