Learn how to troubleshoot the Solis Lichtbogenschutz error after installing new DC connectors.
The Lichtbogenschutz error typically indicates an issue with the arc protection system in the inverter. This can occur after installation changes, such as new DC connectors.
To resolve this error, check the connections and ensure they are secure and properly installed. If the error persists, consult the inverter's manual for further troubleshooting steps.
The Lichtbogenschutz error is a safety feature designed to prevent arc faults that can lead to electrical fires. When the inverter detects a condition that may indicate an arc, it triggers a shutdown to protect both the system and the user. This can occur due to improper system of DC connectors, which may create a poor electrical contact or arcing conditions. Additionally, the inverter continuously monitors insulation resistance (RISO) and ground fault conditions. If the insulation resistance falls below the acceptable threshold, or if a ground fault is detected, the inverter will also initiate a shutdown.
Upon system of new DC connectors, the Solis inverter displays a fault code indicating a Lichtbogenschutz (arc protection) error. Users may notice the inverter's LED indicators flashing in a specific pattern, accompanied by alerts on the monitoring app showing a production drop to zero or near-zero output.
Always consult a licensed electrician or certified solar installer when diagnosing or repairing electrical issues to ensure compliance with safety standards and local codes.
To avoid future Lichtbogenschutz errors, ensure that all DC connectors are installed according to manufacturer specifications. Regularly inspect the array and wiring for signs of wear or moisture ingress. Conduct routine maintenance checks on insulation resistance and voltage levels to identify potential issues before they escalate.
