PV input is published as voltage and current rather than a direct wattage ceiling, so solar input stays unknown instead of being inferred.

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%	4h 38m	estimated
CPAP without heated humidifier	40 W at 100%	19h 6m	estimated
Starlink Mini	32 W at 100%	1d 1h	estimated
Wi-Fi router	12 W at 100%	2d 17h	estimated
Laptop	60 W at 100%	13h 11m	estimated

Good fit when

Capacity is best suited to lighter essentials such as routers, laptops, CPAP planning, lights, and smaller camping loads.
Tracked AC output is 1,000 W, so high-draw appliances and tools need careful filtering.
USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.

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, solar input.
