SECTION 3 |
A second solar panel can be connected in parallel with the panel provided in the kit to increase the current
output at the same output voltage. Fig. 3.4 above shows the arrangement for connecting the second solar
panel in parallel using the Solar Panel Connecting Wire Kit Model SCW-20-2 supplied with this kit, and MC4
Branch Connector Kit (SBC-2), sold separately. This arrangement is applicable if the two solar panels are to
be connected in parallel and are mounted adjacent to each other.
The output wires of the two solar panels are first connected in parallel using the MC4 Male and Female
Branch Connectors. The outputs of the Branch Connectors are then connected to the SCW-20-2 wires for
connecting to the external PV circuit.
Connecting Second Solar Panel in Parallel When Separated by a Distance (Fig. 3.5)
Fig. 3.5. Connecting two solar panels in parallel that are separated by an extended distance
Fig. 3.5 above shows an arrangement for connecting second solar panel in parallel that is separated by an
extended distance. In this case, the following will be required:
• SCW-20-2 Connecting Wires Kit - 2 sets (one set is provided with this kit. Second set has to be ordered
separately)
• One MC4 Male Branch Connector and one MC4 Female Branch Connector sold separately as an optional
kit – Model No. "SBC-2" Kit
• One MC4 Male Connector and one MC4 Female Connector sold separately as an optional kit – Model
No. "MC4-2"
In this case, one Connecting Wire Kit "SWC-20-2" and the optional MC-4 Connectors Kit "MC4-2" are first
used to bridge the extended distance between the panels. The optional Branch Connector "SBC-2" Kit is
used to parallel the two solar panels. The second Connecting Wire Kit "SWC-20-2" is used to connect to the
external PV circuit.
