The Inverter Cable Size Calculator is an essential tool that helps individuals or professionals determine the appropriate cable size required for inverters. It assists in calculating the cross-sectional area of the cable needed, ensuring optimal performance and safety in electrical systems.
Formula of Inverter Cable Size Calculator
The formula used by the Inverter Cable Size Calculator is:
Cable Size (in square millimeters) = (2 x I x L x K) / (V x √3)
This formula breaks down as follows:
- Cable Size: Represents the cross-sectional area of the cable in square millimeters (mm²).
- I (Current): Denotes the current in amperes (A) that the inverter will draw.
- L (Length): Indicates the cable length in meters (m) from the inverter to the load.
- K (Correction Factor): Represents a factor based on cable insulation and installation conditions, typically ranging from 1.0 to 1.25.
- V (Voltage): Signifies the operating voltage in volts (V) of the inverter, usually 230V or 120V for single-phase systems.
- √3: Represents the square root of 3, approximately 1.732 for three-phase systems.
Understanding these variables helps in calculating the appropriate cable size necessary for an efficient and safe inverter setup.
