Answer a few questions about your appliances and your AC backup needs β we’ll estimate the inverter and lithium battery size that fits.
Everyday appliances
Tell us how many of each you’ll run. These are assumed to run continuously during backup.
Occasional-use appliances
These only run in short bursts, even during an outage β set how many minutes each will realistically run.
Air conditioners
ACs are usually the biggest single load in the house β we size these separately.
Backup runtime
How many hours do you want your ACs to run on battery during an outage (e.g. overnight)?
6 hours
And your other appliances (lights, fans, fridge, TV etc.) β how long should those run on battery too?
4 hours
Your estimated system
Based on what you told us β here’s the ballpark inverter and battery size.

This is a rough sizing estimate based on typical appliance wattages, built to give you a starting point β not a substitute for a proper site load audit. Actual requirements vary with real appliance ratings, wiring, inverter efficiency, and battery depth-of-discharge. Confirm exact sizing with our team before ordering.
