Connecting the solar modules (DC)

5.7.2 Separately connected DC inputs

PV array
The module strings are connected directly to the DC inputs DC1
and DC2. MPP tracker 1 regulates the module strings at DC1,
MPP tracker 2 regulates the module strings at DC2.
Both symmetrically and asymmetrically configured DC inputs can
be implemented by connecting the DC inputs separately.
This DC cabling variant must not be used with grounded solar
modules.
