Troubleshooting: Common Symptoms
Troubleshooting is a structured process: observe symptoms, gather data, isolate possible causes, and verify fixes.
Examples of symptoms
- Inverter will not start
- Low production
- Intermittent shutdowns
- Fault codes (ground fault, arc fault, over/under voltage)
General approach
- Safety first: follow procedures and de-energize when needed.
- Confirm the simplest conditions first (sunlight, disconnect positions, breakers).
- Compare measurements to expected configuration.
- Use fault codes and documentation to guide next checks.
