Fig. 6.12: I-V characteristics for symmetric and asymmetric

configuration of the DC inputs (illustration of princi-

ple)

For currents and voltages, refer to “14. Technical

data”, page 162.

6.8.2 Separate and parallel connected DC inputs

The inverter can be used with separately or parallel connected

DC inputs.

Separately connected DC inputs

DC wiring

PV array

Fig. 6.13: Separately connected DC inputs

In this case the module strings for DC 1 are connected sepa-

rately from those for DC 2. MPP tracker 1 controls the module

strings on DC 1 and MPP tracker 2 controls the module strings

on DC 2.
This way, symmetrically and asymmetrically configured DC inputs

can be implemented.
This variant of the DC cabling

cannot

be used for solar modules

that are grounded.
