| Question | Example | |
|---|---|---|
| Watts (W) | What can run at once? | A 65 W laptop and a 25 W monitor are 90 W together. Continuous AC output has to cover that. |
| Watt-hours (Wh) | How much energy is stored? | A steady 100 W device uses 100 Wh in an hour. A 1,000 Wh battery covers ten hours only in a lossless calculation. |
How we calculate
The line above is BLUETTI’s published AC180 formula. Where a manufacturer does not publish the factors, the planner uses 90% depth of discharge, 85% inverter efficiency, and 10 W of self-use. For cycling devices, average draw differs from running watts.

Estimates use manufacturer specs; real runtime varies with your device and temperature.
Three checks
- Does continuous output cover the devices that run together?
- Does stored energy cover the hours you need?
- Do the manufacturer’s startup limits match your appliances?
Solar input, charge speed, and expansion come after those three.
