What are the difference between solar street lamps controller step-down and booster?

1. Street light from a source to introduce different controller using different light source. Buck controller in three main series and parallel under the conditions of use. Booster controller used for a dozen, 33 v output voltage. Under normal circumstances, the product of the electricity of subsection

1. From the light source

introduce different controller using different light source. Buck controller in three main series and parallel under the conditions of use. Booster controller used for a dozen, 33 v output voltage. Under normal circumstances, the product of the voltage is divided into 12 v and 24 v, so we must choose according to their own conditions, LED street light, in this way can effectively reduce the cost. If the battery capacity is less than 100 AH, is the most. The good thing is to use a single 12 v system. Buck's maximum output power of 30 w, the maximum output power of the booster to 60 w.

　　2. From the view of the current

we talking about here is actually the charging current, street lamp is introduced because there are many different kinds of solar panels, and the intensity of illumination is very different also, leading to different charging speed. If the sun is very sufficient, the charging current will be very big. Controller manufacturers not only many, but the type is different also, so have different maximum current Settings, such as 5 a and 10 a. If the power of 100 w solar panels or higher, the output current is about 5. 8A。 At this time, if you use the maximum output current is 5 a controller, it will be a capacitive. The controller is easy to damage.
