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!

When to use this service

Complete system failure

Inverter not starting, battery completely unresponsive, or no generation at all on a clear day

EPS backup not activating

Your backup power failed during a grid outage. A critical safety and commissioning issue — do not leave this unchecked

Safety-critical alarms

Isolation fault, arc fault detection, earth leakage — alarms that indicate a potential safety risk, not just a configuration error

Time-critical situations

System needs to be working by a specific date — property sale, lettings inspection, business continuity — and you can't wait for a standard booking slot

Battery charging at maximum rate unexpectedly

A battery importing aggressively from the grid without instruction can indicate a BMS fault or protection event in progress

→

Not an emergency?

For faults that can wait a day or two, a remote diagnostic (£75) is the right starting point

What the callout covers

On-site diagnosis

The callout fee includes a full on-site diagnostic — fault log review, live readings, physical inspection of wiring, connections, and components.

Repair where possible

Minor repairs and adjustments — settings corrections, connection issues, firmware recovery — are carried out during the visit within the callout fee.

Written report

You receive a written report of what was found, what was done on the day, and a clear recommendation for any further work — with costs agreed before proceeding.

If parts are needed: If the repair requires components that aren't on the van — inverter boards, battery modules, specific isolators — we'll confirm the cost and lead time before ordering. The callout fee is not duplicated for follow-up visits to complete a part-based repair.

What qualifies as a solar emergency

Not every solar fault is an emergency. However, certain situations pose safety risks, threaten system integrity, or require urgent response. Below we outline the scenarios that warrant an immediate callout, and why speed matters.

● Burning smell, smoke, or discolouration from inverter or battery enclosure

If you notice a burning smell, see smoke, or observe discolouration, scorch marks, or browning around your inverter, battery storage, or any electrical enclosure: isolate at the consumer unit immediately and call 999 first. This indicates a potential electrical fire or internal component failure. Do not attempt to restart the system. Do not open any enclosures. Your safety is the priority — the system can be repaired later. Once emergency services have attended, contact us for recovery and repair.

● DC arc fault detection or visible arcing

If your inverter has triggered an arc fault shutdown, or you've observed visible sparking or arcing near any DC wiring or connectors, this indicates a fault in the DC circuit that can cause electrical fire. Do not restart the system. Isolate at the consumer unit and call us immediately. Many inverters with arc fault detection are programmed to prevent restart after an arc detection event — this is a safety feature, not a system failure. We diagnose on-site to identify the arc source (usually a damaged connector or corroded wiring) and resolve it safely. Arc faults require immediate professional attention to prevent fire and electrical shock hazards.

● Battery thermal runaway warning or visible swelling

Modern lithium battery systems include BMS (battery management system) protections that trigger shutdown if a cell enters thermal runaway — uncontrolled temperature rise. If your battery shows a thermal warning, or if the battery enclosure is visibly swollen, bulging, or deformed: isolate at the consumer unit immediately and vacate the property if you smell burning or heat. Call 999. Once safe, contact us. A thermal runaway is a serious fire risk and requires professional containment and replacement. Do not attempt any restart.

● Water ingress into inverter or battery enclosure

If water has entered an electrical enclosure — from flooding, condensation, or a roof leak — the risk of electrical shock and short circuits is high. Isolate at the consumer unit immediately. Do not attempt to dry out the unit or restart it. Contact us for urgent on-site assessment. Water damage may require component replacement, but attempting operation risks electrocution and fire. We'll drain, clean, and assess what can be salvaged and what must be replaced.

● Complete system failure during extreme weather or essential periods

If your solar system is your primary or sole source of heating, hot water, or other essential services, and it fails completely during winter, extreme heat, or another critical period, this is a time-critical emergency. A completely non-responsive inverter or battery in these circumstances can affect your health and safety. Contact us immediately and we'll prioritise a same-day response. We carry common replacement parts on the van to minimise downtime. Same-day repair is not guaranteed in all cases, but we treat these situations as top priority.

● Grid fault causing repeated inverter trips with no reset capability

In rare cases, a fault on the grid side (a supply problem or earth fault) can cause an inverter to trip repeatedly, and the inverter may not recover or reset automatically. If you've isolated and restarted the inverter multiple times and it continues to fail within minutes of starting, this suggests an external fault that requires investigation. Contact us immediately — we may need to engage your DNO (distribution network operator) to investigate the supply fault. Grid-side faults typically involve voltage, frequency, or earth issues that are beyond inverter control and require utility-level diagnosis.

Summary: If there is any visible sign of heat, damage, arcing, smoke, or water — call 999 first, then us. If your system has stopped working entirely and you rely on it for essential services, call us for urgent same-day attendance. For fault codes, error lights, or reduced output without physical signs, our standard repair service is usually appropriate — but if you're unsure, call us and we'll advise.

What to do before the engineer arrives

Isolate at the consumer unit

If you haven't already, switch off your solar system at the consumer unit (the main circuit breaker panel). This is the safest position for both you and the engineer while the fault is being investigated. Your system will not generate during darkness anyway, and this removes any live electrical risk during diagnosis.

Safely photograph fault indicators and error codes

If your inverter or battery is displaying an error code, fault light, or unusual status message, photograph it clearly. Include the device brand name and model visible in the photo if possible. Also photograph any physical signs: discolouration, loose connectors, water stains, or unusual positioning of wiring. These photos help the engineer prepare for the visit and order parts if needed. Do not open any enclosures or attempt to access circuit boards.

Have system information ready

Gather the following information before the engineer arrives (you can usually find this on labels attached to the inverter and battery, or in installation documents):

• Inverter brand and model — usually printed on the front panel

• Battery system brand and model — if you have storage

• Any error code or status message displayed on the inverter screen or app

• When the fault started — today, yesterday, after a power cut, or after a software update

• Any recent changes — new appliances, firmware update, or service visit

What NOT to do

In an emergency situation, it's easy to make the fault worse. Please avoid:

✗ Don't open the inverter or battery enclosure. These contain high-voltage components and your safety is at risk.

✗ Don't attempt to restart the system repeatedly if there's a burning smell. Each restart attempt can worsen internal damage.

✗ Don't disconnect or adjust wiring yourself. If a connector is loose, you can photograph it, but reconnection should wait for the engineer.

✗ Don't switch systems between chargers or inverters. If you have multiple systems, keep each isolated at its own isolator or consumer unit switch until the engineer has assessed.

What's included in the emergency callout

The £295–£449 emergency callout fee covers everything involved in diagnosing and stabilising your system. Here's what you get:

01. On-site fault diagnosis

Full system assessment: fault log review, live voltage and current readings, physical inspection of all wiring, connectors, and components. We identify the root cause, not just the symptom.

02. Repair where possible on first visit

Minor repairs, adjustments, and configuration fixes are carried out during the visit — reconnecting loose connectors, correcting settings, firmware recovery, clearing protection trips where safe to do so.

03. Written report and next steps

After the visit, you receive a written report of findings, actions taken, and a clear recommendation for any further work required — with itemised costs before any parts are ordered.

04. Parts ordering and follow-up

If replacement components are needed, we order them and arrange a follow-up visit to fit. You agree the cost in advance. The initial callout fee is not charged twice for the follow-up repair visit.

Travel time is included: The £295–£449 fee covers our engineer's travel, time on-site, and the report. For locations far from Yorkshire, a mileage charge may apply — we confirm this at booking. You will always know the full cost before the visit, and no additional charges are added without your agreement.

FAQ

Emergency repair questions

How quickly can you respond?

Same day for most of the UK. Call or book before noon for the strongest chance of a same-day visit. For safety-critical situations — burning smell, arcing, smoke — isolate at the consumer unit and call 999 first, then contact us.

What does the emergency callout fee include?

The £295–£449 callout fee covers travel, on-site diagnosis, and minor repairs or adjustments carried out during the visit. If replacement parts or extended labour are required, we quote separately before proceeding. You'll never receive a bill you haven't agreed to.

Is my system safe to leave running while I wait?

If you smell burning, see arcing, or notice smoke or discolouration around any enclosure, isolate at the consumer unit immediately and call 999. Do not open any enclosures. For fault codes, reduced output, or battery issues without physical signs of danger, it is generally safe to leave the system in its current state while you wait for an engineer.

Do you offer weekend and evening emergency callouts?

Yes. We operate weekend and evening emergency callouts for safety-critical situations — burning smell, arcing, battery swelling, water ingress, or complete system failure. These are treated as priority and may incur a weekend/evening premium on top of the standard £295–£449 callout fee. Contact us directly to book an out-of-hours emergency visit and we'll confirm the full cost including any surcharge.

Is the diagnostic fee offset against the emergency callout?

If a remote diagnostic identified a fault that needs on-site emergency repair, the remote diagnostic fee is offset — you won't be charged twice. The engineer visit will focus on the specific fault identified, keeping costs and time on-site to a minimum. Contact us with your diagnostic reference and we'll confirm the arrangement at booking.

What areas do you cover for emergency callouts?

We cover all of the UK for emergency callouts, with same-day availability for most locations. We're based in Yorkshire, so we can often reach the North and Midlands within 2–3 hours. For southern England and Scotland, same-day response depends on location and callout time — booking before noon gives the best chance. A mileage charge may apply for locations far from our base; we confirm all costs at booking before the visit is confirmed.
