answers 402

Cable loss uses the DC resistance of the two-way run at twenty degrees Celsius; warm cable in a hot compartment carries roughly four percent more resistance per ten kelvin, which is not applied. Inverter loss follows a three-part model of idle draw, a proportional share and a quadratic share, fitted so that the stated peak efficiency is met near half of the rated power.
