BATTERY WIRING

In DC systems, batteries are connected to each other in one of three ways:
• Series (voltage increases, amperage stays the same as a single battery)
• Parallel (voltage stays the same as a single battery, amperage increases)
• Series/Parallel (both voltage and amperage increase)
-
12 V/200 amp-hours
12 V + 12 V + 12 V + 12 V = 48 V
-
12 V/200 amp-hours
Voltage remains at 12 V
-
12 V/200 amp-hours
-
12 V/200 amp-hours
Two strings of batteries in series are connected in parallel. The voltage increases to 48 V and
the amp-hours increase to 400.
Since the OBX-IC2024S-120/60 is a 24-volt inverter, any series or parallel battery connections must be made
for a 24-volt system. Methods for doing this will vary with battery type. Some examples are shown on the
following pages.
