Troubleshooting: Common Symptoms (Topic 3) in Module 6 – Solar-PV-NABCEP-Associate (BG)

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

  1. Safety first: follow procedures and de-energize when needed.
  2. Confirm the simplest conditions first (sunlight, disconnect positions, breakers).
  3. Compare measurements to expected configuration.
  4. Use fault codes and documentation to guide next checks.
