PLAN WHAT YOU NEED

Start with
your essential loads..

Turn appliance watts and time in use into a transparent daily energy plan.

Power now. Energy over time.

A load plan keeps appliance running watts, watt-hours over time and starting requirements separate.
Illustrative arithmetic for one assumed load: 100 W for 2 hours at 100% duty uses 200 Wh. Running power, daily energy and starting demand answer different questions. Build a load plan

YOUR APPLIANCES, YOUR ASSUMPTIONS

Build your load list.

Use the running watts from your appliance label or a measurement. Hours describe time available each day; duty describes the percentage of that time it draws the listed power. For an appliance with no extra starting load, enter its running watts in the start field.

Keep this plan with a project.

Read the numbers together.

W measures power at a moment; Wh measures energy over time. A battery’s published capacity does not establish usable runtime, and an inverter’s continuous rating does not establish its starting-load capability. Check the exact equipment’s limits and source conditions.
