WIRING

Typical wiring using a single 150W/100W panel to charge 12V battery is considered and shown in Fig. 8.1.
Minimum recommended Charge Controller capacity is as follows: Single 100W Panel – 8 Amps; Single 150W
Panel – 10 Amps. NOTE: Wiring and Fuse sizes recommended below are based on use of a single 100/150W
solar panel with maximum current handling capacity of 10A.
Caution!
1. The battery must be wired to the Charge Controller before the solar panel is
connected to the Charge Controller.
2. Use appropriate size of fuse in battery Positive Cable to protect against fire hazard
due to short circuit in the battery cables.
A pair of 20 foot, AWG#12, pre-assembled cables with Multi-Contact (MC4) Male and Female Connectors
is provided 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 may be used to wire the battery to
the Charge Controller. Please refer to wiring layout at Fig. 8.1 below.
Wiring from Battery to Charge Controller
• Use AWG#12 for up to 6 ft. and AWG#10 for up to 10 ft. to limit voltage drop to 2% at maximum 10A.
• 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 (Fig. 8.1). If you are not sure, use a DC
voltmeter to determine the polarity of the battery bank. Reverse polarity connection may damage the
Charge Controller and the resulting damage will not be covered by warranty.
• 2 pieces of Ring Terminals (Fig 8.2) have been provided for crimping on the wire ends on the
battery side.
• Use Inline ATC style Fuse Holder of 10A ATC-10 fuse on the battery end of the Positive cable (Fig 8.1; NOT
SUPPLIED). The Fuse Holder comes with 4", AWG#12 pigtails. Splice one pigtail to the Positive wire end
and use the other pigtail for battery connection.
Warning:
Be careful not to short the battery
