The inverter rating is in KVA because of in any active
components (like transformers, D.G, inverters etc..), the
power is calculating based on the output of the devices. At
the output terminals, no losses are considered causing by
active/passive loads (R,L,C). This is not depend on the
input.
But in the passive components (like motors, engine etc..),
the output is taking by means of input.
The output is always lesser than the input due to losses.
So the motors are denoted in the unit of KW.
