A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps. On the other hand, a watt (W) is a measurement of real power. Real power is the amount of actual power that can be drawn from a circuit. When the voltage and current of a circuit coincide, the real power is equal to the apparent

Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert

In your case, there are two important parameters for a UPS. Power (kVA) and Energy (VAh). Power is a measure of how much instantaneous power the UPS can source. This is important based on how much power the attached devices need to draw. Energy is important because it dictates how long the UPS can continue to run.

Apparent power. Apparent power is the actual amount of power drawn from the source. It includes both true power and reactive power. Apparent power is denoted as S. In the case of DC, the apparent power is irrelevant. But when it comes to AC, for reactive loads, the current and voltage are out of phase.
