If the power goes out, because of extreme heat, fire or wild weather, there’s not usually much you can do about it. But if you’ve got a solar battery, you could keep the internet connected, the lights on and the fridge running thanks to blackout protection.
Determining how long your battery will last in a blackout comes down to understanding a few factors:
- The size of your battery – how much electricity can it store?
- Do you have ‘whole of house’ or ‘emergency’ blackout protection? – Whole of house keeps the electricity flowing to the whole house, while emergency power supply keeps the electricity on to some (not all) electrical circuits in your home
- How many and what appliances are running during the blackout?
- The size and energy efficiency of those appliances
- How much energy you’ve got left in your battery when the blackout hits
Assuming your battery was fully charged when a blackout hit, we’ve pulled together some likely scenarios. With a 4.8kWh battery system, you could power the TV, the fridge and freezer and your kitchen and living room lights for around 10 hours*.
Blackout protection included at no extra cost
If you’re getting a solar battery for security in a blackout, it’s important to be aware that not all batteries come with this feature.

Compatible with any existing solar system, you can set a ‘reserve capacity’ to make sure there’s always some energy reserved in your battery in case of a power outage, and at times of crisis you can set it to store 100% of the energy for an emergency.
