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

Dennis Brown · May 2026 Trustpilot

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)

Tony Deacon · May 2026 Trustpilot

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

Phill · May 2026 Trustpilot

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.

Mr Machin · May 2026 Trustpilot

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.

Christopher · Apr 2026 Trustpilot

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!

What's included at £75

Root cause identification

We review your fault log, generation history, and live readings to pinpoint exactly what's wrong — not guess.

Settings validation

CT clamp direction, export limit, charge schedules, tariff configuration — corrected during the session where safe to do so remotely.

Written action plan

A clear written report of what was found, what was done, and any on-site work required — with an honest cost estimate if needed.

Follow-up path

If parts or a site visit are needed, you'll know exactly what they are before committing. No blank cheques.

How it works
01

Book and describe the fault

Fill in the booking form with what you're seeing — fault codes, lights, when it started. We'll confirm a time, usually the same day.

02

We connect and diagnose

During the 30-minute session we access your monitoring data and inverter readings, identify the fault, and apply any safe remote fixes.

03

Written report and next steps

You receive a written summary of what was found, what was done, and a clear recommendation — with honest costs if further work is needed.

When a remote diagnostic is the right choice

System producing less than expected but no obvious fault — likely a configuration or monitoring error

Battery not charging from solar or overnight — usually a CT clamp direction error or schedule misconfiguration

Monitoring app showing incorrect data, reversed import/export, or offline readings

Fault code on inverter or battery — we'll identify what it means and whether it needs a site visit

Export limit settings incorrect after DNO change or smart meter installation

Not sure what's wrong — start here before committing to an on-site visit

Safety note: If you smell burning, see arcing, or notice smoke or discolouration around your inverter or battery, isolate at the consumer unit immediately and call 999. Do not attempt to open any enclosures. For these situations use our emergency solar repair service.

What we check during a remote diagnostic

During your 30-minute session, we conduct a comprehensive review of your solar PV and battery system. Here's exactly what we examine:

Inverter fault logs and error history

We review every error code, warning, and fault recorded by your inverter, tracing patterns and identifying which ones need attention and which are normal transient events.

Generation data analysis

Daily, weekly, and monthly generation patterns are cross-referenced against weather, seasonal norms, and system specification to spot underperformance or anomalies.

Battery state of charge and cycling

We examine charge/discharge cycles, resting voltage, depth of discharge patterns, and state of health indicators to assess battery condition and usage patterns.

CT clamp configuration and direction

One of the most common faults — CT clamps installed backwards cause reversed import/export readings. We validate direction and orientation against live data.

Export limit and DNO compliance

We verify export limit settings match your DNO agreement, especially following smart meter installation or changes to grid connection terms.

Charge and discharge schedule review

Battery charging and export schedules are checked against your tariff, ensuring optimal alignment with off-peak rates and export pricing.

Firmware version and known issues

We check inverter and battery firmware versions against manufacturer known issues database, identifying whether updates or workarounds are needed.

Monitoring platform connectivity

We verify data accuracy between your inverter, monitoring app, and our platform, identifying communication gaps, data lag, or sensor failures.

Common faults we diagnose remotely

CT clamps installed backwards

This is one of the most frequent faults we encounter. When CT (current transformer) clamps are reversed, your system reports export as import and vice versa. Your battery may appear to be discharging when it's actually charging from solar, and your monitoring app shows backwards flow. We can confirm this with live data and walk you through the fix — usually a 5-minute correction that doesn't require an engineer visit.

Learn more about monitoring data accuracy issues →

Export limits set incorrectly

After smart meter installation or DNO agreement changes, export limits often remain at old settings. This can cap your system to 0 kW export, prevent battery discharge optimization, or breach your DNO agreement. We validate your settings against your current agreement and correct them remotely if needed.

Troubleshoot export limit problems →

Battery charge schedules not aligned with tariff

Your battery may be charging during peak hours when electricity is expensive, or discharging when prices are low. Misaligned schedules waste export revenue and increase grid import costs. We review your tariff and adjust charge/discharge windows to maximize savings remotely.

Fix battery charging issues →

Monitoring app showing reversed or incorrect data

Sometimes your app displays inverted import/export values, shows offline data despite the inverter being online, or reports generation figures that don't match live readings. We trace the data path from inverter through monitoring platform to your app and identify where the disconnect is occurring.

Resolve monitoring connectivity issues →

Inverter in standby mode due to grid frequency drift

Grid frequency fluctuations outside normal range (49.8–50.2 Hz) can cause your inverter to disconnect and enter standby. This usually resolves itself, but persistent standby indicates a grid issue or inverter sensitivity setting that needs validation. We check your settings and advise whether contact with your DNO is needed.

Check system performance and grid stability →

Battery not charging from solar due to mode misconfiguration

Your battery may be set to manual charge only, or configured to ignore solar surplus during certain hours. This prevents self-consumption and wastes potential savings. We review your operating mode and adjust schedules so your battery charges intelligently from available solar.

Get your battery charging again →

What happens after your diagnostic

Every diagnostic concludes with a clear next step. We don't leave customers with open questions or unclear paths forward. Here are the three most common outcomes:

✓ Fault resolved remotely

Most common for configuration issues. We correct CT clamp direction, export limits, charge schedules, or other settings during the session. You receive a written report documenting the changes and your system returns to normal performance — usually within the 30-minute session window.

No further action needed

→ On-site visit required

If physical work is needed — faulty hardware, physical installation errors, parts replacement — we tell you exactly what's required and the cost before you commit. On-site repairs start from £245, and parts are pre-ordered to ensure the visit is efficient and same-day completion where possible.

Clear quote, no surprises

⚠ Warranty claim recommended

If we identify a manufacturing defect or failure covered under warranty, we document the fault, prepare evidence, and provide all the documentation you need to file a claim with the manufacturer or installer. We handle warranty support at every step.

We provide all documentation

The diagnostic fee is never wasted: Whether the fault is fixed remotely, requires a visit, or needs a warranty claim, the £75 diagnostic fee always translates into faster resolution, fewer wasted site visits, and honest costs upfront. We treat your time and budget with the same care we treat our own.

FAQ

Questions about the remote diagnostic

We connect to your inverter and monitoring system, review your generation history, fault log, and live readings. We identify the root cause of the fault, walk you through what we find, and apply any settings corrections that are safe to make remotely — CT clamp direction, export limits, charge schedules. You receive a written report summarising the fault, what was done, and any recommended next steps.
If on-site work is needed, we tell you exactly what is required and what it will cost before you commit. The £75 diagnostic fee is not wasted — it means any engineer visit is precisely targeted, with the correct parts identified in advance. On-site solar system repairs start from £245.
All major brands: SolarEdge, GivEnergy, Sunsynk, Growatt, Solis, Enphase, Fronius, Fox ESS, Huawei, Tesla Powerwall, SiEnergy, AlphaESS, Sofar, and most others. If you are unsure whether your brand is supported, contact us before booking.
Yes, you'll need to be available during your booked 30-minute slot. We'll call at your scheduled time, walk you through what we're finding in real time, and may need you to check settings on your inverter or answer questions about how the system has been behaving. This interaction ensures we get the full picture and can make recommendations you understand and trust.
Yes, for most issues. We can review state of charge, cycling patterns, charge/discharge rates, firmware versions, and error logs to diagnose battery configuration and software faults. However, internal battery hardware defects (cell failure, BMS issues causing physical damage) require on-site inspection. We'll tell you which category your issue falls into and what comes next.
Have your inverter and battery brand/model ready — you'll find these on the physical units or in your installation paperwork. A clear description of what you're seeing (e.g., fault code, reversed import/export in app, battery not charging) helps us prepare. You don't need login credentials — we'll ask for monitoring platform access during the session, or you can grant temporary read-only permissions if your system allows it. If you have recent screenshots of error codes or unusual readings, keep those handy to share during the call.
