Learn about Sungrow Error Code 013, its causes, and how to fix grid overvoltage issues effectively.
Error Code 013 indicates a grid overvoltage condition detected by the inverter. This can lead to system shutdown to protect equipment.
To resolve grid overvoltage, check local grid voltage levels and consult with your utility provider. Adjustments may be necessary to ensure compliance.
Sungrow inverter fault 013 indicates a grid overvoltage condition, which occurs when the average voltage exceeds the inverter's maximum allowable limits for a duration of 10 minutes. This can happen if the utility grid experiences voltage spikes, often due to high demand or infrastructure issues. The inverter is designed to protect itself and the solar array by disconnecting from the grid under these conditions to prevent damage. Voltage sensing components within the inverter continuously monitor the AC output voltage and trigger this fault when unsafe levels are detected, ensuring compliance with NEC standards for grid-tied systems.
Homeowners may notice the inverter display showing fault 013, along with a steady red LED indicator. The monitoring app may send alerts indicating a grid overvoltage condition, and solar production may drop significantly, often to zero, during this fault condition.
Always ensure that any troubleshooting or repairs are performed by a licensed electrician or certified solar installer to maintain safety and compliance with local codes.
To avoid encountering fault 013 in the future, regularly maintain the inverter and its connections. Schedule periodic inspections of the AC output circuit and ensure that the inverter settings are appropriate for local grid conditions. Additionally, consider installing surge protection devices to safeguard against voltage spikes from the utility grid.
