Learn about EcoFlow Error Code 4, its meaning, causes, and solutions for grid undervoltage issues.
Grid undervoltage Code 4 indicates that the voltage from the utility grid is below acceptable levels. This can lead to system shutdowns to protect the inverter.
To resolve this issue, check the grid voltage levels and ensure they meet the inverter's specifications. If the problem persists, consult a professional technician.
This error occurs when the inverter detects that the voltage from the Utility Grid has fallen below the minimum operational threshold, typically set by the manufacturer. The inverter continuously monitors the AC voltage input and utilizes internal voltage sensing components to ensure it operates within safe limits. If the voltage is too low, the inverter automatically disconnects to prevent damage to its internal circuitry and to maintain safety protocols. This behavior is in line with the National Electrical Code (NEC) requirements for protective devices to ensure safe operation under abnormal grid conditions.
When the EcoFlow SHP2 inverter displays Error 4, users may notice a red LED indicator flashing or a notification on the monitoring app indicating grid undervoltage. Additionally, there may be a drop in power production, with the inverter ceasing to supply energy to the home or grid, particularly noticeable during nighttime when the system relies on stored energy.
It is essential to engage a licensed electrician or certified solar installer for any troubleshooting or repair work to ensure compliance with safety regulations and to mitigate the risk of electrical hazards.
To prevent future occurrences of grid undervoltage, regularly inspect and maintain all electrical connections and the grounding system. Ensure that the inverter settings are updated in accordance with any changes in local grid regulations. Consider using a voltage stabilizer if your area frequently experiences voltage fluctuations.
