Solar street lamps controller design specification

System by the solar panels solar street lamps, the LED street lamp controller, lead-acid battery and LED street lamp module. Throughout the system, solar street lamp controller in the core position, the work is good or bad directly determine the performance of the whole system. The

system consists of solar panels, solar street lamps led street lamp controller, lead-acid battery and led street lamp module.

in the whole system, solar street lamps controller in the core position, its work directly determine the performance of the whole system. Controller with multiple protection function, such as battery overcharge, discharge protection, solar battery over-voltage protection, load short circuit protection, etc.

controller according to the design requirements, at the beginning of charging according to state of battery charging mode, if the battery is in over discharge condition, to improve charging mode; If the battery is in a state of undervoltage, into direct charging mode; If the battery in a floating state, it will turn into float mode, if the battery itself overpressure, it will continue to keep the overpressure alarm status. As ascension or direct charging is complete, switch controller to float charging status, when the battery voltage due to the load power consumption dropped to direct charging return point, the controller switch to direct charging status again.

at this point, if the load continues to use electricity, the charging energy and solar panels are not enough, lead to the battery voltage to drop to under voltage and over discharge points, solar street lamps controller into the over discharge protection, shut down the load and into the high charging status.

in practice, people often hope to reduce the brightness in the middle of the night lights, and solar street lamps controller can do it.

the purpose of this method is to save energy, the second is to extend the service life of the solar street lamps, keep the same color temperature under different brightness. Old street lamp without power control or dimming function.

as a result, this method can achieve this goal.
