The way to choose Solar Street Light Controller

The main control part of the solar street light is the controller, belonging to the "central nervous system" of the solar street light, controlling the charging and discharging of the solar street light, the battery overshoot protection, and the protection of the solar street light system as a whole. So how to choose solar street light controller?

1.Choose the right current

The current of the solar street lamp is 5A, 10A, 15A, 20A, etc. The current of the selected controller must be correct, and the selected current should be larger than the maximum current needed. For example, if the system current is 2A or 3A, we can choose 5A current. The maximum current is 5A, we can not only choose 5A current, the best choice 10A, to prevent the current is too large and burn the controller.


2.Select the correct buck and boost features

If the controller has step-down or step-up function, we have to choose the right one, and set the solar street light manufacturers before leaving the factory.


3.Choose the right voltage

Solar street lamp system voltage is 12 volts or 24 volts, but also a small part of the 36 volts and 48 volts, solar street light controller selection, we must choose the right voltage, or can not work.


4.Sub-time adjustment of the power controller, the choice of matching constant current source

If you want street lighting to achieve sub-time control of brightness, you must select the matching of the constant current source, or impossible, different street controller on the constant current control requirements are not the same, so we must choose the right model .
