Learn about Victron Energy Error Code 122, its meaning, causes, and solutions for troubleshooting.
Error Code 122 typically indicates a specific fault in the Victron Energy system. It is essential to refer to the user manual for detailed diagnostics.
To troubleshoot Error Code 122, check the connections and settings of your Victron Energy device. Ensure all components are functioning correctly and reset the system if necessary.
Error 122 typically signifies an insulation resistance fault or ground fault detection within the inverter's DC circuit. The inverter's internal logic continuously monitors insulation resistance (RISO) to prevent potential hazards such as electric shock or fire. If RISO falls below a predetermined threshold, the inverter triggers this fault to protect both the system and the user. Ground faults can occur due to moisture ingress, damaged wiring, or degraded insulation, leading to unsafe operational conditions. The inverter may also detect overvoltage situations or internal component failures, prompting the fault code to appear as a safety precaution.
Users may observe the inverter displaying Error 122 on the LCD or monitoring app. LED indicators may flash in a specific pattern, indicating a fault condition. Additionally, there may be a noticeable drop in energy production, and the inverter may not be feeding power into the utility grid.
Always consult a licensed electrician or certified solar installer when diagnosing or repairing electrical systems to ensure compliance with safety regulations and standards.
To prevent future occurrences of Error 122, ensure regular maintenance of the solar array and inverter, including periodic insulation resistance testing. Verify that all connections are properly secured and that the system is grounded according to NEC standards. Keep the inverter firmware updated and monitor the system's performance regularly to catch any anomalies early.
