SECTION 8 |
Please refer to wiring layout shown in Fig. 8.1. NOTE: Wiring and Fuse sizes recommended below are based
on use of a single 100W/150W/200W solar panel.
!
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. Please refer to wiring layout at Fig. 8.1 below.
Wiring from Battery to Charge Controller
!
CAUTION!
Wiring and fuse sizing recommended below are provided for up to a single 200W 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 3% at maximum 10A.
•
Use AWG#8 for up to 6' at a maximum current of 30A and 10' at 15A.
•
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 on the battery end of the Positive cable (Fig 8.1; NOT SUPPLIED).
