Introducing the New Fox ESS Gateway: Keep Your Power On During a Power Cut

Most home battery systems in the UK automatically shut down during a power cut — even if your batteries are full. That means your stored solar energy is unavailable just when you need it most.

The new Fox ESS Backup Gateway changes that.

Stay Powered When the Grid Goes Down

The Fox ESS Gateway is a smart backup device that connects between your inverter and your home’s electrical system.

When a power cut occurs, it instantly isolates your property from the grid and switches over to battery power in less than a second.

When power is restored, it automatically reconnects and recharges your batteries as normal — all without any manual intervention.

This means essential circuits like lights, fridge, Wi-Fi, and heating controls can keep running seamlessly, even during an outage.

Seamless Integration with Fox ESS Systems

Developed by Fox ESS to work perfectly with their hybrid and AC inverters, the Gateway offers full plug-and-play compatibility.

• Works with new and many existing Fox ESS installations.
• Simple, tidy installation with no need for third-party backup units.
• Fully integrated with Fox monitoring apps, so you can track battery status, backup mode, and power flows in real time.

True Energy Independence

With grid instability and extreme weather events becoming more common, the Fox ESS Gateway brings peace of mind to homeowners and businesses alike.
You’re no longer just storing solar energy to save on bills — you’re gaining true energy security, powered by your own clean electricity.
