FIGURE 2: Typical Battery Wiring
Note: A typical parallel battery wiring scheme
is depicted here. When wiring batteries in parallel,
it is good practice to attach the (+) and (-) leads to
opposite ends of the battery string, as shown. This
contributes to a more even voltage distribution
among the battery plates when charging and
discharging.
Use only stranded copper wire for DC input/output. Refer to the following chart for the
proper wire size depending on inverter/charger model and the length of wire required*:
Wire Size Chart
Model
12-1200IC
12-1799IC
24-1300IC
*
Meets minimum requirements of ABYC 10% voltage drop table for inverter maximum
input current, 3% voltage drop table for charger maximum output, and allowable
amperage for 105° C rated insulation conductors <50 VDC inside engine space.
Consult ABYC E-9 for lower temperature rated insulated conductors.
CAUTION: Ensure that leads are properly fused no further than 18" from the battery. (Refer
to ABYC recommendations regarding fuse type and location.) Refer to the chart on the fol-
lowing page for the proper battery fuse value for each model:
