PWM solar controller refers to the use of the digital output of the microprocessor to control the analog circuit, which is a method of digitally encoding the analog signal level.
Our common street lights include solar street lights, city circuit lights, wind street lights and wind-solar hybrid street lights. And different street lights correspond to different controllers.
There are two main types of solar controllers (also known as solar charge controllers) on the market: MPPT solar controllers and PWM solar controllers.
There are many types of solar controllers on the market with different functions and functions. Each company does not have a unified manufacturing standard.
As a necessary component of the off-grid power generation system, the solar controller has more and more models and specifications of solar charge controllers, and the functions and characteristics are also different.
The photovoltaic system consists of the following three parts: solar panels, solar controllers, inverters, test instruments and computer monitoring and other
