Connecting the solar system
The solar system connections are made using MC4
connector plugs and sockets. The string inverter is equipped
for 2 photovoltaic strings. If you want to connect more
photovoltaic strings, use
Multi-Contact
branch connector
plugs and sockets. Note the specifications of the string
inverter.
The MC4 connector plugs and sockets are intended for a
cable section of 4 to 6 mm
2
and an average cable section of
5.5 to 9 mm. To connect the solar system to the inverter you
can use pre-assembled cables or crimp the cables to the
connector plugs and sockets.
If you use pre-assembled cables, you can by-pass the next
stage and connect the cables directly to the string inverter
plugs and sockets (see Fig. 6-12, page 44).
