WENZHOU, China, Sept. 23, 2026 /PRNewswire/ — Fox ESS, a global leader in renewable energy solutions, has unveiled Power Beast at its 2026 Fox ESS New Product Launch Event on Sept 21, marking a new step for advanced commercial and industrial (C&I) energy storage systems. The first large-scale product launch for Fox ESS in APAC was held in an open-air setting in Wenzhou, with more than 200 customers attending from around the world.
Power Beast is designed as a game-changing C&I energy storage system. It comprises the 125 kW H3 Plus hybrid inverter and the high-voltage CQ series batteries. Notably, the CQ20 stands out as the industry’s first modular C&I energy storage system with a fully integrated hybrid inverter, enabling flexible, all-in-one deployment.
Michael Zhu, CEO of Fox ESS, said: “Today, we are not only launching a product, we are demonstrating our capability as an integrated energy storage provider. Power Beast reflects our commitment to global clients by delivering higher efficiency, lighter weight, and smarter energy management.”
Lyren Liu, CCO of Fox ESS, shared insights on market growth and his perspective on battery storage during the presentation. To help the audience better understand the product, Liu pulled back a black curtain on stage to reveal a Cybertruck filled with CQ batteries. He then invited the installation team to begin a live build, with a timer displayed on the main screen.
As the demonstration started, the team assembled battery packs for 8 modules of CQ20, 12 modules of CQ7 and 12 modules of CQ6, totalling 316 kWh. The complete system was then connected to the charging piles, diesel generator, and motor. The entire live demonstration was successfully completed in under 30 minutes.
Key strengths about Power Beast:
Flexible to scale
Power Beast is built for modular expansion. With one H3 Plus inverter, the system can cover capacities from 28 kWh to nearly 1,000 kWh. It is also suitable for multiple deployment scenarios, including rooftop, outdoor and indoor applications.
In grid-connected mode, Power Beast supports up to 100 units in parallel, delivering a total capacity of up to 96 MWh. In off-grid mode, it supports up to 30 units in parallel, reaching 28.8 MWh.
Simple to deploy
Ease of installation is a core part of Power Beast’s key strengths. Its modular design is intended to improve deployment efficiency and adapt to challenging or irregular environments. The total installation time can be reduced by 90 per cent.
Powerful by design
Power Beast is designed to integrate flexibly with multiple energy sources and loads. The CQ20 series batteries achieve a unit energy weight of 7 kg per kWh, supporting a lighter system footprint while maintaining energy output.
Additionally, safety is addressed through a five-layer end-to-end approach, covering cell-level protection, electrical and structural design, active detection and emergency response.
Smart management
Power Beast connects to FoxCloud 2.0, Fox ESS’s proprietary smart energy management platform. It provides real-time monitoring, scheduling across up to 96 time slots, clear visibility of energy flows and performance analysis, enabling one-stop smart energy management.
Fox ESS also introduced its AI agent, Maimai, to provide detailed product, installation and usage information at any time. Using large-model conversational capabilities, it can understand user needs through natural dialogue and generate optimised energy strategies based on historical consumption patterns and real-time dynamic electricity prices.
“We believe a great product speaks louder than marketing. That is why we aim to make our products the best kind of promotion, by delivering real value every single day,” Michael Zhu said.
