Wiring Batteries in Series-Parallel
Effect
Wiring the batteries in a series-parallel configuration increases the current and
voltage of the battery bank. “Series-parallel” wiring is more complicated and care
should be taken when wiring these banks.
Steps
It is done in three steps; wiring the batteries in series, wiring them in parallel, then
wiring the string to the inverter.
Series wiring
To wire in series:
1. First wire the batteries in “series” (voltage adds) with the positive terminal of
one battery connected to the negative terminal of the next battery to meet the
inverter’s DC input requirements (24 volts shown in Figure B-4 and Figure
B-5.)
2. Repeat this step for the next battery string.
Two identical strings of batteries are now wired in series.
Parallel wiring
To wire the batteries in parallel:
1. Connect the positive terminal of the first battery string to the positive terminal
of the second battery string.
2. Connect the negative terminal of the first battery string to the negative
terminal of the second battery string.
