Giga-Scale Projects

We took everything we know about battery technology to enable the world's largest energy projects. A 1 Gigawatt hour (GWh) project provides record energy capacity—enough to power every home in San Francisco for 6 hours.

All-in-One System

Every Megapack arrives pre-assembled and pre-tested in one enclosure from our Gigafactory—including battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls. No assembly is required, all you need to do is connect Megapack’s AC output to your site wiring.

Fastest Installation

At the site level, Megapack requires 40% less space and 10x fewer parts than current systems on the market. As a result, this high-density, modular system can be installed 10x faster than current systems.


  • Renewable Smoothing

    Smooth out the intermittency of renewables by storing and dispatching when needed
