LED 12 volt 20 amp solar charge controller hight quality and low price

  LED 12 volt 20 amp solar charge controller hight  quality and low price 

Main features:
 
1. Intelligent control is realized by using microprocessor and dedicated control calculation.
2. Four load working modes: Pure lighting control, lighting control & timing control, hand operation and debug mode.
3. Scientific management of battery: as it is overcharged, the battery will get booster tension charge. 

4. Comparing with the charging loops using diodes, the one that adopts double MOS series circuit control makes the voltage loss dropped by 50%. With the PWM fuzzy control in charging, the charge efficiency is improved a lot.

5. LED screen shows the working state of solar battery, storage battery and load. 

All the protections are harmless to any parts and fuse. TVS thunder proof protection is also available. Non wire jumpers design improves the reliability and durability of the products.

6. Various protections include: over-charge, over-discharge and over-load, as well as unique electron short circuit protection and connection-reverse protection

7. Technical grade chips and precision components are adopted for all the controls. 

8. Digital LED display and one button setup make the device easy to handle.

9. Discharge rate revision controls: Different discharge rate matches with different cut-off voltage, which is in        compliance characters of storage battery.
