6.4.1 PV Input Configuration
Independent Mode
The two 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 strings, tilt angles and orientation angles of PV modules. The
following figure details the need for a homogenous PV string structure for
maximum power.

Parallel Mode
Both PV strings should have the same type, the same number of PV panels,
identical tilt and identical orientation. Two trackers are configured in parallel to
handle power and/or current levels higher than those a single tracker can
handle.
