Converting kVA (kilovolt-amperes) to VA (volt-amperes) or VA to kVA is a common task in day-to-day power engineering, electrical design, or any situation where you need to deal with power unit conversions. To simplify this process, we have developed this handy online conversion calculator.

The relationship between KVA (kilovolt-amperes) and VA (volt-amperes) is primarily reflected in the measure of power, which is a unit of power capacity, but of a different order of magnitude. Specifically, KVA is a thousand times VA, i.e., 1 KVA is equal to 1000 VA. Both units are used to express the apparent power of a power supply, i.e., the maximum power that a power supply can provide under certain conditions.

Apparent power is the product of voltage and current, denoted by S, in VA or KVA. it consists of both active and reactive power. active power is the power that actually does the work, while reactive power is the power that does not directly do the work in the circuit, in Var or kVar. Active power is the power that actually does work, in W or KW, while reactive power is the power that does not directly do work, such as generating a magnetic field in a circuit, in Var or kVar. apparent power is the vector sum of the two parts of the power, and is therefore usually larger than the active power.

In the field of solar energy, kVA to VA and VA to kVA conversion calculators have important applications

• Capacity Planning: In the design and planning phase of a solar power system, the capacity of the system needs to be accurately calculated. The direct current (DC) generated by the solar panels is converted to alternating current (AC) by an inverter, whose capacity is usually expressed in kVA. The use of kVA to VA and VA to kVA conversion calculators helps engineers to accurately calculate the required inverter capacity based on the expected power demand and the actual condition of the system, thus ensuring the stability and efficiency of the system.
• Power Generation Calculator: The amount of power generated by a solar system is usually expressed in kWh (kilowatt-hours), but in some cases it needs to be converted to kVAh (kilovolt-amperes-hours) or VAh (volt-amperes-hours) for evaluation. Using the VA to kVA Conversion Calculator, power generation can be converted into units that are easier to understand and compare, allowing for a more accurate assessment of system performance.
