The Difference Between Solar Charge Controller MPPT and PWM 2018-06-05 09:01:19

Solar charge ontrollers have a variety of appearances on the market, and the types are also various. Here I will introduce to you the difference between PWM and MPPT solar charge controller.


The difference between PWM and MPPT refers to the different charging methods of solar charge and discharge controllers. PWM is the abbreviation of “Pulse Width Modulation” in English. It is referred to as pulse width modulation. It uses the digital output of a microprocessor to control analog circuits,which is a very effective technique.


MPPT means that the controller can detect the voltage of the solar panel in real time and track the highest voltage and current (VI) so that the system can charge the battery with maximum power output.


Different charging methods result in completely different circuit designs and the cost varies greatly. If someone says that he is an MPPT controller and the price is the same as the price of PWM, then there must be a problem.


Anhui JNGE Power Co.,Ltd. can do 30A to 100A solar charge controller, and the voltage is 12V/24V/48V Auto, have been widely selling to North-American and European market, its your best PV supplier in China.
