What could go wrong?

Product Discussion BLUETTI AC Series

What would happen if you connect two ac300 head units to a single b300 battery/ bank of batteries

theories:

  1. units are smart enough to know something is wrong and error out so you can undo things.
  2. catastrophic damage
  3. nothing - both units try to balance/control the battery bank

@bluetti_zoomzoom The AC300 will report a BMS communication fault (fault code appears). It cannot be used normally, but there will also be no “catastrophic damage”.
