Learn about KLNE Error Code 22, its meaning, causes, and solutions for isolation faults.
Error Code 22 indicates an isolation fault in the system. This typically requires a Riso check to diagnose the issue.
To resolve an isolation fault, perform a Riso check and inspect the wiring for any damage or disconnections.
The fault 22 indicates an isolation fault, specifically related to the RISO (insulation resistance) check. This occurs when the inverter detects that the insulation resistance between the DC input and ground has fallen below acceptable levels. The inverter employs a ground fault detection mechanism that continuously monitors the insulation integrity. When the RISO measurement indicates a potential ground fault, the inverter enters a protective mode to prevent electrical hazards, including shock and fire risks. This is crucial for maintaining safety standards and ensuring the longevity of the system.
Always ensure that a licensed electrician or certified solar installer performs any electrical work on the system to maintain compliance with safety standards and the National Electrical Code.
To avoid future occurrences of isolation faults, ensure regular maintenance checks of the solar array and inverter. Inspect cables for wear and tear, and replace any damaged components immediately. Implement protective measures against environmental factors, such as surge protectors, and ensure proper system practices are followed.
