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)

SERIES (EXAMPLE)

-	-
12 V/200 amp-hours	12 V/200 amp-hours

12 V + 12 V + 12 V + 12 V = 48 V

-	-
12 V/200 amp-hours	12 V/200 amp-hours

Amp-hours remain at 200

PARALLEL (EXAMPLE)

-
		-	-		-
12 V/200 amp-hours		12 V/200 amp-hours	12 V/200 amp-hours		12 V/200 amp-hours
	Voltage remains at 12 V			200 Ah + 200 Ah + 200 Ah + 200 Ah = 800 Ah

SERIES/PARALLEL (EXAMPLE)

-	-	-	-
12 V/200 amp-hours	12 V/200 amp-hours	12 V/200 amp-hours	12 V/200 amp-hours
-	-	-	-
12 V/200 amp-hours	12 V/200 amp-hours	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.
