Foxess have become one of Australia's most-installed battery brands thanks to a strong product warranty, an open API, and competitive cost per usable kWh. The two flagship lines for Australian homes are the modular CQ series and the all-in-one EQ series.
The CQ6 is a stackable LFP battery that scales from 12kWh to 48kWh in 6kWh modules. It pairs with the H3 hybrid inverter for single or three-phase, supports full off-grid backup, and is the system we install most often on acreage and EV-charging households.
The EQ4800 is a 4.8kWh wall-mounted unit aimed at smaller homes that want straightforward solar self-consumption without backup. It's typically $2,000–$3,000 cheaper installed but doesn't expand and doesn't run a whole home in a blackout.
We break down the cost-per-kWh, payback period under the 2026 federal battery rebate, and which households win with each option.
