Size your off-grid system in two minutes
Tick what you run. We work out the battery, panels and inverter you need, then match it to a complete kit with a real price.
What do you want to run?
Start with the setup closest to yours, then adjust anything. No watts to look up.
Enter your heaviest day of the year, usually summer with the air-con running, so the battery is sized for your biggest day.
Where are you, and how much backup?
Off-grid systems are sized for winter sun, which is much stronger up north than down south.

How we sized this
What Australian off-gridders say
"They have so far outperformed any of my previous AGM/Lead-acid batteries with around 10ah above the rated capacity."
"Last week our neighbours had a blackout and we didn't even know except for all the houses in the street were dark except for ours."
"These guys not only shipped it to me within 2 days but they also were happy to answer any questions I had when setting it up."
Sizing follows the LiFePO4 OZ off-grid sizing guide. It is a first-pass estimate, not electrical advice. Final design and installation must meet AS/NZS 5139 and be completed or signed off by a licensed, accredited electrician.
