WIRING
The battery must be wired to the charge controller before the solar panel is connected to the charge controller.
A pair of 20 foot pre-assembled cables with Multi-Contact (MC) male and female connectors is provided
primarily to connect the solar panel to the charge controller. After making sure that sufficient length is
available to wire the solar panel to the charge controller, any excess wire maybe used to wire the battery to the
charge controller.
6.1. Battery to Charge Controller
•
Mark the cables to differentiate between Positive and Negative.
•
Make sure the Positive terminal (marked ‘+’) of the battery is connected to the Positive terminal (marked
“BAT +”) of the charge controller and the negative terminal (marked ‘-’) of the battery is connected to
the Negative terminal (marked “BAT -”) of the Charge Controller SCC-30AB. If you are not sure use a DC
voltmeter to determine the polarity of the battery bank.
Reverse polarity connection will damage the
Charge Controller and the resulting damage will not be covered by warranty.
•
Crimp the insulated fork terminals provided (Fig 6.1.3) to one end of the Positive and Negative battery
leads.
•
Insert the fork terminals (fig 6.1.3) into the appropriate terminal on the charge controller: Positive lead is
connected to the Positive terminal (marked “BAT+”) of the charge controller Negative lead is connected
to the Negative terminal (marked “BAT -”) of the Charge Controller SCC-30AB.
•
Crimp the battery ring terminals (fig 6.1.2) provided to the Positive and Negative wire leads to be
connected to the battery terminals.
•
Clean the battery post terminals free of corrosion and other impurities.
•
Bolt the ring terminals to the battery terminals making sure the correct polarity is observed.
6.2. Solar Panel to Charge Controller
1. Determine the position of the solar panel on the RV roof. While positioning panels, avoid shading of the
solar panel by neighbouring obstacles such as vents, air-conditioners, TV antennas etc. As far as possible,
position the panels to minimize wiring distance between the solar panel and the charge controller. Place
the panel at least 8-10 inches away from the RV roof edges and leave sufficient space to walk around the
panel and access the mounting hardware.
2. Make sure the thickness of the roof at the installation location is at least ½” thick and the material
is strong enough to provide mechanical support to the solar panel and mounting hardware against
possible wind loading. Place the panel length-wise to reduce the effects of wind loading on the RV.
