Fox ESS’s Power Beast platform integrates H3 Plus hybrid inverters with CQ7 high-voltage battery stacks, featuring LFP chemistry, IP65 protection, up to 98.5% inverter efficiency, and more than 95% battery round-trip efficiency. The system supports PV arrays of up to 250 kW, includes three independent battery inputs, and provides EPS backup with transfer times of less than 10 ms.
China-based battery manufacturer Fox ESS has introduced Power Beast, a commercial and industrial (C&I) energy storage solution pairing its H3 Plus three-phase hybrid inverter with the modular CQ7 high-voltage battery architecture.
The company said the new solution is designed to replace complex on-site assembly and extensive cabling requirements with a modular plug-and-play architecture and reduce the number of interconnection steps while helping minimize potential wiring errors during installation.
A key feature is the optional CQ7 Dual Tower Base, which supports two battery stacks from a single base and reduces overall system height by up to 50% compared with conventional single-stack configurations, keeping the installation height below 1.3 meters. The base integrates power and communication channels, enabling rapid stack assembly, with module connections completed in as little as five seconds per unit, according to the manufacturer.
