Hi. I am working with an inverter for solar pv that has two MPPTs but each MPPT can accept two strings. Through reading I have done the two inputs to each MPPT essentially lead to a busbar and are combined prior to being tracked and therefore I am unsure as to what the main reason for putting more than one input per MPPT is??
If anyone can shed some light it would be great.
