Traits
  • Scalable
  • Off-Grid Capable
  • Backup Capable
The physical characteristics of a battery help determine whether you’ll need an entire garage of batteries or a wall-mounted, radiator-size battery. Beyond just storing energy, batteries have a number of additional traits, such as being able to easily scale in size or to provide power if the grid goes down.
