Will my solar work in a blackout?
Standard solar without a battery shuts down when the grid goes down, for safety. To keep power on you need a battery set up with backup, and in many setups the solar can keep charging the battery during the day.
What's the difference between essential circuits and whole-home backup?
Essential-circuit backup covers a few chosen circuits, like the fridge, lights and internet. Whole-home backup covers the whole switchboard, where the battery and board allow. Whole home is more convenient; essential circuits stretch the battery further.
How long will a battery run my house in a blackout?
It depends on how much is stored when the power goes out and what you're running. Lights, fridge and internet use far less than air con or an oven. We'll talk through your usage and can set a backup reserve so there's always some charge kept aside.
Can I add backup to a battery I already have?
Sometimes. It depends on the battery, inverter and switchboard. Some systems need a gateway or backup switch added. We'll check what you've got and tell you what's possible.
Is backup the same as going off-grid?
No. With backup you stay connected to the grid and the battery only takes over when the grid drops out. Off-grid means no grid connection at all, so the system has to be much bigger and usually includes a generator. See our off-grid solar page.
Does the battery rebate cover backup wiring?
The federal rebate covers the battery itself. Backup wiring, gateways and switchboard work are separate lines on your quote. Our battery rebate guide explains how the rebate is worked out.
Can I run air con during a blackout?
Sometimes, but it uses a lot of power and can drain the battery quickly. A small split system is more realistic than ducted. We'll tell you honestly what your battery can handle.
Do you install backup batteries outside Adelaide?
Yes. We work right across South Australia, including the Adelaide Hills, Fleurieu, Kangaroo Island and regional areas, with install partners in the South East, Yorke and Eyre Peninsulas. Every job is designed, managed and signed off by NG Elec.
