EQ4800 or EP11?
Fox ESS also makes the EP11, a single-cabinet battery. Here's how they compare.
| EQ4800 | EP11 | |
|---|---|---|
| Design | Stackable modules | Single cabinet |
| Grows in steps of | 4.66 kWh | 10.36 kWh |
| Maximum | 41.93 kWh | 4 cabinets in parallel |

Warranty energy is how much power you can cycle through the battery under warranty. For the EQ4800 it covers a little more than one full charge a day for 10 years.
What a Fox ESS battery does for your home
Your solar panels make the most power in the middle of the day, often when nobody's home to use it. A Fox ESS battery saves that extra energy so you can use it when you actually need it, like in the evening when power prices are at their highest.
Store your extra solar
Instead of sending surplus solar to the grid for a small feed-in credit, a Fox ESS battery keeps it for later. More of the power your panels make stays right where it belongs: in your home.
Power your evenings with sunshine
When the sun goes down, your Fox ESS battery takes over. Lights, dinner, the TV and the washing machine can all run on energy you stored during the day.
Lower your power bills
Every kilowatt-hour you use from your Fox ESS battery is one you don’t have to buy from the grid, especially during expensive peak times.
Keep the lights on in a blackout
Paired with a Fox ESS hybrid inverter set up for backup, your battery can keep essential circuits running when the grid goes down.
Earn from your battery
Fox ESS batteries can join a virtual power plant, so your battery can earn you credits by helping support the grid at busy times.
Ready for an electric future
Thinking about an EV, a heat pump or an induction cooktop? Fox ESS batteries are expandable, so your storage can grow as your home goes electric.

Works with your Fox ESS inverter
Fox ESS batteries are high-voltage systems designed to pair with Fox ESS hybrid inverters. The EQ4800 works with the H1-G2, KH, H3-Smart and H3-Pro ranges.
Already have solar? We'll check your existing inverter and tell you whether you need a Fox hybrid inverter as part of the upgrade.
Installed safely, to Australian standards
The cables between a high-voltage battery and its inverter need proper mechanical protection. Every Solar Battery Group install fits Fox ESS cable covers as standard, using Solar Accreditation Australia (SAA) accredited installers.
Have a Fox ESS system without cable covers? Talk to us. Fox ESS supplies replacement covers free of charge.

Yes. The EQ4800 stacks in 4.66 kWh modules, up to nine per stack (41.93 kWh). We’ll leave room for expansion in your design.
Yes. It’s rated IP65, so it’s dust-tight and protected against water jets. We’ll recommend a spot out of direct afternoon sun.
It discharges down to −10 °C and charges from 0 °C. In very cold conditions charging may slow, which is normal for lithium batteries.
Fox ESS batteries are high voltage and designed for Fox ESS hybrid inverters. Most other-brand batteries and inverters won’t pair with them, so we’ll check your setup first.
In Australia, the EQ4800 has a 10-year warranty guaranteeing at least 70% of its capacity, covering more than one full charge cycle a day.
