Solar repair and fault finding
When a solar system stops making power, the cause can be on the roof, in the loft or inside the inverter. We test the whole system, find the fault and fix it. We repair systems that we installed and systems that other companies installed.
Signs your system needs a repair
- The inverter shows an error code or a red or orange light
- The monitoring app shows zero or very low output on a sunny day
- An isolator or breaker keeps tripping
- The battery does not charge, or empties too fast
- A panel is cracked, scorched or loose
- The app has stopped updating
What we check
- Inverter error logs and settings
- Each panel string, for voltage, current and insulation faults
- DC and AC isolators, connectors and cable runs
- Battery health and communication with the inverter
- Monitoring connection and Wi-Fi dongle
- Panels and mounting for damage

Questions
Is it safe to touch the inverter?
Follow the shutdown steps on the label next to your inverter. Do not open the inverter or touch panels or cables. If you see smoke, sparks or a burning smell, leave the area and call 999.
Will a repair affect my warranty?
We follow each manufacturer's repair procedures for the brands we are accredited for. If your system is still under warranty, tell us when you book, and we will check what the warranty requires.
What if the system is completely down?
Call our 24/7 emergency line on 020 8453 2283. See Emergency call-outs.
