Why LiFePO4?
Lithium Iron Phosphate (LiFePO4) is the safest lithium battery chemistry — non-flammable, thermally stable, and rated for 6,000+ cycles. Unlike NMC batteries (used by some competitors), LiFePO4 cells do not undergo thermal runaway, making them safe for indoor installation.
What It Stores and Powers
16 kWh is enough to power essential home loads — refrigerator, lighting, router, TV, phone charging, and fans — for 24–36 hours. Paired with an EcoPowerWall inverter and solar panels, it stores excess solar energy for nighttime use and grid-outage backup.
Perfect For
- 2–4 bedroom homes with average daily energy use under 30 kWh
- Daily solar storage and time-of-use rate optimization
- Essential load backup during outages (24–36 hrs)
- Entry-level whole-home energy storage with upgrade path
