Fox ESS Launches CQ6 HV Battery to Enhance Residential Energy Storage Performance
Fox ESS has officially unveiled its new CQ6 High Voltage (HV) Storage Battery, designed to meet the growing demand from Australian households and businesses for higher-capacity energy storage, faster payback, and simpler installation.
Launched in late December, the CQ6 arrives at a pivotal time for Australia’s clean-energy transition, as more homes move toward electrification and seek to maximise the value of their rooftop solar systems.
High-Density Design Built for Australian Homes
The Fox ESS CQ6 features a dense, modular architecture that allows up to 48 kWh of usable storage in a single compact stack using eight modules. This capacity sits neatly at the upper eligibility limit of the Federal Cheaper Home Batteries Program, making it an excellent choice for:
- Large family homes
- Multi-dwelling residences
- Small commercial sites
- Properties with high evening or overnight energy use
By storing more daytime solar energy, households can significantly reduce grid reliance and improve long-term savings.
Designed for Faster Payback
Performance is a standout feature of the CQ6 battery system.
Key efficiency benefits include:
- More than 95% round-trip efficiency
- 100% depth of discharge (DoD)
This means homeowners can access almost all the energy they store, rather than losing usable capacity to battery protection limits. Higher usable energy translates directly into better solar self-consumption and faster return on investment, particularly as electricity prices continue to rise.
Faster, Simpler Installation
Fox ESS has placed a strong focus on installer efficiency with the CQ6 design. Its compact footprint and streamlined stacking system can reportedly save one to two hours per installation compared to traditional high-capacity batteries.
This makes the CQ6 suitable for:
- Suburban Melbourne homes
- Regional Victorian properties
- Commercial and light-industrial sites
Less labour time also means lower installation costs and fewer disruptions for homeowners.
Built for Scale and Compatibility
Each CQ6 module delivers 5.99 kWh, allowing flexible configurations from 11.98 kWh up to 83.86 kWh per stack.
When paired with the H3 Plus inverter, up to three stacks can be connected, delivering a total system capacity of 251.58 kWh.
The CQ6 is compatible across the Fox ESS inverter range, including:
- H1-G2 series
- KH series
- HA series
- H3 models
This broad compatibility makes it suitable for new solar installations and battery retrofits alike.
Industry Backing and Market Timing
John Grimes, CEO of the Smart Energy Council, highlighted the importance of the CQ6 launch for Australia’s energy future:
“The CQ6 is a game-changer for Australia’s clean energy transition. Its high density and efficiency, along with modular scalability, make it perfect for homes and businesses aiming to maximise solar self-consumption and reduce reliance on the grid.”
Ready for Evolving Energy Policies
The CQ6 has been designed to align with major policy developments, including:
- Updates to the Cheaper Home Batteries Program
- The upcoming Solar Sharer Offer, launching 1 July 2026
Under the Solar Sharer Offer, retailers in NSW, south-east Queensland, and South Australia will need to provide at least three hours of free daytime electricity. High-capacity batteries like the CQ6 allow households to store that free energy and use it later during peak-price periods.
The system also supports Virtual Power Plant (VPP) participation and integrates with platforms such as Amber, Evergen, and Synergy, giving users greater control over how and when their stored energy is used.
A Strong Product Lineup for Australian Conditions
While Fox ESS continues to expand globally, its Australian product range already includes high-performance inverters and batteries built for local conditions. The CQ6 builds on this foundation by offering higher-density storage without compromising safety, flexibility, or efficiency.
For homes and businesses navigating:
- Rising electricity prices
- Changing feed-in tariffs
- New rebate structures
- Increased electrification
…the CQ6 represents a compelling next-generation storage solution.
