Overview
Megapack arrives pre-assembled — battery, inverter, and thermal management in one enclosure — so a utility-scale storage site that once took years to build now goes from delivery to grid-connected in weeks. Fleets of them firm up solar and wind output and keep regional grids stable through demand spikes.
What sets it apart
Pre-assembled at the factory
Battery, inverter, and thermal system ship as one enclosure, cutting site build time from years to weeks.
Built-in fire suppression
Each unit isolates and manages thermal events on its own, without taking the rest of the site offline.
