The kVA Calculator for AC Units precisely determines the required running and starting kVA based on Tonnage, RLA, or kW inputs. It is essential for Compressor Surge Protection, ensuring your generator handles the high Locked Rotor Amperage (LRA) during startup, and provides Accurate Generator Sizing by calculating the total load kVA plus a customizable safety margin for reliable backup power.
