SMR20-N5 is a sort of ip68 solar controller.

It means 12V/24V automatic recognition as well as 20A charge and discharge current.

More and more solar street light are widely used in city lighting.Not only PWM LED light solar controller,but also MPPT LED light solar controller are both very popular in the market.In these two years,our waterproof MPPT solar charge controller are sold more and more in the International market.But in domestic,most customers still perfer to choose PWM,because many projects depend on allocating funds by government to finish the whole progress,they perfer low cost and they use lithium battery instead of lead acid battery.

How to design a good lighting system? You must consider comprehensive aspects.One customer want to use two lights to connect one controller.In theory,it is implementable.He set light operation current by remote,while he found the intensity is not the same.Why did happen this phenomenon? The internal resistance in the lights are different,so the LEDs got the different current.It is impossible to get average.You could not gurantee their intensity is completely the same.Sometims,small differece,you couldn’t find,but sometime,it is obviously. In this situation,we suggest cusomter to seprate two systems,each controller connect one panel,battery and one lights.Although it cost more,it will reach your want resault.
