Battery Wiring Examples
In renewable energy systems, batteries are connected to each other in one of three ways:
-
12V/200 Amp-Hours
12 V + 12 V + 12 V + 12 V = 48 V
-
12 V
200 Amp-Hours
Voltage remains at 12V
-
12V/200 Amp-Hours
-
12V/200 Amp-Hours
Two strings of batteries in series are connected in parallel. The voltage increases to 48V and the
amp-hours increase to 400.
