Ron diagnosed the problem remotely - efficiently and order the part identified as the fault - this part came directly from to me and Ron visited within a few days and within the hour corrected the problem and since everything has been excellent -highly recommended - very pleasant manner and lovely to work with .

Wow... a firmware update to my inverter sent the whole system into meltdown – the battery discharged, and the house seemed to be drawing power, and the solar, who knows where that was going? Aghhh... A short email exchange with Roland and Solar Tech Support sorted the problem... the firmware had reversed a setting (from when it was installed), and the CT clamp needed to be reversed. As soon as I had done that, the world returned to normal. Thanks, Roland; there is no way I would have come to that conclusion. Would I recommend them? You bet! Worth the fee? You bet, again!
Solar Tech Support answered my initial enquiry swiftly. They provided remote support to establish what the issue was, and through their experience and network, managed to get my clients system back online. Once the system was online, STS managed to diagnose the main issue to get the ac coupled inverter and battery back online, a battery repair was required. A site visit was organise and within a few days, the system was tested and back up and running. This has saved my client, and probably myself huge costs and inconvenience now the system is back online and working correctly. Would highly recommend.
Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution
Made contact for assistance with my GiveEnergy battery that wasn't discharging. Ronald looked at my issue the same day, identified the root cause with a clear explanation of what was going on along with some options on how to remediate the issue. So far my battery is now working and keeping my fingers crossed that it stays this way. Ronald is a very experienced and knowledgeable engineer and I would recommend.
Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate
Inverter not starting, battery completely unresponsive, or no generation at all on a clear day
Your backup power failed during a grid outage. A critical safety and commissioning issue — do not leave this unchecked
Isolation fault, arc fault detection, earth leakage — alarms that indicate a potential safety risk, not just a configuration error
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
A battery importing aggressively from the grid without instruction can indicate a BMS fault or protection event in progress
For faults that can wait a day or two, a free remote diagnostic is the right starting point
The callout fee includes a full on-site diagnostic — fault log review, live readings, physical inspection of wiring, connections, and components.
Minor repairs and adjustments — settings corrections, connection issues, firmware recovery — are carried out during the visit within the callout fee.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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):
In an emergency situation, it's easy to make the fault worse. Please avoid:
The £295–£495 emergency callout fee covers everything involved in diagnosing and stabilising your system. Here's what you get:
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.
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.
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.
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–£495 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.
Book now and we'll confirm a same-day slot. Tell us what's happening — fault codes, lights, when it stopped — and we'll come prepared with the right parts and test equipment.
