PWM Solar Charge Controller Auto Switch 12V/24V 20A Auto Light Control For Street Light And Solar Lighting For Home   

 

Main features

1. For mini solar power station syste; for street light;2. Five load working modes: Pure lighting control, lighting control & timing control, hand operation and test mode and load open all time.3.And have temperature compensation function.4. The storage battery is charged every 7 days to prevent the battery from Vulcanization, also extended service life of the storage battery.5. Have the electricity protection data function.6. Charging circuit is adopt the dual MOS Series control loop, decrease loosing of the loop volt. adopt the PEM mode to control the charging to increase the charge rate.7. The state of solar battery, storage battery and load is showed on the LED. Regulate parameters is showed on digital tube. Customer can setting the working mode according to the environment and observe the operation status.8. Over charging protection, over discharging protection, over load, short circuit protection, reverse polarity protection and TVS lightning protection.9. All the controllers adopt Industrial chip and precision components, which can operate normally under the cold, heat and humid environment.10. Digital LED display and one button setup make the device easy to handle.
