Appendix B - Battery Information
Parallel Wiring
Wiring the batteries in parallel increases the total run time the batter-
ies can operate the AC loads. A parallel connection combines overall
battery capacity by the number of batteries in the string. Even though
there are multiple batteries, the voltage remains the same. In the ex-
ample below (Figure 15), four 12 VDC/100 AHr batteries are combined
into a single 12 VDC/400 AHr battery bank.
Series-Parallel Wiring
A series-parallel con
fi
guration increases both voltage (to match the
inverter’s DC requirements) and capacity (to increase run time for
operating the loads) using smaller, lower-voltage batteries. In the ex-
ample below (Figure 16), four 6 VDC/200 AHr batteries are combined
into two strings resulting in a 12 VDC/400 AHr battery bank.
