Generator Sizing: How to Calculate the Correct KVA for Your Load
Choosing the right generator size is critical to avoid equipment damage, costly failures, or inefficient operation. This guide explains the difference between kW and kVA, categorizes load types (resistive vs. inductive), and provides a step‑by‑step calculation method—including the industry‑standard formula that accounts for motor starting surges. With a real‑world example and key considerations like altitude, temperature, and duty cycle, you’ll learn how to determine the exact kVA rating needed for reliable and cost‑effective backup or continuous power.
