Solar street light controller buck-boost comparison solar street light

What is the difference between the step-down type and the step-up type of solar street light controller: These two controllers are a combination of solar controller and LED light source driver, both of which are suitable for the case that the LED light source is not driven , The boost type is to raise the low voltage 12V or 24V to 40~50V through the DC~DC circuit, which is suitable for modules with about 10 strings of LED solar street light beads. The characteristics of this model are that the voltage is high and the current is small; The step-down type is to reduce the voltage through the DC~DC circuit, from 12V to about 10V. The characteristics of this model are that the voltage is low and the current is large. The quality of the step-down and step-up controllers varies from manufacturer to manufacturer. The choice of which type of controller is only guaranteed by a professional solar lighting manufacturer of a big brand.
