PWM Solar charge controller (PPL Series)

PPL series PWM solar charge controller is a zero drop microprocessor based device with DC load terminals. It is a low cost solar charge controller for battery charging using solar power and for running DC loads such as DC fans, DC LED light, etc. The DC load can supply 20A of load current at battery voltage. If battery voltage is gets too low, then the DC load is shut down to protect battery from deep discharging. Once battery voltage becomes sufficient to run DC load, the load is switched on automatically. There is also a jumper setting on the product to run DC load only from dusk to dawn. This feature makes PWM-PPL series suitable for use in solar street light applications where high battery charging current is required.
