Please refer to wiring layout shown in fig. 8.1. 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
!
CAUtion!
Wiring and fuse sizing recommended below are suitable for up to 150W panel only. If additional
panels are added in parallel to increase capacity, wiring and fuse sizes will be required to be
changed accordingly.
• 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 SCC-30Ab (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.
• 4 pieces of fork Terminals (fig 8.3) have been supplied for crimping on to the wire ends on the
Controller side.
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.
