Question:

What is the maximum cable size that can be used between the solar panels and the solar controller?

Answer:

Various factors, such as the distance between the solar panels and the solar controller, the current capacity of the panels, and the limitations on voltage drop, influence the maximum cable size that can be used. It is generally recommended to use larger cable sizes to minimize voltage drop and ensure efficient power transmission. To determine the maximum cable size, one must consider the cable's current carrying capacity and the voltage drop over the distance. The manufacturer typically defines the current carrying capacity, which can be found in the cable specifications. It is crucial to select a cable capable of handling the maximum current generated by the solar panels. Voltage drop is another crucial factor to consider. It occurs due to the cable's resistance and can impact the overall performance and efficiency of the solar system. The acceptable voltage drop varies depending on the system's requirements, but a general guideline is to keep it below 3% for optimal performance. To calculate the maximum cable size, one can use the voltage drop formula and the cable's current capacity. By considering the distance between the panels and the controller, the current generated by the panels, and the acceptable voltage drop, one can determine the appropriate cable size. For specific solar panels and controllers, it is advisable to consult with a professional or refer to the manufacturer's guidelines. They can provide accurate recommendations based on the system's requirements and ensure the optimal cable size is chosen for maximum performance and safety.
