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.

12 V + 12 V + 12 V + 12 V = 48 V Amp Hours remain at 200
Voltage remains at 12 V
Two strings of batteries in series are connected in parallel. The voltage increases to 48 V
and the amp hours increase to 400 Ah
200 Ah + 200 Ah + 200 Ah + 200 Ah = 800 Ah
