What does parallel wiring mean?
In parallel connection, the positive and negative wires are bundled at one output. Through this circuit, the current increases and the voltage remains the same.
Practical example: You want to connect 3 pieces of 100w (Imp=5,56A Vmp=17,8V) solar modules to a charge controller with 20a and a max. input voltage of 30v/dc. In order not to exceed the allowed input voltage, you must wire the modules in parallel. So plus to plus and minus to minus.
If you now measure the string, you should be able to measure the following values under ideal lighting conditions: Imp=16.68A and Vmp=17.8V. So your solar configuration fits perfectly to the charge controller.
