What is the minimum string size of a PV inverter?

The minimum string size, then, is 15 modules. The maximum string size is the maximum number of PV modules that can be connected in series and maintain a voltage below the maximum allowed input voltage of the inverter. The Module Voc_max is calculated using the coldest temperature when the modules produce the highest expected voltage.

How many panels can an inverter have in a string?

Take your inverter’s maximum DC input voltage. Divide it by your adjusted Voc. This gives you the maximum number of panels you can have in a string. For instance, if your inverter’s max input is 1000V: You can’t have a part of a panel, so round down to the nearest whole panel. In this case, you could have up to 22 panels in a string. 4.
