Learn about Huawei Error Code 2064, its meaning, causes, and solutions for your SUN2000 inverter.
Alarm 2064 typically indicates a communication issue within the inverter system. This may require checking connections or firmware updates.
To troubleshoot, start by reviewing the inverter's manual for specific alarm codes. Ensure all connections are secure and check for software updates.
Fault 2064 is triggered when the inverter detects an insulation resistance measurement that falls below the manufacturer's specified threshold. This is a critical safety feature designed to prevent electrical shock hazards or equipment damage. The inverter continuously monitors the insulation resistance (RISO) between the DC side and ground. If a ground fault occurs, the system identifies an unintended current pathway, leading to a fault condition. This can be due to moisture ingress, damaged cables, or faulty components within the inverter itself.
The Huawei SUN2000 inverter displaying fault 2064 typically results in a red LED indicator, signaling an alarm state. Users may also notice a drop in solar production metrics on the monitoring app, with alerts indicating a fault condition. If the inverter is equipped with a display, it may show specific error messages related to ground faults or insulation issues.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical issues to ensure safety and compliance with local codes.
To prevent future occurrences of fault 2064, ensure regular maintenance checks on the inverter and array. This includes inspecting wiring for wear, checking insulation resistance annually, and ensuring that all connections are secure and free from corrosion. Additionally, consider installing protective enclosures for electrical components to mitigate environmental impacts.
