Learn about SolarEdge error code 193, its causes, and how to resolve it effectively.
Error code 193 typically indicates a restart request issue. This can occur due to communication problems or system faults.
To troubleshoot, check the inverter's connections and ensure all components are functioning properly. Restarting the inverter may also help.
The inverter triggers fault 193 primarily as a safety measure. This occurs when the inverter detects a ground fault or an insulation resistance (RISO) measurement that falls below the acceptable threshold. Ground faults can arise from damaged wiring or moisture intrusion, which compromises the safety of the system. The inverter also continuously monitors grid conditions; if it detects that the grid voltage or frequency is outside of specified limits, it will shut down to protect both itself and the connected array. Additionally, internal overcurrent detection mechanisms can trigger this fault if the inverter senses conditions that may lead to damage or unsafe operation.
The SolarEdge inverter displaying error 193 typically indicates a restart request due to a fault condition. Users may observe the LED indicator showing a blinking red light or a solid red light, depending on the specific fault state. Additionally, the monitoring app may report a production drop or a system offline status, indicating that the inverter has disconnected from the grid or is unable to operate.
Always ensure that any troubleshooting or repairs are conducted by a licensed electrician or certified solar installer to maintain safety and compliance with local electrical codes.
To avoid encountering fault 193 in the future, regularly inspect the solar array and inverter for signs of wear or damage. Ensure that all connections are secure and free from corrosion. Schedule routine maintenance checks, including insulation resistance testing, to ensure the system remains in optimal condition. Additionally, ensure that the system complies with the latest NEC standards and manufacturer guidelines.
