OES2™ Brand


The OES2™ utilizes Ojai Energy System's Lithium Ferrous Phosphate (LFP) technology in a unique, scalable, intelligent, high-density energy storage product designed specifically for:

  • Solar and wind generated energy
  • On-grid and Off-grid storage scenarios
  • Integration with all forms of electricity generation

The key to the OES2™ is its modular scalability, compact form, safety and long life.

Benefits of the OES2™:

  • No ventilation needed, no off gassing
  • Safe and reliable, no maintenance
  • Thermal stability
  • Offers surge protection
  • Small footprint, modular, scalable system
  • Moisture and corrosion resistant
  • Projected 20+ year life
  • Recyclable, non-hazardous, environmentally benign in its manufacture and disposal per US government
  • RoHS compliant
  • 10-year or 2500-cycle warranty


  • The OES2™ is designed to be essentially maintenance-free over the long life of the unit
  • Remote monitoring options


  • Negligible self discharge over extended periods
  • Negligible internal heat gain
  • No off gassing
  • 90 percent depth of discharge
  • Up to eight times cycle life of other battery types
  • Fast charging capabilities

OES2™ benefits for residential systems:

  • Store excess renewable power for off-peak use or resale
  • Reduce energy costs, extend life of appliances and motors
  • Have back-up and emergency power during grid power failures or maintenance of renewable power sources

Designing the OES2™ system:

  • OES2™ units can be specifically designed to be compatible with varying voltage, current, size and weight applications
  • OES2™ units can be equipped with intelligent energy management circuitry that monitors and controls high and low voltage, temperature and short circuits. The system can continuously monitor cell life and even distribution of energy across the cells
  • Residential and small commercial systems can be sized from 1 kWh – 250 kWh
  • System can be designed for 12, 24, and 48 Volt systems.


Warranty and Manual:

OES1™ and OES2™ products are warranted to be free from defects in material and workmanship for a period of ten (10) years from the date of shipment or 2500 cycles, whichever first occurs.  This warranty is solely for the benefit of the original end use. Dependent upon application.
