Fox ESS CQ7-S Expansion Module (without BMS, 7.02 kWh)

An additional (Slave) battery module with a capacity of 7.02 kWh, designed for expanding CQ series high-voltage systems. The CQ7-S model does not include its own Battery Management System (BMS) and is engineered exclusively to connect to the master module (CQ7-M). This allows you to significantly save on costs when scaling up your solar station's capacity, as you avoid paying extra for redundant control electronics.

Advantages:

• Cost-Effective Expansion: More affordable than the Master module, making system capacity scaling highly budget-friendly.

• Easy Integration (Stackable): The modules easily stack on top of one another and connect with simple cables, forming a clean and compact battery tower.

• Seamless Synchronization: The module is instantly recognized by the system and operates completely under the commands of the master unit's BMS.

• Premium LiFePO₄ Cells: Guarantee high efficiency and a service life of over 10 years.

Ideal For:

• Customers who already own (or are purchasing) the CQ7-M master module and want to increase their system's total energy storage capacity to 14, 21, 28+ kWh.
