Keep Your Home Powered During a Power Cut
Solar panels and batteries don't automatically mean your home will stay powered when the grid goes down.
Find out what your home needs to keep the essentials running during a power cut.
A battery isn't automatically a backup.
One of the biggest misconceptions about home energy is that having solar panels or a battery automatically means your home will stay powered during a power cut.
That isn't necessarily the case.
Backup power needs to be considered as part of the system design. The right approach depends on your battery and inverter, electrical setup, backup equipment, the parts of your home you want to keep running and how much power they require.
When the grid goes down, what would you want to keep running?
Fridge & freezer
Wi-Fi
Lighting
Heating controls
Security systems
Home office
Essential sockets
Other critical equipment
Backup power can be designed around the things that matter most to you, rather than simply trying to power everything.
What happens when the grid goes down?
Without backup
- Grid goes down
- Your solar or battery system may disconnect
- Your home loses power
With properly designed backup
- Grid goes down
- The backup system responds
- Stored energy becomes available
- Selected parts of your home can remain powered
Solar. Battery. Backup. Designed as one system.
Solar generation
Generates electricity during daylight hours and can form part of the wider home energy and backup strategy when the system supports it.
Battery storage
Stores energy so it can be available when needed.
Compatible inverter technology
Helps manage the flow of energy between solar, battery, the home and the grid. Backup capability depends on the equipment and system design.
Backup / changeover equipment
Allows an appropriately designed system to safely provide backup power when the grid is unavailable.
Essential circuits
Prioritise the parts of the home the homeowner considers most important during an outage.
Energy management
Helps understand and manage how stored energy is being used.
Whole-home backup or just the essentials?
Different homes have different backup requirements.
Just the essentials
For some homeowners, keeping these running may be enough:
- Lighting
- Internet
- Refrigeration
- Heating controls
- Security
More comprehensive backup
Others may want a more comprehensive backup solution.
That's why we start by understanding your property, your existing energy system and what you actually want to keep running, before recommending any equipment.
Your home needs a power security plan.
The right backup solution isn't about installing the biggest battery possible.
It's about understanding your home, deciding what matters during an outage and designing the system around it.
