Your battery is already
built for more.
GridPiggy.energy is being developed specifically around the experience of existing FoxESS battery owners — adding a smarter service layer around compatible systems, not asking you to replace the hardware you already own.
A great battery.
A clearer way to use it.
GridPiggy is designed to turn a capable home battery into a smarter energy asset.
Your FoxESS battery already stores energy for your home. The goal is to help you use that stored energy more intelligently — prioritising household savings first, while exploring future opportunities for eligible batteries to support the wider energy system.
No replacement battery. No noisy complexity. Just a clearer way to get more value from the hardware you already own.
- Works with the FoxESS system already installed at home
- Household savings are the first priority
- Future flexibility only where a system is eligible
- Nothing changes without clear information and consent
Availability, compatibility and service features will depend on technical validation and program terms.
Stored energy is valuable.
Timing makes it smarter.
The value of electricity changes throughout the day. Solar production, household demand and grid conditions rarely line up perfectly.
A battery helps bridge that gap. Without intelligent coordination, opportunities to reduce grid consumption or respond to changing energy conditions may be missed.
- Store more of the energy you generate.
- Use stored energy when it benefits your home.
- Prepare for future grid participation where available.
Store it now.
Use it when it counts.
Think of your home battery as an energy piggy bank. Solar energy goes in when it is available. Stored energy comes out when your home can make better use of it.
Your energy. Your battery. Smarter timing.
Your FoxESS hardware stays
where it is.
GridPiggy is intended to add a smarter service layer around compatible systems. The goal is not to make energy more complicated. It is to make better decisions quietly in the background.
- Built around existing FoxESS owners
- Household-first service intent
- Future features subject to validation
