Learn about Growatt Error Code 122, its meaning, causes, and how to fix it effectively.
Error Code 122 indicates a communication fault within the inverter system. This can affect performance and monitoring capabilities.
To troubleshoot, check all connections and ensure the inverter is properly communicating with the monitoring system. Restarting the inverter may also help.
Error 122 typically indicates a communication fault between the inverter and the monitoring system. This can occur due to several factors, including issues with the communication cable, firmware problems, or network connectivity. The inverter relies on continuous data exchange to function optimally and report performance metrics. If the inverter cannot communicate effectively, it may trigger this fault to prevent further operational issues or system damage. The underlying electrical logic involves the monitoring of signal integrity and response times, which, when disrupted, can indicate potential faults in the system.
Upon encountering Error 122 on a Growatt inverter, users may observe a steady red LED indicator or a flashing pattern indicating a communication fault. Monitoring apps may display alerts regarding communication failures, and system performance may drop significantly, showing reduced or zero energy production.
Before attempting any repairs or inspections, it is crucial to disconnect the inverter from the utility grid and follow all safety protocols. Always consult a licensed electrician or certified solar installer for any electrical work to ensure compliance with local codes and safety standards.
To avoid encountering Error 122 in the future, conduct regular inspections of communication cables and connections. Ensure the inverter's firmware is kept up-to-date and perform routine checks on the system's grounding to comply with NEC standards. Additionally, maintain a clear distance from potential sources of electrical interference and consider implementing surge protection devices where necessary.
