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 C-4 and Figure C-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.
