BATTERY STORAGE

Battery storage.
On your terms.

Store solar. Charge cheaply. Keep your home powered.

Keep your solar. Add the storage.

Already generating your own electricity? An AC-coupled battery can be added alongside your existing solar system, so you can store more of what you generate and use it later.

KEEP YOUR EXISTING SYSTEM

Your panels and solar inverter can stay exactly where they are.

ADD BATTERY STORAGE

A separate battery system works alongside your existing solar.

USE MORE OF YOUR ENERGY

Store surplus generation during the day and use it later.

Adding a battery to existing solar

Keep your FIT. Keep more of your solar.

If your export payments are based on deemed export, adding a battery can let you store more of the solar you generate — without reducing those deemed export payments.

Battery storage for FIT customers
Solar

Your panels generate electricity.

Your home

You use what you need, as you need it.

Battery

Surplus solar is stored instead of leaving straight away.

Use it later

Power your home in the evening from stored solar.

The grid

Surplus is exported to the grid.

Any remaining surplus still goes to the grid.

Store more of your solar. Use it later.

Your FIT and deemed export payments continue either way.

*Applies where FIT export payments are deemed rather than metered. We’ll check your existing arrangement before recommending a system.

No solar? No problem.

A home battery can charge from the grid when electricity is cheaper, then power your home later when electricity costs more. No panels required.

CHARGE CHEAP

Top up your battery during lower-cost periods.

USE IT LATER

Power your home from stored electricity when rates are higher.

Your battery. Working smarter.

Your battery can respond to your energy tariff, solar generation and how your home uses electricity — deciding when it makes sense to charge, store, use or export.

CHARGE

Top up from the grid when electricity is cheaper.

STORE

Keep solar or low-cost electricity for later.

USE

Power your home when buying from the grid costs more.

SELL

Export energy when it makes sense to do so.
