FOX ESS CQ6-S – 5.99kWh Battery Module Slave
The FOX ESS CQ6-S is the slave (expansion) battery module designed for the FOX ESS CQ6 high-voltage residential energy storage system. Built with advanced Lithium Iron Phosphate (LFP) battery technology, the CQ6-S provides 5.99kWh of usable energy storage and enables homeowners to expand their battery capacity as energy demands grow.
Operating as part of a modular high-voltage battery platform, the CQ6-S must be connected to a FOX ESS CQ6-M Master Module, which manages system communication, monitoring, and battery protection. Additional slave modules can be integrated into the same battery stack, creating a scalable energy storage solution tailored to residential solar installations and energy independence goals.
The CQ6 Series is designed for DC-coupled applications and must be paired with a compatible FOX ESS hybrid inverter. The system integrates seamlessly with the latest FOX ESS single-phase and three-phase hybrid inverter ranges, supporting efficient solar energy storage, enhanced self-consumption, and reduced reliance on grid electricity.
With 100% Depth of Discharge (DoD), the CQ6-S allows users to access the full available battery capacity, maximizing energy utilization and system value. The battery features a robust IP65-rated enclosure, making it suitable for both indoor and outdoor installations, while fan-free natural convection cooling ensures silent operation, increased reliability, and reduced maintenance requirements.
The modular architecture also allows future system expansion when required, offering flexibility for homeowners seeking a long-term energy storage solution. Expansion modules must meet FOX ESS voltage and commissioning requirements to maintain warranty compliance and ensure optimal system performance.
