REAL-WORLD RUNTIME
How Far Does a 25 kWh Battery Actually Go?
For the average Australian home, a 25 kWh solar battery doesn't just cover the essentials — it changes how you live. Because a typical household uses around 15–18 kWh a day, this capacity holds more than enough power to run your home for over 24 hours straight completely off the grid.
Run your air conditioning, use the electric oven, and power through the expensive evening peak entirely on your own terms. Even after heavy evening use, you’ll have a reliable energy buffer keeping your fridge, lights, and essential appliances running securely until your solar panels begin recharging the next day.

Frequently Asked Questions
Most Australian households are well suited to a 25–30 kWh system — typically enough to cover overnight usage using solar energy generated during the day. Speak with a specialist during your welcome call. We can provide a more accurate recommendation using your latest electricity bill.
Yes. Every advertised price includes the battery, hybrid inverter, standard installation by an SAA-accredited installer, app setup, and the federal Cheaper Home Batteries rebate already applied.
Additional site-specific work — such as switchboard upgrades, concrete slabs, or difficult access requirements — may incur extra charges, but these are quoted separately and only proceed with your approval.
Your installation date is scheduled once your property passes compliance review, which usually occurs within a week of receiving your site photos. We’ll work with you to arrange a suitable installation date.
Our batteries, including systems and parts, come with a 10-year warranty.
Yes. The federal Cheaper Home Batteries rebate requires an existing or connected solar system.
If you do not currently have solar, mention it during your welcome call. We work with installation partners who can install both solar and battery systems together, often reducing additional labour and installation costs.
Most Australian homes use single-phase power. Larger homes may use three-phase power, which is what the VoltX Energy Whale Solar Battery is designed for.
If you are unsure, your welcome call will confirm compatibility, and we can adjust your system recommendation if needed.
The Cheaper Home Batteries Program (effective 1 May 2026) provides an upfront, tiered rebate based on battery capacity:
- Approximately $252 per kWh for the first 14 kWh
- Approximately $151 per kWh for the next 14 kWh
- Approximately $38 per kWh for capacity between 28–50 kWh
We apply the rebate directly to your quoted price, so there is no paperwork to complete and no waiting for a tax-time refund.
