MPP tracker.
Each PV input operates independently and has its own MPPT. In this way, string
structures of each PV input may differ from each other, including PV module
type, number of PV modules in each string, angle of tilt, and installation
orientation.
Each PV input area includes two DC inputs DC1 and DC2. To make the best
use of PV module input power, string structures of DC1 and DC2 should be the
same, including PV module type, number of PV modules, angle of tilt, and
installation orientation.
