Sunny Boy 700
Connection to the PV-modules
In order to simplify safe mounting and servicing the Sunny Boy is connected to the
PV-modules with safe to touch snap cable connectors type Multi-Contact which were
especially designed for PV applications.
Make sure that the + and – snap cable connectors of the PV-modules
are connected to the right poles of the PV module voltage.
Depending on the type of PV-module used it is possible to connect one single string
or two parallel strings. Therefore there are two connections for both the + and the –
pole. Within the device these connections are connected in parallel each.
Should you be working with one single string connection please
close the unused plug-in contacts on the Sunny Boy by the seals
provided with the delivery.
Before connecting the snap cable connectors of the PV-panel to the
Sunny Boy check the correct polarity and admissible PV-panel volt-
age between the + and the – snap cable connector of the PV-panel.
The PV-panel voltage must be below or at most equal 250 V DC
≤ 250 V DC).
