Learn about Samil Power SolarRiver Error Code 31, its meaning, causes, and solutions for relay faults.
Error Code 31 indicates a relay fault in the Samil Power SolarRiver inverter. This can affect the inverter's performance and may require troubleshooting.
To troubleshoot Error Code 31, check the relay connections and ensure they are secure. If the issue persists, consult the user manual or contact support.
The error 31 is triggered when the inverter detects a fault in the relay system, which is critical for controlling the flow of electricity from the solar array to the utility grid. The inverter continuously monitors insulation resistance (RISO) to ensure safety; a drop below the threshold indicates potential ground faults or insulation breakdowns. If the inverter senses an unsafe condition, it will shut down to prevent damage or electrical hazards, hence the activation of fault 31.
Users may observe the inverter displaying an error 31 on the front panel, often accompanied by a blinking LED pattern indicating a fault condition. Monitoring apps may show a sudden drop in power production or a complete halt in inverter operation, with alerts indicating a relay fault.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical systems to ensure safety and compliance with local regulations.
To avoid future occurrences of this fault, conduct regular maintenance checks on the solar array and wiring, ensuring all connections are secure and free from moisture. Implement routine insulation resistance testing to catch potential issues early and keep the inverter firmware updated to ensure optimal performance.
