If your system has an active fault or isn't performing as expected, a remote diagnostic gets to root cause faster than reading guides.
Book your free diagnosticSolar not working? Start hereRon was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
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.
Ronald was great to help me sort out my giv energy inverter issue since company has gone bankrupt in april 26.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.
Called back within a day and gave good advice.
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
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.
