Flywheel, battery, inverter/controller, enclosure, and internal sensors.
Turn-key install
$42k–$49k
Typical full system with professional installation, commissioning, and permitting.
Everyday coverage
24 kWh/day
Sized for a two-bedroom residence with room for surge loads and peak events.
Engineered for resilience
- Flywheel absorbs instant surges and heavy startup loads.
- 16 kWh LFP pack keeps essential circuits powered for hours.
- Redundant architecture eliminates single-point failures.
- Ready for solar, EV charging, and microgrid integrations.
Hardware price only.
Base pricing covers the flywheel module, battery pack, inverter/controller, safety enclosure, and sensor suite.
Professional installation, site preparation, commissioning, and permitting are quoted separately to ensure compliance
and full warranty support.
System overview
Why hybrid? Energy is stored as rotational power inside a high-speed flywheel for instantaneous
response and within advanced lithium batteries for long-duration supply.
Result: Whole-home coverage that handles daily consumption, peak surges, and outage protection with
no single point of failure.
- Grid backup, smoothing, and peak shaving.
- Confidently starts HVAC compressors, pumps, and other high-surge loads.
- Designed for garages, basements, or dedicated energy rooms.

Main advantages
Rapid surge response
Flywheel instantly covers motor and compressor startup loads so the battery experiences minimal stress.
Long-duration backup
The lithium pack provides overnight or multi-hour coverage, maintaining critical circuits through grid outages.
Built-in resilience
Dual storage paths, safety braking, and real-time monitoring safeguard against battery or grid faults.
Scale your system.
Upgrade to composite flywheels, add modular battery packs, or scale output beyond 50 kWh for estates, commercial sites, or microgrids. Custom three-phase and remote-ready builds are available.
