SIZING TARGET

LED light

Default appliance profile before model-specific measurements.

60 Wh daily energy10 W startup target87 Wh 1-day nominal target

For the supplied profile, the 10 W LED light uses about 60 Wh per day (6 hours at a 100% duty cycle). Applying the stated inverter-efficiency, usable-capacity and reserve assumptions produces a conservative one-day target of about 87 Wh nominal capacity.

The power station should support at least 10 W of continuous output and 10 W of startup demand. Actual consumption may vary by appliance model, settings and conditions; no model-specific measurement is supplied.

  • Minimum sizing: Use about 87 Wh nominal capacity for one conservative day of this load.
  • Example capacity: The supplied profile estimates 300 Wh as about 4 default-profile days, or 23.8 hours at continuous draw.
  • Before buying: Include other simultaneous household loads when sizing a complete backup setup; a plug-in power meter or manufacturer energy label is preferable when available.

Using the default load profile, led light consumes about 60 Wh/day. A conservative one-day battery target is about 87 Wh nominal capacity, while the inverter should cover at least 10 W of startup demand.

Assumptions behind the calculation

  • Running draw: 10 W
  • Startup/surge: 10 W
  • Default use: 6 h/day
  • Duty cycle: 100%
  • Usage uncertainty: ±10% before model-specific measurements

Actual energy use varies by appliance model, ambient conditions, settings and load. A plug-in power meter or manufacturer energy label is preferable when available.
