Know What Your Backup Power Can Actually Cover

Enter your battery capacity and the devices you want to keep running. The calculator helps estimate your energy requirements and shows how your available battery capacity compares with your planned 24, 48 or 72-hour needs.

You can adjust the assumptions to match your own equipment and priorities.

Designed for Real-World Planning

Use the toolkit to answer practical questions such as:

How much energy will my essential devices need?
How long might my battery supply last?
Which devices should I prioritise?
Could solar recharging extend my backup time?
Where are the biggest gaps in my outage plan?

No complicated electrical calculations are required — the spreadsheet does the basic energy planning for you.
