FoxESS storage. Smart value.

FoxESS is a well-established, fast-growing battery and inverter brand in Australia, and its home batteries and hybrid inverters carry Clean Energy Council approval, which is the listing that accredited installers and government rebate schemes require. That CEC approval matters because it confirms each product has passed Australian electrical safety and performance testing and can be legally connected to the grid here. FoxESS systems use safe, long-life LFP (lithium iron phosphate) chemistry, which runs cooler and is more resistant to thermal runaway than older lithium formulations, and they carry strong warranties — from 10 years on the established EQ4800 module up to 12 years on the higher-density CQ6 and CQ7 batteries, each guaranteed to 70% capacity retention at the end of that term. For a household cycling a battery daily on solar, that mix of certification, stable chemistry and a long warranty makes FoxESS a dependable choice.

FoxESS is chosen for its strong price-performance rather than a premium badge, so households get proven technology without paying top-tier prices. Every FoxESS home battery uses LFP chemistry and offers 100% usable depth of discharge, meaning you can draw the full rated capacity each cycle instead of holding a reserve back, plus over 95% round-trip efficiency, so very little stored solar is lost between charging and discharging. The hybrid inverters are VPP-ready, letting you join a virtual power plant later to earn from feeding stored energy back to the grid. The CQ6 stacks 5.99kWh modules from 11.98kWh up to roughly 83.86kWh and comes with a 12-year warranty, one of the longest on any Australian home battery. For most Australian homes, FoxESS delivers the specifications that matter for everyday bill savings at a more competitive price than many premium brands.

Yes, FoxESS batteries are designed to expand, so you can start with a smaller system now and add capacity later as your usage, family or electric-vehicle charging grows. The systems are high-voltage stackable, which means extra battery modules clip onto the existing stack rather than needing a separate second battery, keeping the install tidy and cost-effective. The EQ4800 stacks 2 to 9 modules for 9.32–41.93kWh usable, the CQ6 scales to roughly 83.86kWh, and the newest CQ7 reaches roughly 97.44kWh per stack, all paired with a FoxESS H3 or KH hybrid inverter that manages both solar and battery. Because the inverter and platform stay the same as you grow, expanding is straightforward. It is still worth sizing your initial system with an installer, as the modules you can add depend on your specific battery model and inverter capacity.
