Fox ESS CQ7-80 Master Module

• Fox ESS CQ7-M-80 7.02kWh HV LiFePO4 Master Battery Module – Module Only

  Reference : CQ7-80-M

  Fox ESS CQ7-M-80 7.02kWh HV LiFePO4 Master Battery Module – Module Only

  The Fox ESS CQ7-M-80 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-80 Master module, combined with one or more compatible CQ7-S-80 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-80 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-80 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-80 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-80 is built for dependable performance in a wide range of installation environments.

  The Master module features a 80A 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-80 is the correct choice when building a new Fox ESS CQ7 battery tower or replacing/adding the required Master module in a compatible CQ7-80 system.

  Important: This product is the Master battery module only. A complete working battery system requires compatible CQ7-S-80 Slave battery modules and a compatible Fox ESS inverter/system configuration.

Fox ESS CQ7-80 Slave Module

• Fox ESS CQ7-S-80 7.02kWh HV LiFePO4 Slave Battery Module – Module Only

  Reference : CQ7-80-S

  Fox ESS CQ7-S-80 7.02kWh HV LiFePO4 Slave Battery Module – Module Only

  The Fox ESS CQ7-S-80 is a high-voltage Slave battery module designed for use within the Fox ESS CQ7 battery storage system. With a nominal capacity of 7.02kWh, 57.6V nominal voltage and advanced LiFePO4 battery technology, this module provides a reliable and scalable energy storage solution for residential and commercial solar applications.

  This product is supplied as one Slave battery module only. It does not include the CQ7 Master module/system controller. A complete Fox ESS CQ7 battery system always requires one CQ7-M-80 Master module together with one or more CQ7-S-80 Slave modules. The system can be expanded with up to 13 Slave modules, allowing a total storage capacity of up to 98.28kWh.

  The CQ7-S-80 is built for easy installation and flexible system expansion. Its modular, plug-and-play design helps reduce installation time, while CAN communication ensures efficient interaction with compatible Fox ESS hybrid inverters. The battery uses safe and durable Lithium Iron Phosphate chemistry, offering long service life, stable performance and excellent operational safety.

  Each CQ7-S-80 module offers a 122Ah nominal capacity, 80A maximum charge/discharge current, 65A peak discharge current for 60 seconds, and a wide operating temperature range. The compact module dimensions of 660 × 360 × 190mm and weight of approximately 50kg make it suitable for indoor and outdoor stand installation when used according to Fox ESS installation requirements.

  The Fox ESS CQ7 series is designed with multiple protection functions and an integrated fire protection function, supporting safe and reliable energy storage in demanding environments. With an IP65 protection rating, natural convection cooling and scalable high-voltage architecture, the CQ7-S-80 is an excellent choice for expanding an existing Fox ESS CQ7 battery tower or building a new high-voltage storage system with the required Master module.

  Important: This is a Slave battery module only. For a working battery system, a compatible CQ7-M-80 Master battery module/system controller is required.
