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.
Solar panel controller input voltage.
Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging.
Mppt charge controllers will monitor and adjust their input to regulate the current from your solar system.
In case of special requirements if these input voltages are higher than the rated values it s.
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 charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging.
It regulates the voltage and current coming from the solar panels going to the battery.
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.
