Possible configurations of batteries
If several batteries are used, there are various configuration possibilities of the battery
banks depending on the inverter model (12 V, 24 V, 48 V) .
• Series connection (serial): voltages add up, capacity remains unchanged .
• Parallel connection (parallel): capacities add up, voltage remains unchanged .
• Series and parallel connection (serial and parallel): capacities and voltages add up .
Examples:
+
12 V/200 Ah
12 V + 12 V + 12 V + 12 V = 48 V
+
12 V/200 Ah
Voltage remains at 12 V
+
12 V/200 Ah
+
12 V/200 Ah
Two strings of batteries in series are connected in parallel. The voltage increases to 48 V
and the amp hours increase to 400 Ah
