What do you want to power?

Start with an example or build your own list. Every value is editable.

Examples are illustrative inputs, not measured appliance consumption. This planner uses the AC energy path for US 120 V devices. Check your actual ports and appliance requirements. Read the method.

The calculator needs JavaScript to process your inputs locally. You can still browse model specifications, the default comparison and our method.

Your devices

Blank means unknown. For cycling devices, use energy per day instead of treating maximum watts as an average.

Add a device to start your estimate.

Choose an example above or add your own device. You can leave an uncertain value blank.

Energy assumptions

These editable starting assumptions are not measurements of any model. All listed devices are treated as simultaneous AC loads. Idle draw is deducted for the full planning period, even when a device is off.

Usable charge range (%)

Conversion efficiency (%)

Assumed idle draw (W)

Estimated device energy = rated Wh × charge range × efficiency − idle W × days × 24, floored at zero. Idle W is an output-equivalent modelling allowance. No charging, solar input or extra battery is included. Starts are checked one device at a time; simultaneous starts need a separate check.

Your inputs are saved only in this browser, until you clear them. They are not put in a shareable URL. Privacy details.
