Fox ESS CQ7-M Master Battery Pack (with BMS, 7.02 kWh)

The base (Master) module of the CQ series high-voltage battery system with a capacity of 7.02 kWh. The key feature of the CQ7-M model is its integrated intelligent Battery Management System (BMS). This module serves as the foundation for building a high-voltage battery stack. It acts as the "brain" of the system, controlling the charge/discharge processes, protecting the cells from overloads, and communicating directly with the inverter.

Advantages:

• Integrated BMS (Master Module): Manages all connected battery units, balances the cells, and ensures the flawless operation of the entire system.

• High-Voltage Technology: Delivers lower transmission losses, faster charging speeds, and better overall efficiency for the solar power station.

• Foundation for Scalability: By purchasing this block, you can easily expand your storage capacity in the future by adding more affordable expansion modules (Slave units without BMS).

• LiFePO₄ Reliability: 100% safe for installation and use in residential areas.

Ideal For:

• Anyone building a modular high-voltage system based on Fox ESS hybrid inverters. This module is the mandatory first element (Master) in the CQ7 series battery stack.
