The Fox ESS CQ7 is a premium high-voltage battery storage system designed for homeowners and businesses looking for powerful, efficient and expandable energy storage.

Built around a modular 6.96kWh battery architecture, the CQ7 allows you to select the storage capacity that suits your property today while providing the flexibility to build a much larger system. Fox ESS specifies the CQ7 platform as scalable all the way to 97.44kWh, making it suitable for everything from residential solar storage to larger energy-demand applications.

For customers investing in solar and battery storage, the CQ7 combines the key features that matter: high usable capacity, LFP battery chemistry, high efficiency, strong charge and discharge capability, weather-resistant construction and a modular design that can grow with future energy requirements.

Why Choose the Fox ESS CQ7?

More Usable Energy with 100% Depth of Discharge

Fox ESS specifies the CQ7 with 100% depth of discharge (DoD). This means the nominal capacity and usable capacity are the same across the configurations listed in the manufacturer's datasheet.

For example, a 27.84kWh CQ7 system is specified with 27.84kWh of usable battery capacity.

For customers, this makes it easier to understand how much of the advertised battery capacity is actually available for energy storage.

High-Efficiency Energy Storage

Storing solar energy only makes sense if the battery can return that energy efficiently when it is needed.

Fox ESS specifies the CQ7 battery pack at greater than 95% round-trip efficiency under its stated test conditions of 25°C and 0.3C charging/discharging.

Higher battery efficiency means less energy is lost during the process of charging and discharging the battery.

Powerful 80A Charge & Discharge Capability

The CQ7 supports a maximum charge/discharge current of 80A, giving the platform substantial power capability as system capacity increases.

The manufacturer's datasheet lists nominal system power from 9.22kW on the 13.92kWh CQ7-L2 through to 32.26kW on the 48.72kWh CQ7-L7 configuration. Actual available current can vary according to temperature, cell voltage and state of charge.

Premium LFP Battery Technology

The CQ7 uses LFP (LiFePO₄) battery chemistry throughout the range.

LFP has become a widely used chemistry for stationary energy storage, making the CQ7 a strong option for customers wanting a modern lithium battery platform for their solar and energy-storage system.

Built to Grow with Your Energy Needs

One of the biggest advantages of the CQ7 is its modular architecture.

Rather than purchasing a completely different battery system when greater storage is required, the CQ7 platform uses individual 6.96kWh modules that are installed in series.

Every CQ7 system consists of:

1 × CQ7-M Master Module
plus
1 or more CQ7-S Expansion Modules

The CQ7-M contains both the battery module and the controller for the complete battery system. CQ7-S modules provide additional battery capacity. Each system must contain exactly one CQ7-M, with Fox ESS allowing up to 13 CQ7-S modules.

That provides a maximum system size of 14 modules and 97.44kWh.

Choose the Right Capacity for Your Property

This listing is available in six complete system sizes:

13.92kWh – CQ7-L2

A strong starting point for customers looking for substantial home battery storage without moving immediately into a very large system.

Store More of Your Solar Energy

A battery allows excess solar generation to be stored instead of being immediately exported when the property is not using it.

That stored energy can then be available later when solar production is lower, including during the evening or overnight, subject to the configuration of the overall solar, inverter and battery system.

With capacities ranging from 13.92kWh to almost 50kWh in this listing, the CQ7 provides options for properties with very different electricity consumption profiles.

A Battery System That Doesn't Lock You Into One Size

Energy requirements can change.

A household may add an EV, heat-pump hot water system, pool equipment or additional electrical loads. A business may increase its operating hours or equipment requirements.

The CQ7's modular architecture is designed to provide flexibility. Fox ESS specifically describes the CQ7 as a scalable battery storage system with additional batteries installed in series and a maximum capacity of 97.44kWh.

This gives customers a battery platform capable of accommodating much larger storage configurations than the systems offered in this particular listing.

High-Voltage Battery Architecture

The CQ7 is a high-voltage storage battery system.

As additional modules are installed, nominal system voltage increases. The configurations in this listing range from 115.2V to 403.2V nominal voltage.

High-voltage architecture is particularly well suited to modern compatible hybrid inverter and energy-storage systems where efficient transfer of substantial amounts of power is required.

Designed for Indoor or Outdoor Installation

The CQ7 offers flexibility when choosing an installation location.

Fox ESS specifies:

Ingress Protection: IP65
Installation Location: Indoor / Outdoor (Stand)
Cooling: Natural convection
Humidity: 5–95%, non-condensing
Maximum Altitude: 3,000m

Its IP65 rating makes the enclosure suitable for appropriately installed outdoor applications as well as indoor battery installations.

Wide Operating Temperature Range

Fox ESS specifies standard operating temperatures of:

Charging: 0°C to 55°C
Discharging: -10°C to 55°C

An optional warm-up version is also specified, extending charge and discharge operation down to -25°C under the conditions stated by Fox ESS.

Integrated Fire Protection Function

Fox ESS lists a fire protection function as part of the CQ7 system's protection specifications.

The system is also specified against IEC 62619 for safety, IEC 61000-6-1/2/3/4 for EMC and UN38.3 for transportation.

Clean, Space-Efficient Modular Design

The CQ7 uses a vertically stacked design rather than requiring multiple separate battery cabinets.

Each additional CQ7-S module increases the height of the system while maintaining the same 660mm × 360mm footprint specified in the datasheet.

This creates a clean, integrated battery tower while allowing significant amounts of storage capacity to be installed within a relatively compact footprint.

Plug & Play Installation Design

Fox ESS describes the CQ7 as using a plug-and-play solution designed to make installation easier and save installer time.

The modular approach also simplifies system configuration because capacity is increased through additional compatible CQ7-S modules rather than completely separate battery systems.
