Solar Panel Controller Input Voltage

Preventing the battery from overcharging is important merely because the voltage generated by even a 12v solar panel is actually higher between 16 and 20v.

Solar panel controller input voltage.

With mppt controllers the current is drawn out of the panel at the maximum power voltage but they also limit their output to ensure batteries don t get overcharged. It regulates the voltage and current coming from the solar panels going to the battery. The solar panels input voltage of the mppt solar controller is generally about 0 150v and the input voltage of the pwm solar controller is generally 0 55v. A solar charge controller also known as charge regulator or solar battery maintainer is a device that manages the charging and discharging of the solar battery bank in a solar panel system.

Even though the voltage from the solar module could be at 17vdc and the charge controller would be charging at 14v while the inverter was running happily at 13vdc input the whole system was made up of 12v nominal components so that it would all work together. As long as the voltage is under these values the right mppt controller is easy to find. Mppt charge controllers will monitor and adjust their input to regulate the current from your solar system. A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging.
