I am confused with the calculation of the main disconnection of a photovoltaic inverter, in the inverter data sheet it is said that the maximum AC output current is 145A, then, as I understood, the way to calculate the OCPD is to multiply this current value by 125%, and the current would be 181.25A and the switch 200A.

But when I review the data sheet, the maximum external AC overcurrent protection is: 225A, how is that possible?

Could someone help me clarify this dobut,

Thank you!
