Learn about Schneider XW Pro Error Code 63, its causes, and troubleshooting solutions.
Fault 63 indicates an internal relay error in the Schneider XW Pro inverter. This can affect the inverter's performance and requires troubleshooting to resolve.
To reset the XW Pro, turn off the inverter, wait for a few minutes, and then turn it back on. This may clear temporary faults.
Fault 63 is triggered when the inverter detects an internal relay issue, often linked to electrical logic failures. The inverter continuously monitors conditions such as insulation resistance (RISO) to the ground, ensuring that any leakage current is identified and mitigated. If the RISO measurement falls below acceptable thresholds, or if there is a ground fault detected, the inverter will enter a protective state to prevent damage. This error can also arise from excessive load conditions or improper voltage levels from the solar array, leading to relay malfunction.
Upon encountering Fault 63 on the Schneider XW Pro inverter, users may observe a steady red LED indicator signaling an error state. The monitoring app may display an alert indicating that the inverter has stopped functioning or is in a fault condition. Additionally, there may be a noticeable drop in power production, with the inverter failing to convert DC from the solar array into usable AC power.
Always ensure that a licensed electrician or certified solar installer performs troubleshooting and repairs on the inverter to maintain safety and compliance with local electrical codes.
To avoid encountering Fault 63 in the future, regularly perform maintenance checks on the inverter and associated wiring. Ensure all connections are secure and free from corrosion. Conduct routine insulation resistance testing to identify potential issues before they escalate. Additionally, monitor the output voltage from the solar array to ensure it remains within the inverter's specified limits.
