If your system has an active fault or isn't performing as expected, a remote diagnostic gets to root cause faster than reading guides.

Despite the fact that I'm situated hundreds of miles away and he knew there'd be no business opportunity from my inquiry, Ron still chased solutions and helped me get an understanding of what I needed to do. I love working with people like this, people with integrity and service at the heart of what they do. I just wish hew was nearer!
My installer put me through Hell with so botched install that you can not imagine Than Ron came , He did not managed to do miracles (because my system components were impossible to work together) and he Gave me a detailed report of what is wrong , why is wrong , why can not be fixed etc. with all the details which I can use in a claim. Without His his help knowledge and attitude I would've been lost
Solar Tech Support is an absolute lifesaver. My solar and battery system stopped working completely, but after one quick phone call, they fixed the problem straight away. The original provider, GivEnergy, has gone into administration, leaving me entirely without support from the original installers. It was a terrible situation on GivEnergy’s part, but thankfully, Solar Tech Support came to the rescue!
Ronald was able to organise a brilliant electrician with extensive experience of GivEnergy systems local to me in the SW. I have now got a fully functioning system and suspect that my electricity bill will be substantially reduced or in credit over a year. Also when said electrician discovered an overvoltage in the my local grid, Ronald prepared a very lucid and comprehensive report of the situation which I have now supplied to my local grid. Cannot recommend Ron and Dan enough.
Called back within a day and gave good advice.
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.
Your solar system has several components working together — panels, an inverter, possibly a battery, and monitoring. Understanding the basics means you can spot problems early, read your monitoring data with confidence, and have informed conversations with your installer.
The inverter converts DC power from your panels into AC electricity your home can use. Learn about MPPT tracking, anti-islanding, grid frequency response, and why the inverter is the most critical component in your system.
Read guide →Battery chemistry, how the BMS protects your cells, charge cycles and degradation, AC vs DC coupling, and what state-of-charge and depth-of-discharge actually mean for your system's lifespan.
Read guide →How data flows from your panels to your phone, what the key figures in your portal mean, why monitoring goes offline, and how to access your system if you've bought a house with solar already installed.
Read guide →The small sensor that tells your inverter what your home is importing and exporting. Why direction matters, what happens when it's backwards, and how to test yours with a kettle.
Read guide →Everything to check when your system has just been installed. Roof sealing, cable labelling, inverter siting, commissioning tests, and the documentation you must receive — MCS cert, G98/G99, EIC.
Read checklist →The grid connection standards that determine how your system connects to the network. Which applies to your system, what it means for export limits, and why your installer needed to notify the DNO.
Read guide →Your system is generating free electricity — but how much of that translates into actual savings depends on your tariff, when you use energy, and how your system is configured. Most new owners leave significant money on the table.
The complete guide to getting the best financial return from your solar and battery system. Self-consumption vs export, tariff selection, battery scheduling, and the settings most people miss.
Read guide →The wrong tariff costs solar and battery owners £200–£500 per year. Covers Octopus Flux, Go, Agile, flat-rate options, SEG export rates, and how to match your tariff to your system configuration.
Read guide →How to get paid for the solar electricity you export to the grid. Which tariffs are available, what your system needs to qualify, and how to check you are receiving the correct payments.
Read guide →How the three-period Flux tariff works, whether it suits your system, how to configure every major inverter brand, and what to do when the BST clock shift breaks your schedule.
Read guide →Why your DNO may limit how much energy your system can export, how inverters enforce the limit using CT clamp data, and what happens when the limit is misconfigured.
Read guide →Solar systems are low-maintenance, not zero-maintenance. Knowing what to check and when means you catch small problems before they become expensive ones — and keep your system performing at its best for 20+ years.
What to check monthly, quarterly, and annually. Panel cleaning, inverter ventilation, battery health, monitoring review, warranty tracking, and when to call an engineer vs when to DIY.
Read guide →What can go wrong when updating inverter or battery firmware — settings resets, stalled updates, version incompatibility, and bricked hardware. When to update and when to leave it alone.
Read guide →Step-by-step shutdown and restart procedure for maintenance, emergencies, and roof work. Covers AC and DC isolation, battery shutdown, and the correct sequence for all brands.
Read guide →What fault codes mean, where to find them, how to read error logs in your monitoring portal, and when a fault code means you need an engineer vs when you can resolve it yourself.
Read guide →One of the most common surprises for new solar owners: your battery probably won't power your house during a power cut unless it has been specifically configured for it. These guides explain why and what you can do about it.
Why systems shut down by default during a power cut, what anti-islanding is, the difference between EPS and UPS, how island mode works, and what you can realistically power from a battery.
Read guide →If your system supports backup but it's not configured, here are the four EPS installation types: single socket, dedicated circuit, manual changeover, and automatic changeover. Pricing from £495 (socket) to £995 (dedicated circuit).
View options →Battery didn't kick in when the grid went down? Full diagnosis steps covering EPS configuration, wiring, neutral-earth bond, and battery reserve settings.
Diagnose →Solar systems are reliable, but they are not infallible. If your monitoring is showing something unexpected, or your inverter has a warning light, these resources will help you work out what's happening.
The guided diagnostic that asks you what you're seeing and routes you to the right fault page. The fastest way to find relevant help.
Start diagnosis →Battery not charging, monitoring offline, system underperforming, inverter red light, export limitation issues — fault-specific guides for the most common UK solar problems.
Browse all problems →Inverter showing an error code? Look up GivEnergy, SolarEdge, Growatt, Sunsynk, Solis, Enphase, Fronius, and Huawei fault codes with plain-English explanations and next steps.
Look up fault codes →New systems occasionally have teething problems — misconfigured settings, reversed CT clamps, firmware bugs, or commissioning oversights. A 30-minute remote diagnostic checks everything and gives you a written report of what's right, what's not, and what to ask your installer to fix.
