Information

Both PWM and MPPT controllers have their own unique advantages and disadvantages. Which one to choose depends on the design characteristics, cost, and external environment of the solar photovoltaic array. When we choose to focus on the following factors:

quality pwm solar controller

PWM mode technology is mature, the circuit is simple and reliable, and the price is cheap, but the utilization rate of components is low. The utilization rate of the module is about 80% or more; the MPPT solar controller refers to the solar controller with the maximum power point tracking function. There is a buck step-down circuit between the module and the battery, and the utilization rate of the module is about 90% or more.
 The main users of small off-grid systems below 2kW are poor areas without electricity, such as remote mountainous areas and some poor countries in Africa, mainly to meet the needs of lighting, and users are very sensitive to prices, so it is recommended to use PWM controllers to correct the wave Inverter, the controller, inverter and battery are integrated.
 For off-grid systems above 2kW, it is recommended to use the MPPT controller, which has high component utilization, high overall machine efficiency, and flexible component configuration. In general, no single technology is the best, so users should take the advice of the experts to make sure they choose the right controller for their needs.
