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.
Certifications Received
None
Organizations like the International Electrotechnical Commission (IEC) and Underwriters Laboratories (UL) create national and international standards for energy storage systems to ensure any products on the market meet certain specifications for safety and reliability reasons.
