Calculate Inverter Cable Size







Formula

The formula to calculate the Inverter Cable Size (CS) is:

\[ CS = \left( \frac{P}{V \cdot E} \right) \cdot L \]

What is Inverter Cable Size?

The inverter cable size refers to the thickness and length of the cable used to connect an inverter to a battery or a power source. The size of the cable is crucial as it affects the efficiency and performance of the inverter. A cable that is too thin or too long may result in power loss due to resistance, while a cable that is too thick may be unnecessarily expensive and difficult to install. The appropriate cable size depends on the power output of the inverter and the distance from the power source.

Example Calculation

Let's assume the following values:

Using the formula:

\[ CS = \left( \frac{1500}{12 \cdot 0.9} \right) \cdot 5 = \left( \frac{1500}{10.8} \right) \cdot 5 \approx 138.89 \text{ square millimeters} \]

The Cable Size (CS) is approximately 138.89 square millimeters.
