How to Use

To utilize the inverter cable size calculator, follow these steps:

  1. Input the required information, such as the inverter voltage, maximum current, and cable length.
  2. Click the “Calculate” button to generate the recommended cable size.
  3. Review the result provided to determine the appropriate cable gauge for your application.


The formula used for calculating the cable size is based on the following considerations:

Example Solve

Suppose we have an inverter with a voltage of 12V, a maximum current of 100A, and a cable length of 10 meters. Using the formula:

Rounding up to the nearest standard cable size, we recommend using AWG 46 cable.


Q: Can I use this calculator for both DC and AC inverters?
A: Yes, the calculator is suitable for both DC and AC inverter applications.

Q: What is the significance of the voltage drop in cable sizing?
A: Voltage drop refers to the reduction in voltage along the length of the cable due to its resistance. It is essential to limit voltage drop to ensure the proper functioning of electrical equipment.

Q: Are there any safety considerations when selecting cable size?
A: Yes, always ensure that the selected cable size can handle the maximum current without overheating, which could lead to fire hazards.


The inverter cable size calculator provides a convenient tool for accurately determining the appropriate cable gauge for your specific inverter setup. By inputting essential parameters and utilizing the provided formula, users can ensure safe and efficient electrical installations.
