The Energy Stack

Store energy safely and affordably with our new silicate-salt battery storage system.

View Details

The Energy Stack is a residential energy storage system (ESS) that includes a modular silicate-salt rechargeable battery system.  

Our world patented battery electrolyte allows consumers to power their homes longer during grid outages without damaging the batteries.  

The Energy Stack is compatible with standard inverters and charge controllers and can be charged and discharged quickly without producing heat.  

The Energy Stack is available in a range of capacities from 5.2 kW and up. Consumers can add as many levels necessary to meet their energy storage needs.

  • Holds charge for long periods of time without needing recharging
  • Modular design allows expansion of 24V or 48V stackable modules
  • Energy storage for any environment, no ventilation or cooling necessary
  • Stackable for increased energy storage demands (5.2 kW and up)
  • No thermal runaway risk, non-explosive, compatible with industry standard inverters and charge controllers
  • Powers home in emergencies (off-grid capable)
  • 100% discharge capable
  • No risk of thermal runaway
  • Batteries are completely sealed, requiring no maintenance
  • Batteries are non-corrosive, non-explosive, and fast charge capable
  • Performs in extreme high and low temperatures
  • Non-toxic and non-hazardous recyclable materials
