VA to Amps Calculator
In power engineering, it is often necessary to convert apparent power (Volts-Amps, VA) to current (Amps, Amps) for circuit design, equipment sizing or troubleshooting. Our VA to Amps Calculator is designed to address this need with an easy-to-use, fast and accurate conversion.
Key Features:
- Single/Three-Phase Support: Whether your system is single-phase or three-phase, this calculator can handle it with ease, just choose from the βNumber of Phasesβ option.
- Real-time calculation: Enter the apparent power (VA) and voltage (V), click the βCalculateβ button, and you will get the current (A) result immediately.
Single phase VA to amps calculation formula
The current I in amps is equal to the apparent power S in volt-amps, divided by the voltage V in volts:
3 phase kVA to amps calculation formula
The current I in amps is equal to 1000 times the apparent power S in volt-amps, divided by the square root of 3 times the line to line voltage VL-LΒ in volts:
VA to Amp Calculator in Solar Energy
- Solar System Design:
When designing a solar power system, you need to determine the maximum output power of the system (usually measured in kilowatts) and calculate the amount of current required accordingly. With the VA to Amp calculator, the apparent power of the system (equivalent power after taking into account the power factor) can be quickly converted to a current value so that the right cables, inverters, batteries and other components can be selected. - Component Selection:
Individual components in a solar system, such as solar panels, inverters, batteries, etc., have their rated current and voltage parameters. With the VA to Amp calculator, you can calculate the current value required for each component based on the total apparent power of the system to ensure that the selected component can meet the operational requirements of the system. - Troubleshooting and Maintenance:
During the operation of a solar system, if there is a problem such as an abnormal current or power drop, the VA to Amp calculator can be used to quickly check the system's power parameters. By comparing the calculated current value with the rated current value of the module, the cause and location of the fault can be preliminarily determined so that appropriate maintenance measures can be taken.
