What Can You Ask Us About?
You do not need to know the technical language. Tell us what the system is doing, include any warning code you can see and we will help point you in the right direction.
Inverter Fault Codes
“What does this red light or error code mean?”
No Generation
“My solar has completely stopped producing electricity.”
Battery Storage
“Why is my battery charging or discharging differently?”
FIT & Export
“Will this change affect my Feed-in Tariff or export payments?”
When online advice is not enough
Some Solar Faults Need Proper On-Site Testing
Some questions can be answered from the information you provide, but no remote assessment can electrically test your system, inspect hidden wiring or confirm that an installation is safe.
Remote advice is general guidance only and does not replace professional testing or inspection where an electrical or equipment fault is suspected.
Contact us directly if:
- The solar system has stopped generating completely
- Fuses or circuit breakers repeatedly trip
- A persistent inverter fault code will not clear
- You smell burning or see visible heat damage
- You suspect an electrical or fire-safety risk
- There is damaged DC cabling or connectors
- The panels or inverter have suffered physical damage

Frequently asked questions
Ask Mr Solar FAQ
Can you diagnose my solar system from a message?
We can often narrow down the likely cause from the symptoms, fault code, monitoring screenshots and equipment details, but some faults require electrical testing or an engineer on site before a diagnosis can be confirmed.
Should I reset my inverter?
Only follow the manufacturer’s published user restart procedure. Do not open the inverter or disconnect solar DC connectors.
Can I ask about a system Mr Solar did not install?
Yes. Yes. We provide professional repair and Rescue support for suitable systems installed by other companies as well as our own installations.
Can I ask about Feed-in Tariff or export payments?
Yes. We can explain general FIT, generation-meter and export issues. Specific metering or compliance questions may require us to review your system paperwork.
What information should I provide?
The inverter or battery make/model, exact fault code, postcode, when the issue started and what the monitoring app is showing are all helpful.
Ask Mr Solar
Ask the question. If it needs testing, we’ll take it from there.
Send your question to our Norfolk team for guidance, or book professional support when the problem needs testing or an on-site visit.
