Learn how to troubleshoot the Enphase Envoy flashing red lights due to a power surge.
Flashing red lights on the Enphase Envoy indicate a critical error, often due to a power surge. This requires immediate attention to prevent further issues.
To reset your Enphase Envoy, power it down completely and then restart it after a few minutes. This can help clear temporary faults.
The Envoy is designed to monitor and communicate the performance of the solar array and its associated inverters. A power surge can trigger protective mechanisms within the inverter, leading to a shutdown to prevent damage. This can occur if the voltage from the Utility Grid exceeds the inverter's operational thresholds, or if there are abnormal readings detected from the array, such as excessive ground faults or overvoltage conditions. The inverter continuously checks for insulation resistance (RISO) to ensure safe operation; if a fault is detected, it will enter a fault state, indicated by the flashing red lights.
The Enphase Envoy displays all lights flashing red, indicating a critical fault condition. The monitoring app may show alerts related to system performance drops, and the inverter may not be producing power. Homeowners may also notice that the system is offline and not communicating with the monitoring platform.
Always consult a licensed electrician or certified solar installer when performing diagnostic or repair work on solar systems to ensure compliance with local codes and safety standards.
To prevent future occurrences of power surge-related faults, ensure proper grounding of the entire solar array and inverter system. Regularly inspect electrical connections for integrity and cleanliness. Consider installing surge protection devices (SPDs) to mitigate voltage spikes from the Utility Grid. Maintain an optimal array configuration to avoid mismatched panels that can lead to overvoltage conditions.
