Can anyone tell me why PV is considered an excellent battery charger? I
think it is, only after the addition of a MPPT charge control.  Otherwise,
the battery drags the PV voltage below Vmp.

One of the NABCEP objectives for the entry level class is to explain why
PV modules make excellent battery chargers and show this through the IV
curve.

Thank you,

Drake
