- It checks startup surge against inverter surge, and says a passing wattage check does not verify startup duration or adapter compatibility.
Field notes
The calculator offers preset loads, including CPAP configurations with and without humidification, as well as a fridge-outage scenario. Users can change appliance wattage and hours, then tune assumptions such as reserve margin and peak sun hours. The page cautions that its figures are not lab runtimes and that a wattage pass does not establish startup duration, adapter compatibility, or uninterrupted power.
