Solar street lamps controller should use step-up or step-down?

New rural construction project in our country has entered the final stage, many rural areas are already installed solar street light. But there are so many people heart question: why do some manufacturer of solar street lamps using solar controller is a booster, there are

the new rural construction projects in our country has entered the final stage, many rural areas are already installed solar street light. But there are so many people heart question: & other; Why do some manufacturer of solar street lamps use solar controller is a booster, while others use step-down controller, what difference between them? ” 。 With this question, then let small make up tell you what's the difference between them.

a booster, solar street lamp controller

solar boost controller usually adopt the way of ten series and more connections, can be directly to the 12 v or 24 v low voltage up to 40 v - Around 50 v, and its high voltage but the current is relatively low. We want to know the general booster solar street lamps controller input voltage of 12 v / 24 v, and the input voltage 40 v - 50 v, this kind of controller is the booster. Remember to booster solar street lamps controller input voltage is less than the output voltage can be.

2, step-down controller for solar street lamps

solar step-down controller with three series of more general and the way of connection, it is through the specific circuit will be reduced to 12 v / 24 v voltage and power of 30 w, its characteristics and pressure controller, on the other hand, generally is low voltage, electric current is relatively large. We can see through the parameter tag step-down controller input voltage of 12 v / 24 v, output voltage is lower than the input voltage, so this is the step-down controller for solar street lamps.

in short booster solar street lamps controller input voltage is less than the output voltage, and solar street lamps step-down controller input voltage is greater than the output voltage, and they have different way of connection and power, these are the differences between them. Through small make up the above introduction, we can also learn to discern the solar street light lifting pressure controller, hope to be able to help you choose the solar controller.
