Causes of DC overvoltage in photovoltaic inverters

On sunny days, Inverter switches off when DC voltage gets too high?

At other times of the day, when the battery reaches 100%, the DC voltage is not as high and the inverter does not switch off. Amps do not rise above 10.3A on each string, at any time. I
