Two Varieties Of The Solar Street Light Are Distinguished By Charging Way 2017-11-09 10:24:43

Solar street light controller has many types, there are common type of split controller, built-in boost constant current control integrated controller, built-in buck constant current control integrated controller, there are plastic shell waterproof class IP32 controller, waterproof class IP68 Full waterproof street light controller. Today I will tell you about the way by charging, solar controller can be divided into PWM type controller and MPPT type controller.

1.PWM type street light controller

Pulse modulation (PWM) is a very effective technology to control the digital output analog circuit of the microprocessor. The charging is divided into three periods, strong charging voltage 14.8V, balanced charging voltage 14.5V, floating voltage 13.7V , Effectively prevent the battery overcharge, extend the battery life.

2.MPPT type street light controller

MPPT controller is also called the maximum power point tracking point solar controller, is the PWM controller upgrade products, the maximum power tracking point is the controller can real-time monitoring of the solar panel power generation voltage, and tracking the solar panel maximum charge value, making the system to the highest Efficiency to charge the battery. Than the PWM controller efficiency can be increased by up to 30%.
