Commercial Battery Storage from 2.5MWh to 10MWh+

TESLA Megapack

Tesla Megapack
Fully Integrated System

Tesla Megapack Complete energy storage systems including DC batteries, bi-directional inverters, and site controllers with intelligent software and up to a 20-year warranty. These turnkey systems are designed to minimize installation costs and maximize commercial solar project savings at scale. 

The future of renewable energy relies on large-scale energy storage. Megapack is a powerful commercial solar battery that provides energy storage and support, helping to stabilise the grid and prevent outages. By strengthening our sustainable energy infrastructure, we can create a cleaner grid that protects our communities and the environment.

Tesla Megapack
Intelligent Software

Tesla Megapack systems come with the most advanced autonomous control software available to ensure customers maximize economic benefits. Megapack software learns and predicts energy patterns, optimizes battery dispatch to reduce electricity bills, increases consumption of on-site solar, and enables various grid services.

Megapack stores energy for the grid reliably and safely, eliminating the need for gas peaker plants and helping to avoid outages. Each unit can store over 3 MWh of energy—that’s enough energy to power an average of 3,600 homes for one hour.

Tesla Megapack
Enhanced System Safety

Through vertical integration, Tesla Megapack is designed and manufactured with safety built directly into the product. Megapack systems include an integrated liquid cooling and heating system for thermal safety as well as enhanced reliability and performance.

Megapack delivers more power and reliability at a lower cost over its lifetime. Each battery module is paired with its own inverter for improved efficiency and increased safety. With over-the-air software updates, Megapack gets better over time.

Megapack is one of the safest commercial solar battery storage products of its kind. Units undergo extensive fire testing and include integrated safety systems, specialised monitoring software and 24/7 support.
