Making a manufacturer warranty claim
without your installer
- Manufacturer warranties survive installer closure
- You can claim directly — no installer required
- Diagnostic report is essential for most claims
Our Warranty Claim Support service provides a written diagnostic report identifying the fault and its nature — the key document manufacturers require before processing a claim. We also handle direct correspondence with manufacturer warranty teams on your behalf.
Warranty Claim SupportBook your free diagnosticI 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 Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
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
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.
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.
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!

The three separate warranties on every solar installation
Understanding which warranty applies to your situation is the first step. They are issued by different parties and behave completely differently when an installer closes.
Covers component failure on the inverter (5–12 years), battery (5–10 years), and panels (10–25 years). Issued by the manufacturer — not the installer. Completely unaffected by installer closure. Claimed directly with the manufacturer using the serial number.
Covers installation errors — miswired CT clamps, incorrect export limit configuration, poor cable management, mounting issues. Typically 1–5 years. Issued by the installer. When the company closes, there is no one left to honour it. Cannot be transferred.
If the installer was registered with HIES or RECC, there may be consumer protection covering remedial work up to £2,500 — a partial replacement for the lost workmanship warranty. Check both registers at hiesscheme.org.uk and recc.org.uk.
Key point: Most homeowners assume all their warranties are gone when an installer closes. The manufacturer warranties — which cover the most expensive components — survive completely. The only warranty that disappears is the installer's workmanship warranty, which only covered how the system was fitted.
Manufacturer warranty periods — what's still covered
The manufacturer warranty period starts from the installation date — not the purchase date. Check the MCS certificate for the system installation date.
GivEnergy: 10 years · Sunsynk: 10 years · SolarEdge: 12 years · Growatt: 5 years standard (10-year extension available) · Solis: 5–10 years depending on model · Enphase microinverters: 25 years. Covers complete component failure and manufacturing defects. Does not cover installation errors such as DC cable undersizing or incorrect firmware configuration.
GivEnergy battery: 10 years · Sunsynk battery: 10 years · Growatt battery: 5–10 years depending on model · Pylontech (used by many installers): 10 years · SolarEdge Energy Bank: 10 years. Batteries also carry a performance guarantee — the battery will retain a minimum capacity percentage (typically 60–70%) at end of warranty period.
Panels carry two separate warranties: a product warranty (10–15 years, covers manufacturing defects and physical failures) and a performance warranty (typically 25 years, guarantees a minimum power output at end of term, usually 80%). Panel brands vary — check the label on the rear of a panel or the MCS certificate for the brand, and then the manufacturer's website for specific warranty terms.
Any fault that arose from how the system was installed — wiring errors, incorrect CT clamp orientation, undersized DC cables, improper earthing, export limit misconfiguration — is a workmanship issue. The installer warranty that covered these is now void. Correction of workmanship faults requires an independent engineer and may be covered by HIES or RECC consumer protection if the installer was registered.
Step-by-step: making a direct manufacturer warranty claim
Follow these steps in order. The diagnostic report (step 4) is the most important and the most commonly missing piece in homeowner claims.
Is the fault with the inverter, the battery, or the panels? Each has a separate manufacturer and a separate warranty claim process. The inverter and battery manufacturers are shown on the labels on those units. Panel manufacturer is on the rear label of any panel (accessible via loft if the roof space allows) or on the MCS certificate.
Every warranty claim requires the serial number of the specific component. Inverter serial number is on the label on the side or rear of the unit. Battery serial number is on the label on the battery unit itself. Panel serial numbers are on the back of each panel individually. Without the serial number, the manufacturer cannot locate the product record or confirm warranty validity.
Warranties run from the installation date. The MCS certificate (searchable at mcscertified.com using your postcode) gives the installation date. If the MCS was never registered, look for the commissioning report or any dated documentation from the installer. If you're within the warranty period, proceed. If you're close to the boundary, act immediately — most manufacturers will process a claim submitted within warranty even if repair takes slightly longer.
This is the most critical step — and the one most homeowners skip, then hit a wall. Manufacturers need third-party evidence that the fault is a genuine component failure rather than a configuration error, installation problem, or user-caused issue. A written report from an independent engineer identifying the fault code, its likely cause, and its nature (component vs workmanship) is what unlocks most stuck warranty claims.
Without a diagnostic report, most manufacturers will ask for one before processing the claim — adding weeks to the timeline. Get the report first.
Contact the manufacturer's UK warranty or technical support team by email (creates a paper trail). Include: serial number, fault description, diagnostic report, installation date, your address, and a statement that the original installer has ceased trading with the Companies House reference if available. Request written confirmation of claim receipt and a reference number. Follow up if you don't hear within 5 working days.
Warranty claim contacts for major UK brands
Contact details and notes for each manufacturer's warranty process. Always use email to create a record of your claim.
Warranty: 10 years inverter, 10 years battery. Contact: support@givenergy.co.uk or via givenergy.cloud support portal. GivEnergy UK support is generally responsive and has a documented process for installer-gone-bust warranty scenarios. Provide serial number, fault description, and diagnostic report.
Warranty: 10 years inverter, 10 years battery. Contact: support@sunsynk.co.uk. Sunsynk UK handles warranty claims centrally. Include serial number, fault description, and installation date in initial contact. They will typically ask for a diagnostic report as a second step if not provided upfront.
Warranty: 12 years inverter, 10 years battery. Contact: support.uk@solaredge.com. SolarEdge has a formal warranty process — the most structured of any major brand. They will request fault data from the monitoring portal as well as a diagnostic report. Include serial number and the system ID if available from the monitoring platform.
Warranty: 5 years standard, 10-year extension available at purchase. Contact: service@growatt.com (UK distributor). Growatt UK handles warranty via their service team. Provide the fault code from the display, serial number, installation date, and diagnostic report. Growatt often needs the device to be accessible remotely via ShineServer for preliminary fault assessment.
Warranty: 5–10 years depending on model. Contact: info@solisinverters.com. Solis UK support handles warranty claims via their service team. Typical process requires fault description, serial number, and engineer report. Solis also has a UK partner network that can conduct site assessments as part of the warranty process.
Warranty: 25 years on microinverters. Contact: support@enphaseenergy.com. Enphase microinverter warranties are among the strongest in the industry. Individual faulty microinverters are replaceable under warranty — they don't require all-or-nothing claims. Contact UK support with the Envoy serial number and details of which microinverters are showing faults on the Enlighten platform.
When the manufacturer insists on an installer claim
Some manufacturers (particularly for complex faults) will initially push back on homeowner warranty claims, stating that claims must be submitted by the installing engineer. When the installer has ceased trading, this is a fixable problem — not a dead end.
Front-line support agents often follow a script that routes warranty claims through installers. Senior warranty and technical teams have the authority to process direct homeowner claims. Ask explicitly to be escalated and reference the Companies House record showing installer closure.
A printed or downloaded Companies House record showing the installer's company as dissolved or in administration is the clearest evidence that normal warranty processing routes are unavailable. Search gov.uk/get-information-about-a-company for the installer's company name and download the record.
If the installer was HIES or RECC registered, you may be able to use the consumer protection complaint process as a route to getting the work covered without relying on the manufacturer warranty at all. This is worth pursuing in parallel, especially for workmanship-related faults where manufacturer warranty won't apply regardless.
A professional warranty claim support service provides a written diagnostic report and handles direct manufacturer correspondence on your behalf. Claims submitted through a service with an existing manufacturer relationship are processed faster and are less likely to stall at front-line support deflection.
Consumer protection when manufacturer routes fail
If the fault is a workmanship issue (not covered by manufacturer warranty) or manufacturer warranty claims are refused, these routes may still provide a remedy.
If the installer was HIES-registered at time of installation, you may have up to £2,500 cover for remedial work, deposit protection, and access to an alternative dispute resolution process. Search hiesscheme.org.uk for the installer's company name.
Renewable Energy Consumer Code. Similar protection to HIES — covers remedial work and dispute resolution if the installer was a RECC member at the time. Search recc.org.uk independently — some installers were registered with one scheme but not the other.
If you paid by credit card and the total contract value exceeded £100, Section 75 of the Consumer Credit Act makes the card issuer jointly liable. For debit cards, Chargeback may apply. Contact your bank — there are time limits, so act early.
