The PV1 and PV2 can be configured in independent mode or parallel mode.
For SG8K3-D, the PV strings to PV2 input should have the same PV
module type, the same string length, identical tilt and identical
orientation.

Independent Mode
The PV inputs work independently, each with its own MPPT. The two PV inputs
can be different from each other in PV module types, numbers of PV panels in
PV string, tilt angles and orientation angle of PV modules.
