Solar controller as control unit, solar led street lamp in solar led street lamp system plays an irreplaceable role, is like the human brain or the computer's processor, although he is small in size, but have the effect of the core, so it is particularly important to choose a quality controller. Quality controller should be able to make each customer can according to the solar street light configuration to set up out of the voltage protection. But it is worth noting that the panel configuration must be reasonable, if the amount of charging panels daily discharge can't meet that night, in the long term, often in a deep discharge, battery life shortens greatly, so the configuration of led solar street light panels must enlarge allowance, configuration of panels, the greater the exit to protect the low voltage can be set up, it won't cause the impact on the battery. Solar led street lamp is very suitable for pulse width adjustment to achieve different power output. Control of pulse width or limit current at the same time, the duty cycle of LED lights the whole output adjustment, such as single atom 1 w LED string of 5 and 6 combined 30 w leds, discharge at night, late at night and early in the morning time can be separately power regulation, such as the middle of the night to adjust into 15 w, adjust into 24 w, in the morning and lock current, which can satisfy all night lighting, and saving the cost of the panels, battery configuration.
