Return on Investment (ROI) – Is It Worth It?
The most common question: Is installing a Fox ESS battery worth it in Sydney?
Potential Savings Breakdown

Evening usage bought at 30–45c per kWh
With a battery:
Store solar during the day
Use stored energy at night
Avoid peak grid pricing
For a typical Sydney home with a 6.6kW–10kW solar system:
Annual savings: $900 – $1,800
