Comment on Biwatt releases 4.5 kWh sodium-ion battery - Energy Storage

  In the batteries because I thought hooking them up in parallel increases the storage indefinitely without increasing voltage.

    Well in these stacks you usually have a single BMS and each battery is in series. So four units maximum is about 200-240 V and not exeeding that probably makes it simpler to build an inverter for a 240V regular house grid.

      But my question is why only four stacks in parallel?

      Why can’t you do eight in parallel because you’re only increasing storage but keeping the voltage the same.

      If you read the rest of the thread you’ll see why I’m asking the questions here.

        This I don’t know, but probably some limitation with the control software or some similar issue.
