Solar Inverter Issues: Warning Signs, Monitoring Errors, and Next Steps
- The inverter is critical — a failed inverter usually means zero production.
- Warning lights and monitoring errors are common first signs.
- String inverters and microinverters fail in different ways.
- Inverters often have warranties — preserve documentation.
- Do not open inverter enclosures.
- Do not attempt electrical solar repairs, inverter repairs, or wiring work yourself.
- Do not climb on the roof to inspect or clean solar panels — roof and electrical hazards are real.
- Do not open inverters, combiner boxes, disconnects, or battery enclosures.
- If you see scorch marks, smoke, burning smell, or active electrical damage, contact your utility and emergency services.
- Solar systems remain energized in daylight even when the main breaker is off.
What the inverter does
Panels produce DC power; the inverter converts it to AC power your home uses. String inverters convert from a string of panels. Microinverters convert at each panel. Hybrid inverters also manage batteries.
Common warning signs
Red or yellow lights on the inverter, error codes in the monitoring app, sudden drops to zero production, breaker trips on the solar circuit, or burnt smells around the inverter location are all signals to schedule professional service.
What to do — and not do
Note the error code, take a photo of any warning lights, and check the monitoring app. Do not open the inverter, combiner box, or disconnects. Contact your solar contractor or the original installer with the information.

Frequently asked questions
How long do solar inverters last?
String inverters often last around 10–15 years; microinverters are designed for longer. Warranties vary by manufacturer.
Can I reset my inverter?
Some manufacturers document a controlled shutdown and restart procedure. Follow the documentation, or ask a contractor — improper handling can be unsafe.
Will the utility know my system is down?
Not necessarily. Monitoring alerts you. The utility focuses on grid stability, not your individual production.
Does HSRC repair inverters?
No. HSRC helps connect homeowners with local solar contractors for diagnosis and service.
