How do you calculate a string size for an inverter?

Calculate the Maximum String Size 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.

How many strings can be connected to a solar inverter?

This inverter has 2 MPPT trackers, so a total of 2 strings can be connected to the inverter. We know that there can only be 13 modules maximum installed. We can have one MPPT with 6 modules in a string and the other at 7 modules in a string. Check out UpTop Solar String Sizing Tool that does this for you!
