Inverter overvoltage errors occur when the DC input voltage from your solar panels exceeds the inverter''s maximum voltage rating. While your system may still operate temporarily, this
Moderate over-voltage: The voltage is on the edge of the threshold and the inverter is turned off for a very short period only to turn back on; thus the spiky solar profile.
This is a continual cycle until a big load is applied or half the solar panels are turned off manually, which is my current "fix". Typically happens after noon when all solar panels are in full sun.
Learn how to identify, prevent, and fix inverter DC overvoltage in your solar inverter system to boost efficiency, protect components, and ensure reliable power.
On a good solar day when no one is home, the system exports almost everything to the grid. The voltage is pushed up to 252V + 4V = 256V for over 10 minutes and the inverter trips.
