The module strings for DC1 and DC2 are connected sepa-
rately. MPP tracker 1 regulates the module strings at DC1, MPP
tracker 2 regulates the module strings at DC2.
This allows implementation of symmetric and asymmetric config-
urations at the DC inputs.
This DC cabling variant cannot be used with grounded solar
modules.
