6.4 PV Connection
Before connecting the PV array to the inverter, ensure that the impedances
between the positive terminals of the PV string and Earth, and between the
negative terminals of the PV string and Earth are larger than 200 kOhm.
6.4.1 PV Input Configuration
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
strings, tilt angles and orientation angles of PV modules. The following figure details
the need for a homogenous PV string structure for maximum power.
Prior to connecting the inverter to PV inputs, the specifications in the following
table should be met:
