Three simple moves

One battery.
Save. Event. Earn.

Your FoxESS battery powers your home first. When a GridPiggy Event begins, eligible battery flexibility can create additional value — and that value goes into your PiggyBank.

Save. Event. Earn.

Save

Your home comes first.

Your FoxESS battery stores energy and uses it when your home needs it most — helping you buy less electricity from the grid.

Event

GridPiggy spots an opportunity.

When energy prices or grid conditions create an opportunity, GridPiggy can run an Event using eligible battery flexibility.

Earn

The value goes into your PiggyBank.

The additional value created during an Event is recorded in your PiggyBank, where you can see what your battery has earned.

Self-consumption first. GridPiggy Events second. Extra value for you.

Solar and battery energy flowing to the home first, with the grid connected beyond it
Your home has priority

Rooftop to battery
to your home.

The order matters more than the technology. Energy reaches your household before anything else is considered.

Solar in, stored for later

Solar energy is captured while it is available and held in your FoxESS battery.

Your household, first call

Stored energy supports your home, reducing the electricity you buy from the grid.

Eligible flexibility, second

Only what is left over and eligible is ever considered for a GridPiggy Event.

Smart moments. Real value.

What happens
during an Event.

A GridPiggy Event is a short period when your battery can respond to an energy opportunity.

GridPiggy identifies the moment. Your compatible FoxESS battery responds. The value created is added to your PiggyBank.

Charge low

Store energy while it is cheap.

Grid energy becomes cheaper. Your battery charges at the lower price and holds that energy for a more valuable time.

More affordable energy stored for later.

Export high

Release it when the grid needs it.

The grid needs more energy and export value rises. Eligible stored energy is exported during the Event.

The additional value is added to your PiggyBank.

Event availability, operation and value vary by location, electricity plan, energy-market conditions and system eligibility.

Household energy needs come before any Event.

Clear program terms

Costs, Event value and conditions are provided before enrolment.
