The Fox ESS CQ7 Master Battery Unit is the central control component of the CQ7 high voltage energy storage system. This is the required master unit that manages and communicates with all connected slave battery modules. It is not optional and must be installed for the system to operate.

Designed for commercial, hybrid, and off-grid solar applications, this high voltage lithium battery master unit handles system coordination, battery management, and inverter communication. It enables scalable energy storage up to 98kWh by controlling multiple slave modules while ensuring safe, balanced, and optimized performance across the entire system.

Whether you are building a full battery energy storage system (BESS) or expanding an existing setup, the CQ7 Master provides the intelligence, protection, and integration backbone required for reliable solar storage.
