Connecting the DC
Use any of the DC side conduit inputs. Each punch-out opening has two sizes ¾”
and 1”.
1
Connect the DC connectors from the photovoltaic installation to the DC+ and
DC- connectors as shown in Figure 16.
Two strings may be connected in parallel to both DC inputs of the inverter.
They are simply wired together in the terminal block inside.
2
Connect the DC equipment grounding to the equipment grounding terminal
block.
If more than two strings are required, they can be connected in parallel in an
external combiner Box before connecting a unified DC connection to the
inverter.
NOTE:
If more than two strings are connected each should be properly fused on both
DC+ and DC- according to NEC690.35(B).
NOTE:
SolarEdge’s fixed input voltage architecture enables the parallel strings to be
of different lengths. Therefore, they do not necessarily need to be connected
to an identical number of power optimizers.
The lengths of the wires to strip are as follows:
Figure 29: Wire Lengths to Strip – DC
•
Strip 8 mm (0.32'') to enable contact
•
Each cable length is 50 mm (2'')
CAUTION:
Ensure that the + wire is connected to the + terminal connector and that the -
wire is connected to the - terminal connector.
S'assurer que le câble + est connecté à la borne + et que le câble - est
connecté à la borne -.
