Battery Sizer helps you understand what size battery your home actually needs — not a guess, but a practical estimate based on your real usage. By entering a few simple details about your solar system and daily electricity consumption, the tool calculates a recommended battery capacity and module setup that matches your lifestyle.

It’s designed to remove the confusion around battery storage. Instead of overspending on a system that’s too large — or installing one that’s too small — Battery Sizer gives you a clear starting point for a smarter investment, helping you maximise your solar energy and reduce reliance on the grid.
