Storms take out power across Newcastle and the Hunter most years. Backup is one of the main reasons people buy a battery — and one of the most misrepresented features in the industry.
Backup ready is not backup
A battery described as backup capable may still need a dedicated backup circuit, a changeover device and extra wiring to actually keep anything running. If that work isn't in the quote, you won't have backup. Always ask which specific circuits will stay live.
Essential circuits backup
A selected group of circuits — such as a fridge, lights, selected power points and internet — can be designed to stay live. The actual circuits and expected duration depend on their measured loads, inverter output and usable stored energy.
Whole-home backup
A broader backup design may keep more circuits available, but every simultaneous and starting load must remain within the selected inverter's continuous and surge limits. No model guarantees that a property will carry on as normal during every outage.
How to choose
- List the circuits you need and measure their simultaneous and starting loads.
- Confirm the selected inverter's off-grid continuous and surge output in writing.
- For critical or medical equipment, use purpose-specific continuity arrangements rather than relying on a general home battery promise.
We scope backup circuits during the site visit and put them in writing. You'll know exactly what stays on before you agree to anything.
