3.3.2 Connection of the PV-panels
The PV-panel’s DC voltage is connected to the inverter with safe to touch snap con-
nectors in order to provide maximum protection. The inverter is equipped with con-
nectors especially designed for PV-plants from Multi-Contact
®2
.
Make sure the „+“ and „-“ poles of the PV-panel are correctly con-
nected to the respective MultiContact plug connectors at the bottom
of the Sunny Boy.
Depending on the type of PV-panels you must distinguish between connecting one
single or two parallel strings. In order to be able to connect two strings there are two
connectors for plus and minus pole each. The connectors are switched parallel in-
side the inverter.
Seal the unused connectors if you are using only one string.
In order to provide maximum safety during initial installation it is
necessary to have the plus and minus pole from the PV-panels
clearly separated from the PE (protective earth).
