Solar System Diagnosis
Check 'Solar Supply Main Switch' is ON; If fault code remains you will require on-site diagnosis by a trained Swift Solar Repairs technician. Contact us immediately to resolve this issue.
AC grid outside the permissible safe limit! This identifies an issue with the grid supply to your property which can be dangerous, your inverter has responded by shutting down. Contact us immediately to resolve this issue.
Inverter Over Temperature: This fault indicates the inverter internal temperature is exceeding safe limits, this is often shown on hot days unless the inverter is incorrectly reading a high temperature. Acknowledge fault code, shutdown inverter, restart after 2 mins; If fault code remains you will require on-site diagnosis by a trained Swift Solar Repairs technician. Contact us immediately to resolve this issue.
Internal CPU Failure: Communication between the master and slave CPU has failed
Isolation fault/Ground fault: this indicates voltage has been detected by the earthing system
PV Overvoltage: This fault indicates the array voltage is exceeding safe inverter limits, this is often shown on cold mornings unless the inverter is incorrectly reading a high input voltage and needs to be repaired.
Extreme risk identified! Shutdown inverter immediately, you will require on-site diagnosis by a trained Swift Solar Repairs technician. Contact us immediately to resolve this issue.
Technician Required! Your solar system requires on-site diagnosis from a trained Swift Solar Repairs technician. Contact us immediately to resolve this issue.
