• The Positive (+) wire of the solar panel is terminated with a MC4 female Connector (). Connect
this to the MC4 Male Connector (marked -) that is attached to the Positive PV extension Wire. Make sure
that the locking tabs “snap in” for a firm connection. The bare end of the Positive extension Wire will
now be of Positive polarity. Use a piece of red sleeve or red tape near the bare end for identification as
the Positive (+) wire.
• The Negative (-) wire of the solar panel is terminated with a MC4 Male Connector (marked -). Connect this to
the MC4 female Connector () that is attached to the Negative extension wire. Make sure that the
locking tabs “snap in” for a firm connection. The bare end of the Negative PV extension Wire will now be of
Negative polarity.
• Connect the two PV extension Wires to the Charge Controller.

ensure that the polarity (+ or -) of the wires is identified correctly before connecting to the Charge
Controller. Damage due to wrong polarity may not be covered under warranty.
