Solar & Battery Solutions for Sydney Homes
Whether you already have solar or are planning a new system, the right solution starts with understanding your energy usage, existing electrical infrastructure, backup priorities and future energy needs.
Add a Battery to Existing Solar
Already have rooftop solar? We assess your existing solar system, electricity usage, switchboard and backup requirements to determine suitable battery options and how they can be integrated with your existing system.
New Solar + Battery Systems
Planning a new system? We design the solar and battery together around your household energy usage, roof space, electrical infrastructure, backup priorities and future energy needs.
Why Install a Home Battery?
A home battery can help you use more of the solar energy you generate, reduce reliance on grid electricity, provide backup capability where suitable, and prepare your home for changing energy needs.
Use More Solar
Store excess solar generated during the day for use later when your home needs it.
Reduce Grid Reliance
Use stored energy when solar generation is low or grid electricity is more expensive.
Backup Power Options
Suitable battery systems can provide backup power for selected circuits or household loads during an outage.
Prepare for Future Loads
Battery storage can support changing household needs such as EV charging and increased electrification.

We work with established battery manufacturers and select suitable options based on your existing solar system, household energy use, backup requirements, electrical infrastructure and installation conditions.

Choosing the Right Battery for Your Home

How much electricity your household uses and when that energy is consumed.
Existing Solar & Electrical System
Your solar system size, inverter configuration, switchboard and available electrical capacity all influence suitable battery options.
