Enter your battery/UPS capacity and appliances. The calculator estimates runtime and helps you decide what to keep running during an outage.
1. Enter your battery/UPS capacity in Wh.
2. Set the usable battery percentage and inverter efficiency.
3. Add your appliances and their approximate wattage.
4. Enter how many hours the backup needs to last.
5. Press Calculate Power Plan.
The app estimates total electrical load and backup runtime, then identifies which appliances consume the most power.
Tip: During an outage, reducing high-power loads generally increases backup runtime.
