Fox ESS CQ7-M-50 7.02kWh HV LiFePO4 Master Battery Module – Module Only

The Fox ESS CQ7-M-50 is the Master battery module for the Fox ESS CQ7 high-voltage battery storage system. This module combines a 7.02kWh LiFePO4 battery module with the system controller required to manage the complete CQ7 battery tower. Each Fox ESS CQ7 system requires one CQ7-M-50 Master module, combined with one or more compatible CQ7-S-50 Slave battery modules.

With a nominal energy capacity of 7.02kWh, a nominal voltage of 57.6V and a nominal capacity of 122Ah, the CQ7-M-50 provides the foundation for a scalable and reliable high-voltage energy storage system. The battery uses safe and durable Lithium Iron Phosphate technology, offering stable performance, long service life and excellent operational safety.

This product is supplied as one Master battery module only. It does not include Slave battery modules or a complete battery tower. For a working CQ7 battery system, the Master module must be combined with at least one CQ7-S-50 Slave module. The CQ7 system can be expanded up to 98.28kWh, making it suitable for both residential and commercial energy storage applications.

The CQ7-M-50 is designed for easy installation and flexible system expansion. Its modular design allows additional battery modules to be installed in series, while CAN communication ensures efficient interaction with compatible Fox ESS hybrid inverters. With IP65 protection, natural convection cooling and indoor/outdoor stand installation, the CQ7-M-50 is built for dependable performance in a wide range of installation environments.

The Master module features a 50A maximum charge/discharge current, 65A peak discharge current for 60 seconds, a wide operating temperature range and a robust housing with compact dimensions of 660 × 360 × 205mm. With an approximate weight of 55kg, it is designed as a solid and reliable base component for a professional Fox ESS CQ7 high-voltage battery system.

The Fox ESS CQ7 series also includes multiple protection functions and an integrated fire protection function, supporting safe and reliable energy storage operation. The CQ7-M-50 is the correct choice when building a new Fox ESS CQ7 battery tower or replacing/adding the required Master module in a compatible CQ7-50 system.

Important: This product is the Master battery module only. A complete working battery system requires compatible CQ7-S-50 Slave battery modules and a compatible Fox ESS inverter/system configuration.
