Fox ESS CQ7 High-Voltage Battery Storage System
The Fox ESS CQ7 is a powerful, scalable high-voltage battery storage solution designed for residential and commercial energy storage applications. Based on safe and reliable LiFePO₄ (LFP) battery technology, the CQ7 combines high efficiency, flexible expansion options, and easy plug-and-play installation to maximise self-consumption and energy independence.
With a starting capacity of 14.04 kWh, the modular system can be expanded by connecting up to 14 modules in series to reach up to 98.28 kWh, making it suitable for a wide range of project sizes and future energy demands. The system offers a depth of discharge (DoD) of 90% and a round-trip efficiency of over 95%, ensuring maximum usable energy and excellent performance.
Designed for both indoor and outdoor use, the CQ7 features an IP65-rated enclosure, natural convection cooling, integrated fire protection functionality, and CAN communication for seamless integration into compatible energy management systems. The wide operating temperature range and optional battery heating function ensure reliable performance even under demanding conditions.
