User Manual
The inverter SG8K-D has three pairs of PV terminals. The PV1 has an
independent MPP tracker. The PV2 has two pairs of PV terminals, which are
internal paralleled and with one MPP tracker.
The PV1 and PV2 can be configured in independent mode or parallel mode.
For SG8K-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 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 string, tilt angles and orientation angle of PV modules.
