In general, it is recommended that the voltage drop between the solar panels and the charge controller does not exceed 3%. Now, there are probably going to be 2 types of wires connecting your solar panels to your solar charge controller: PV or USE-2 type wires connecting your solar panels to the combiner box or pass-through box.
To size the wires between your solar panels and solar charge controller correctly, you’ll need to make sure that the ampacity of each wire is at least 1.25 greater than the maximum current going through the wire, and that the total voltage drop between your solar panels and solar charge controller does not exceed 3%.
If your solar system has a 50A output capacity but the controller is only 30 amps, only 30 amps goes into the system. The rest is wasted. There is no risk of overcharging the controller. The controller is going to restrict the output to what it can handle. However it is going to result in a lot of energy loss.
Proper management of photovoltaic cables includes using metal clips to keep them attached to the panel, preventing them from bending out of shape and causing short circuits. Using high-quality materials is essential to minimize the overall expenses in the long run. Cable management also involves the placement of the cables.
Understanding line loss is crucial when setting up your solar power system. When electricity flows through a wire, some of it gets lost along the way, impacting the efficiency of your solar system. This loss is influenced by the length and thickness of the wire, as well as the amount of current flowing through it.
If the controller is not big enough, your system will not function at its optimum level. Keep in mind that a 12V solar panel can go up to 18V when running, and a 24V panel may reach 36V. 12V and 24V are nominal voltages, but their actual voltage when running is higher. That is another reason why we add 25% to the controller size calculation.
The Ultimate Guide To Solar Panel Wires & Cables
Solar cables combine several insulated wires enveloped by a protective outer jacket. They can handle high UV radiation, extreme weather conditions, and high temperatures. The three common types of cables in the solar power system include DC solar cables, solar AC connection cables, and solar DC main cables. DC Solar Cable

What size wire from solar panel to charge controller?
In other words, the size of the wire must meet 2 conditions: Condition 1: The Ampacity of the wire must be at least 125% greater than the Maximum Current. Condition 2: The wire must be thick enough to limit the voltage drop between the solar panels and the solar charge controller to 3%. Let me explain each of these separately. 1- Determining wire Ampacity based …
