Our generator KVA rating to amperage chart will help you determine the right KVA to KW or AMPs conversion that meet your power needs. For adequate power to your equipment, you’ll need a generator with adequate KVAs. The higher the KVA rating, the more power the generator produces. KVA (Kilovolt-Ampere) is the rating most commonly used to rate a generator’s power output. Generator KVA Rating to Amperage Conversion Chart This article incorporates public domain material from Federal Standard 1037C.6: "Special names for the unit of power: the name volt–ampere (symbol ‘VA’) when it is used to express the apparent power of alternating electric current, and var (symbol ‘var’) when it is used to express reactive electric power." ^ Council Directive on units of measurements 80/181/EEC Chapter 1.2.3., p.Electrical Machines, Drives and Power Systems.

Per EU directive 80/181/EEC (the "metric directive"), the correct symbol is lower-case "var", although the spellings "Var" and "VAr" are commonly seen, and "VAR" is widely used throughout the power industry. SI allows one to specify units to indicate common sense physical considerations. The unit "var" is allowed by the International System of Units (SI) even though the unit var is representative of a form of power. Special instruments called varmeters are available to measure the reactive power in a circuit. The term var was proposed by the Romanian electrical engineer Constantin Budeanu and introduced in 1930 by the IEC in Stockholm, which has adopted it as the unit for reactive power. Reactive power exists in an AC circuit when the current and voltage are not in phase. In electric power transmission and distribution, volt-ampere reactive ( var) is a unit of measurement of reactive power. The convention of using the volt-ampere to distinguish apparent power from real power is allowed by the SI standard. Transformers with the same sized core usually have the same VA rating. VA ratings are also often used for transformers maximum output current is then VA rating divided by nominal output voltage. For example, a (large) UPS system rated to deliver 400,000 volt-amperes at 220 volts can deliver a current of 1818 amperes (these are RMS values). When a UPS powers equipment which presents a reactive load with a low power factor, neither limit may safely be exceeded. The VA rating is limited by the maximum permissible current, and the watt rating by the power-handling capacity of the device. Some devices, including uninterruptible power supplies (UPSs), have ratings both for maximum volt-amperes and maximum watts. In the limiting case of a purely reactive load, current is drawn but no power is dissipated in the load. Where a reactive (capacitive or inductive) component is present in the load, the apparent power is greater than the real power as voltage and current are no longer in phase. With a purely resistive load, they are the same: the apparent power is equal to the real power. The relationship between real power (the average power above) and apparent power is described by the power factor.
