Design And Working Process Of Solar Controller

The solar controller is designed to do two things inside the main solar power generation system: optimize your charging deep cycle battery by the solar panel, and block the current from the battery, from experiencing the solar panel when there is no sunscreen.

It includes the function of automatically turning on or off DC powered loads (such as lamps). Others can be used with solar panel strings with relatively high voltage. In addition, some can monitor the battery voltage and remaining ampere hours, and even connect to the home data network for remote monitoring.

The solar controller is specified by amperage and voltage. You will need a battery that can support the voltage of the solar panel array, and then output it to the voltage of the battery pack (usually 12, 24, or 48VDC). Next, you will make sure that the solar controller has enough capacity to handle the current (in amperes) from the solar panel array. Divide the wattage of the solar panel by the voltage of the battery pack to roughly estimate how many amperes the controller needs.

Ensure that this important part of the system is protected by appropriate overcurrent protection before and after the solar controller (for options, see chassis, electrical and safety).
