Verify the inputs
Measure or document each input. If a value is only an estimate, record its source and test a conservative alternative.
Independent energy/ CALCULATOR
Daily electricity budget
Add three appliance groups using power and actual daily running time.
FROM ESTIMATE TO ACTION
Use the result, not just the number.
Keep the calculation traceable
Save the input link or copied result together with the date, units and assumptions. A number without its inputs cannot be checked later.
Confirm the decision
Compare the estimate with the related guide, current product data and requirements that apply at your location before buying or building.
Inputs to verify
- Continuous essentials (W)
- Router, controls and standby loads.
- Essentials operating time (h/day)
- Use actual average time.
- Pump or cycling appliance (W)
- Running power; starting surge is separate.
- Pump operating time (h/day)
- Total time running, not time connected.
- Other appliance group (W)
- For example lights and a workstation.
- Other group operating time (h/day)
- Use a measured daily equivalent for cycling loads.
