For SH5/6/8T, 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.

For SH10/12T, each pair of PV terminals is corresponding to an independent PV string. PV

input PV1, PV2 connect to MPPT1 and PV3 connect to MPPT2. For the best use of PV

power, PV1 and PV2 should be the same in PV string structure, including the type, number,

tilt, and orientation of the PV modules.

For SH15T, each pair of PV terminals is corresponding to an independent PV string. PV in-

put PV1, PV2 connect to MPPT1, PV3 connect to MPPT2 and PV4 connect to MPPT3. For

the best use of PV power, PV1 and PV2 should be the same in PV string structure, including

the type, number, tilt, and orientation of the PV modules.

For SH20/25T, each pair of PV terminals is corresponding to an independent PV string. PV

input PV1, PV2 connect to MPPT1, PV3, PV4 connect to MPPT2 and PV5 connect to

MPPT3. For the best use of PV power, PV1 and PV2, PV3 and PV4 should be the same in

PV string structure, including the type, number, tilt, and orientation of the PV modules.
