Runtime Starting Points

These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Scenario	Default load	Estimate	Scenario confidence
Full-size refrigerator	500 W at 33%	7h 28m	estimated
CPAP without heated humidifier	40 W at 100%	1d 6h	estimated
Starlink Mini	32 W at 100%	1d 16h	estimated
Wi-Fi router	12 W at 100%	4d 10h	estimated
Laptop	60 W at 100%	21h 17m	estimated

Good fit when

Capacity is in a mid-size planning class that can cover many overnight or essential-load scenarios when reserve and efficiency are included.
Tracked AC output is high enough for many household plug-in loads, but surge still needs a separate check.
USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
Tracked solar input is 800 W before panel, weather, angle, and controller losses.

Watch out for

Surge output is tracked, but device startup behavior should still be checked against the actual load.
Still unknown in the source-backed record: usable capacity.
