I have 2- 6500ex48 inverters each is fed from a single 3780w series wired 7 panel string at around 330v. Each string is terminated on Pv 1 of each inverter. Both arrays face true south. I want to add a sw facing group of smaller panels .
3- 30v 250w panels wired in series and tied into pv 2 of one of the inverters is the plan. 90v est.
Will the small array on pv 2 produce power while the voltage on pv1 is so much higher?
 
If they are separate MPPT's, then yes.
If they are 2 inputs to a single MPPT, then I would recommend blocking diodes.
