Learn about Tigo Energy Error Code 310 DC, its meaning, causes, and solutions for troubleshooting.
Error Code 310 DC typically indicates a communication issue between the optimizer and the inverter. This can affect the performance of your solar system.
To troubleshoot, check the connections between the optimizer and inverter. Ensure all wiring is secure and inspect for any visible damage.
The Tigo Energy 310 DC fault code indicates a problem detected in the DC circuit, often linked to insulation resistance issues or ground faults. The inverter monitors parameters such as string voltage and insulation resistance (RISO). If the measured resistance falls below acceptable thresholds, the inverter will trigger the 310 DC fault to protect both the system and the utility grid from potential damage or safety hazards. Ground faults can occur due to moisture ingress, damaged cables, or faulty components, leading to unsafe operating conditions.
Homeowners may notice their Tigo Energy optimizer displaying a persistent fault 310 DC on the monitoring app. This may be accompanied by a drop in energy production, as the optimizer may be unable to function correctly. LED indicators on the optimizer may show a steady red light, indicating a fault condition.
Always consult a licensed electrician or certified solar installer when diagnosing or repairing electrical components of your solar system.
Regular maintenance should include periodic checks of insulation resistance and visual inspections of all electrical connections. Ensure that the system is installed according to NEC standards to minimize the risk of ground faults. Additionally, consider using surge protection devices to safeguard against overvoltage events.
