5. Continue until you find the string that triggers the alarm. Trace
back the faulted string to find any leakage to Earth Ground.
Recommended solutions:
1. Restart inverter by turning both AC and DC switches OFF. Wait for
1 minute for all energy to discharge and turn both switches ON.
2. If inverter cannot clear fault, replace inverter.
