5.4 PV generator connection (DC)
5.4.1 Conditions for the DC Connection
• Requirements for the PV modules of the connected strings:
– Same type
– Same number
– Identical alignment
– Identical tilt
• The connecting cables from the PV modules must be fitted with plug connectors. You will find
the necessary DC plug connector for DC connection in the delivery.
• The following limiting values at the DC input of the inverter may not be exceeded:
Use of Adaptors
Adaptors (branch connectors) must not be visible or freely accessible in the immediate
surroundings of the inverter.
• The DC current flow may not be interrupted via adaptors.
• Observe the procedure for disconnecting the inverter as described in section
7.2 ”Opening the Inverter” (page 45).
Inverter Maximum input voltage Maximum input current
SB 1200 400 V (DC) 12.6 A (DC)
SB 1700 400 V (DC) 12.6 A (DC)
DANGER!
Risk of lethal electric shock or fire.
The maximum possible input current per string is limited by the plug connectors used. If the
plug connector is overloaded, an electric arc may occur and there is a fire risk.
• Ensure that the input current for each string does not exceed the maximum flow
current of the plug connectors used.
