MC4 Power Cabels For Solar Flex
TM
Kits
The MC4 power cable is usually the nal connection between the solar array and
the solar controller. If it has not already been done, cut the MC power cable into
two pieces so that there is a positive conductor cable and negative conductor
cable.
1. Cover the solar module(s) with an opaque material. Attach the appropriate
MC4 power cable conductor to the positive and negative connectors of the
MC4 junction box. If you have more than one module, refer to the specic
diagram for wiring a parallel MC4 connection.
2. Run the positive and negative MC4 cable conductors from the solar array to
the solar controller. Attach a positive polarity label to the end of the positive
conductor. If the positive conductor needs to be shortened and the polarity
label is removed, remember to re-label it as both positive and negative
conductors look exactly the same. Leave a few feet of cable at the solar
controller in case of future adjustment.
Note:
Solar module junction box and MC4 cables many not be exactly as shown.
