Incorrect wiring: Faulty or incorrect wiring of the PV array can lead to voltage imbalances or spikes, exceeding the inverter's limit. Faulty inverter components: A malfunctioning component within the inverter, such as a capacitor or sensor, might contribute to the overvoltage condition.
High DC voltage can damage the inverter's internal components, leading to malfunctions or permanent failure. To protect itself, the inverter shuts down when this error occurs. Excessive solar panel voltage: The solar panels might be generating more voltage than the inverter can handle, especially in conditions of high irradiance or low temperature.
Check for shading: Uneven shading on the solar panels can cause voltage imbalances, potentially leading to overvoltage. Ensure that all panels are receiving uniform sunlight. After addressing the potential causes, power on the inverter and monitor the DC bus voltage through the inverter's display or monitoring system.
Inspect the DC wiring: Carefully check all wiring connections between the solar panels and the inverter, ensuring they are tight, secure, and free from damage or corrosion.
What is an Overvoltage Error? Inverters use DC bus capacitors to store electrical energy. When the voltage on the DC bus exceeds the permissible threshold (typically > 400V for 3-phase 220V
