6.4 Connecting the PV Array (DC)
6.4.1 Conditions for DC Connection
The inverter has two input areas "A" and "B", each with its own MPP tracker. Two strings can be
connected to each of the two input areas.
• For each input area (A or B), the following requirements apply for the PV modules of the
connected strings:
– same type
– same number of in-series-connected PV modules
– identical alignment
– identical tilt
Use of Y adaptors
Y adaptors must not be visible or freely accessible within close proximity of the inverter.
• The DC circuit must not be interrupted by Y adaptors.
• Observe the procedure for disconnecting the inverter from voltage sources
(see Section9.2 "Disconnecting the Inverter from Voltage Sources", page64).
