ALF HomeVault Na Series — Sodium-Ion home energy storage system

Inherent Safety

01 — Zero Thermal Runaway Risk

Inherently Stable.
Total Peace of Mind.

Powered by ALIFE AIR's proprietary Sodium-Ion 18650 architecture, HomeVault™ eliminates the thermal runaway risks inherent in conventional lithium storage systems. Deploy with complete confidence inside your home, garage, or utility room — with no toxic gas or fire risk under any charge state.

Lithium-free — zero thermal runaway risk at the cell level
Safe for indoor, garage, and enclosed space installation
Electrochemically stable across all charge states

HomeVault Na Series — reliable performance in extreme climates

Climate Resilient

02 — Built for Real-World Conditions

Any Climate.
Consistent Performance.

Operating reliably from -20°C to 55°C, Sodium-Ion chemistry maintains full rated performance where other chemistries degrade. Whether during peak summer demand or a winter power outage, your home remains powered without compromise or cold-weather derating.

Full-rated performance across -20°C to 55°C
No cold-weather derating or thermal throttling
Engineered for tropical, arid, and sub-zero climates

ALF HomeVault Na Series — long-life modular residential energy storage

Deployment Scenarios

Built for Every
Home Energy Scenario

From solar self-consumption to full off-grid living, HomeVault™ delivers the flexibility and reliability to meet every residential energy challenge.

Solar Self-Consumption

Store excess solar generation and discharge during peak evening demand to maximise self-consumption and eliminate grid dependency.

Backup Power

Seamless whole-home backup during grid outages, keeping essential loads powered with silent, zero-emission Sodium-Ion energy.

Off-Grid Living

Full energy independence for remote properties, rural homesteads, and eco-communities where grid connection is impractical or undesirable.

EV Home Charging

Battery-buffered home EV charging eliminates demand charges and enables overnight solar-charged top-ups without peak tariff exposure.

Time-of-Use Optimisation

Charge during low-tariff off-peak periods and discharge during expensive peak windows to systematically reduce household energy bills.

Generator Replacement

Replace diesel or petrol generator backup with clean, maintenance-free Sodium-Ion storage — quieter, safer, and more cost-effective long term.
