Terry KS Fox ESS has launched the CQ6 High Voltage Storage Battery, a compact and scalable energy storage solution designed to support Australia’s clean energy transition. The system aligns with government incentive programs and upcoming policy changes, enabling households and businesses to maximise solar usage and energy independence.
AUSTRALIA, 6 JANUARY 2026 – Fox ESS, a global renewable energy solutions provider, has launched its new CQ6 High Voltage Storage Battery, marking a significant step forward in energy storage technology for the Australian market. Designed to deliver higher energy density in a compact form, the CQ6 offers up to 48 kWh of capacity with eight modules in a single stack, aligning with the upper eligibility threshold of the Australian Government’s Cheaper Home Batteries Program.
Engineered for performance and faster economic returns, the CQ6 achieves over 95% round-trip efficiency with a full 100% depth of discharge, enabling users to maximise usable energy and shorten payback periods. Its streamlined, space-efficient design also simplifies installation, potentially reducing installation time by up to two hours compared to conventional battery systems.
The CQ6 supports a wide range of Fox ESS inverters, including the H1-G2, KH/HA Series, and H3 Series, offering strong system compatibility and scalability. Each stack uses 5.99 kWh battery modules and can be expanded from 11.98 kWh to 83.86 kWh. When combined with the H3 Plus inverter, up to three stacks can be deployed to deliver a total capacity of 251.58 kWh, making the solution suitable for residential, commercial, and industrial applications.
Industry leaders view the CQ6 as a timely innovation as Australia advances its clean energy agenda. Smart Energy Council CEO John Grimes noted that the battery’s efficiency, high density, and modular design make it well suited for households and businesses seeking to increase solar self-consumption and reduce grid reliance amid rising daytime renewable generation.
The CQ6 is also positioned to benefit from upcoming policy developments, including recent updates to the Cheaper Home Batteries Program and the Solar Sharer Offer scheduled to commence on 1 July 2026. Under the Solar Sharer Offer, residential users in New South Wales, South East Queensland, and South Australia will receive a minimum of three hours of free daytime electricity, creating new incentives for energy storage adoption. Solutions such as the CQ6 are expected to play a key role in energy balancing, virtual power plant participation, and integration with platforms like Amber, Evergen, and Synergy.
Fox ESS CEO Michael Zhu said continued policy support from the Federal Government and industry bodies remains critical to accelerating Australia’s clean energy transition. He added that Fox ESS will continue to focus on developing reliable and efficient energy storage solutions to help households and businesses achieve greater energy independence and sustainability.
