FOX ESS EQ4800-S – 4.66kWh Battery Module Slave
The FOX ESS EQ4800-S is the secondary (slave) battery module designed for use within the FOX ESS EQ Series high-voltage energy storage system. Engineered to expand system capacity while maintaining exceptional performance, safety, and reliability, the EQ4800-S allows homeowners and businesses to scale their energy storage solution according to their evolving energy requirements.
As part of the modular EQ Series architecture, the EQ4800-S works alongside the EQ4800-M Master (Leader) module to create a flexible, high-voltage battery storage system. Additional slave modules can be connected in series, enabling storage capacities of up to 41.94kWh in a single stack configuration when combined with one master module and up to eight slave modules.*
Designed for seamless integration with solar energy systems, the EQ4800-S is fully compatible with the complete range of FOX ESS single-phase and three-phase Hybrid and AC-coupled inverters. The high-voltage design delivers efficient energy transfer, improved system performance, and optimized charging and discharging capabilities.
Installation is fast and straightforward thanks to the plug-and-play modular design, reducing installation time and simplifying system expansion. Built with advanced lithium battery technology and protected by an intelligent Battery Management System (BMS) managed through the master module, the EQ Series delivers dependable long-term performance with a 12-year warranty and robust environmental protection.
With an IP65-rated enclosure, the EQ4800-S is suitable for both indoor and outdoor installations, offering reliable operation in a wide range of environmental conditions.
