Australian households are hungry for better control over their energy use, especially with rooftop solar now doing most of the daytime heavy lifting. The missing piece is often reliable battery storage that keeps the home running smoothly after sunset. The Fox ESS EQ4800 steps into that gap with a modular, climate-ready design that grows with your needs, trims your bills, and keeps your solar power working harder for you.
What is the Fox ESS EQ4800?
The Fox ESS EQ4800 is a high-voltage, modular lithium-iron-phosphate home battery that stores excess solar energy for later use. It works with compatible Fox ESS hybrid inverters to provide safe, long-lasting, and efficient storage. You can start with one module, then expand the stack as your home adds more appliances, boosts energy use, or introduces an EV. It’s designed for homeowners who want flexibility, reliability, and long-term value.
Why it suits Australian households
The EQ4800 shines in Australian conditions. Its LiFePO4 chemistry offers strong thermal stability, and its wide operating temperature range suits everything from Melbourne’s frosts to Queensland’s humidity. With full usable capacity and high efficiency, more of your solar power reaches your appliances instead of being wasted. This helps households cut peak-hour bills and reduce grid reliance throughout the year.

Real-world benefits for Aussie homes
The EQ4800 fits a wide range of households. Smaller homes can begin with a single battery module, while larger families can build a full stack to cover nighttime use, EV charging, and high-load appliances. Its strong weather resistance and safe battery chemistry make it reliable in the harshest climates. Because it delivers full usable energy with minimal losses, families get more bang for their solar buck, especially during expensive evening peak periods.
A long cycle life adds peace of mind, ensuring the system delivers consistent performance for many years. Households wanting a future-ready setup appreciate its modularity, allowing easy expansion without replacing the whole system.
Where it fits best
The EQ4800 suits homes that:
- Want to start small and expand later
- Plan to add EV charging in future
- Want to reduce evening grid costs
- Prefer safe, stable LiFePO4 chemistry
- Need a climate-ready battery with strong protection ratings
Things to keep in mind
You will need a compatible Fox ESS hybrid inverter, and any expansion of modules must be handled carefully to keep voltages aligned. As always, a quality installer makes the biggest difference in long-term performance.
A standout choice
The Fox ESS EQ4800 blends safety, scalability, efficiency, and affordability into a battery system that adapts with your household. For Australians wanting to unlock the full value of their solar, cut bills, and future-proof their home, this battery is a standout choice.
