Emergency solar repair same-day response for urgent faults
For urgent faults that can't wait — complete system failure, safety-critical alarms, EPS not activating, or faults appearing before an important event. We aim to respond the same day, usually within hours.
If you smell burning, see arcing, or notice smoke: isolate at the consumer unit immediately and call 999. Do not open any inverter or battery enclosures. This service is for electrical faults — not fire emergencies.
Same-day availability · On-site diagnosis and repair · Written report included
Book emergency repair →Tell us what's happening and we'll confirm a same-day slot.
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 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):
What NOT to do
In an emergency situation, it's easy to make the fault worse. Please avoid:
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:
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–£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.
Emergency repair questions
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.
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.
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.
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.
If you've already paid for a remote diagnostic (£75) and it identified a fault requiring 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.
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.
