Growatt with dual pv input question

[jbernal]

Do both pv inputs have to match in voltage, or wattage, or both?
My reason for asking is that I have 20 panels, and wondering if I should group them as 5 groups of 4 (and have one pv input of 3 groups, one pv input of 2 groups), or 4 groups of 5 and have it split evenly.

If it has dual MPPT controllers, no, as long as you don't exceed the limits they don't need to be balanced in voltage or watts.

Excellent, thanks!
