Megapack

Grid-scale storage that keeps the lights on.

A fully integrated battery system for utilities and businesses. Store energy when it's abundant, deliver it when it's needed, and stabilize the grid at the scale of a city.

design life

Built to deploy fast and run for decades.

Factory-integrated

Battery modules, inverters, and thermal systems ship as one unit, so sites go from delivery to grid-connected in a fraction of the time.

Software that pays for itself

Built-in software forecasts demand and trades energy automatically, turning stored electricity into revenue.

Safe by design

Each unit is engineered with layered protection and thermal isolation to contain faults and keep operating.

Instant response

Delivers power in milliseconds to smooth spikes, hold frequency, and back up the grid when generation drops.

Scales to the grid

Cluster hundreds of units into gigawatt-hour sites that replace peaker plants and firm up renewables.

Low maintenance

Sealed, weatherproof enclosures and remote monitoring keep on-site work to a minimum.

Where it's used

Utilities

Replace fossil peaker plants, defer transmission upgrades, and firm up wind and solar.

Businesses

Cut demand charges, add backup for critical operations, and hedge against volatile energy prices.

Developers

Pair storage with new solar and wind projects to deliver power on a schedule, day or night.
