There are several solar street light controllers according to the charging method

There are many types of solar  light controller, ordinary split type controller, built-in boost constant current control integrated controller, built-in step-down constant current controller, plastic shell waterproof grade IP32 controller, waterproof grade IP68 Full waterproof street light controller. Today I will introduce to you in accordance with the charging mode, the solar controller can be divided into PWM type controller and MPPT type controller.

一: PWM type street light controller

Pulse Modulation (PWM) is a very efficient technique that uses the analog circuitry of a microprocessor's digital output for control. Charging is divided into three periods with a strong charge voltage of 14.8V, a balanced charge voltage of 14.5V, a float voltage of 13.7V , Effectively prevent battery overcharge, extend battery life.

二: MPPT type street lamp controller

The MPPT controller, also called the MPPT solar controller, is an upgrade of the PWM controller. The MPPT controller is capable of monitoring the voltage generated by a solar panel in real time and tracking the maximum charging value of the solar panel so as to maximize the system's power consumption. Efficiency Charges the battery. Up to 30% more efficient than PWM controller.
