80% usable capacity and 10 W idle draw are planning allowances. Replace them with measured values where possible.

The useful question is “together.”

A station might run a fridge or a laptop individually but have less time available when you use both. Each device adds energy demand; devices used together also add running watts. The explorer uses the same calculation as the full planner, including one motor starting at a time.

Enough battery isn’t the whole answer.

Watt-hours determine stored energy. Watts determine output. A low-wattage station can have hours of theoretical battery energy and still be unable to run a heater or start a compressor. Tiles flag modeled output limits separately from energy. An estimated runtime never overrides that limit.

Make the assumptions yours.

Preset watts and time-in-use percentages are starting points. “33% time in use” spreads that appliance’s running demand over one-third of the backup window; it does not reduce the inverter output needed when the appliance switches on. Use the full planner to enter measured watts, quantities and startup demand. For a refrigerator, start with its energy label or a meter reading.
