Battery sizing & design
We analyse your household usage profile and solar production data to recommend the right battery size for your needs and budget.
Store your energy.
Use it on your terms.
Battery storage lets you capture the surplus energy your solar system produces during the day and use it at night, during peak tariff periods, or when the grid goes down. True energy independence starts here.

"Adding a battery has completely transformed how we use solar.
We're virtually off-grid now and our bills have dropped to almost nothing."

Common questions
Do I need solar to add a battery?
You can install a battery without solar to take advantage of off-peak tariffs, but the best returns come from pairing battery storage with a solar system.
How long will a battery power my home?
This depends on your battery size and household consumption. A typical 10kWh battery will run essential loads for 8–16 hours during an outage.
What brands do you install?
We install Tesla Powerwall, Sungrow SBR, and other tier-1 systems. We recommend the best fit for your specific setup and budget.
Can I add a battery to my existing solar?
In most cases yes. We assess your existing inverter and system to determine the best integration approach.
