🏡 Residential & Off-Grid Power

Quiet. Safe. Always On.

Backyard Energy brings industrial-grade reliability to homes, cabins, and off-grid life—without the fire risk, degradation, or complexity of traditional batteries.

🔋 Simple Storage for Remote Living

Whether you’re living off the grid, building a homestead, or preparing for outages, our flywheel systems deliver instant, long-life backup power that’s:

• 🔥 Non-flammable (no lithium, no thermal runaway)
  
  

• 💨 Instant-on (sub-second switchover)
  
  

• ♻️ Maintenance-free and recyclable
  
  

• 🌞 Compatible with solar, wind, and generators
  
  

🧘‍♂️ Peace of Mind, Not Just Power

Our system doesn’t need HVAC, doesn't off-gas, and doesn’t decay when left idle. It’s:

• Silent, sealed, and built to run for decades
  
  

• Ideal for basements, garages, sheds, and outbuildings
  
  

• Immune to temperature swings and rough terrain
  
  

⚡ Built for Where the Grid Doesn’t Go

Perfect for:

• Off-grid cabins and homesteads
  
  

• Remote tribal communities
  
  

• Fire-prone regions where batteries aren’t an option
  
  

• Outage-prone homes needing backup (no noise, no fuel)
  
  

• Solar-first homes looking to shift use to evening or backup loads
