Tesla launches integrated 20MWh Megapack
Tesla announced its new integrated 20MWh battery energy storage system (BESS) solution, the Tesla Megablock, on 8 September in Las Vegas, US.
The Qianyuan Smart Storage 20MWh system marked its first external exhibition debut at SNEC 2025, where a product launch event and certification ceremony were held. Adopting a modular integration design, the system achieves a single-container capacity of 20MWh and a design lifespan of 25 years, leading the global industry.
The latest generation product has an energy density of more than 440 Wh/l, a roundtrip efficinecy of 96%, and a cycle lifetime of nearly 16,000 charge-discharge cycles. The liquid-cooled system has a voltage range from 1500 V – 2000 V and is configurable for storage durations of two to eight hours. The container weighs around 55 tons.
It managed to achieve the latest breakthrough in capacity due to a combination of factors, primarily its large capacity cells, but also system integration, compact design, and further optimization within the container. In addition to cells, Envision manufactures its own inverters, battery management systems, and energy management systems.
At the EESA show, the company also launched its AI-powered “energy storage + X” solution for grid-scale battery storage systems capable of facilitating sizing and construction of projects as well as their operation, specifically their lifecycle services and trading in the electricity spot market.
