Xindun best Price K1 series micro smart solar controller 5A 10A 15A 20A 30A 40A 50A for solar light system
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
4. Comparing with 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. LED shows the adjusted
parameter. In this way, users can learn the operation state in ream time. Besides, there are various
choices for parameters; users can select the proper working mode based on the different conditions.
6. Various protections include overcharge, over discharge and overload as well as unique electron short
circuit protection and connection reverse protection.
7. Technical grade chips and precision components are adopted for all the controllers.
8. Digital LED display and one button setup make the device easy to handle.
