Control Principle Of Solar Lawn Lamp

Solar lawn lamp controller is mainly used for battery charging and discharging control. As shown in the charge controller schematic, photovoltaic solar panels, batteries, solar controllers and load a basic PV applications. Here switch K1 and K3 is charging switch, K3 for the switch, which is part of the Center for solar energy control. Switch opening and closing in the figure decided by the charge and discharge control circuit according to the State. When the battery is fully charged, disconnect the charging switch, need to be closed when charging charging switch closed when the battery discharge K2, or disconnected. And these control circuits using transistors, resistors, capacitors, inductors, consisting of charging and discharging voltage boost circuit, or light control circuit, or composed by integrated operational amplifier voltage hysteresis comparator, SCM can be used. Given the cheap considering the generally used the former.
