This solar charge controller is suitable for both private and industrial use, as well as for telecommunications systems. The load can be activated by the user based on various configurations: load always on, load only activated during the day, load only activated at night, or load only activated at night with a programming function for a total period of 1 to 16 hours. The charge controller determines day/night conditions based on the module voltage, so there is no need to connect additional sensors to the controller.
