. Product Overview
1. Use single-chip microcomputer control which makes the controller has the advantages of intelligent, strong adaptability, reliable function.
2. Use PWM charge mode, which can improve system efficiency and prolong the life span of the battery.
3. Clear charge state, discharge state and battery power display.
4. Adopts the modified shell which accords with air flow, has better cooling effect (compare with the old version).
5. Optimize the assembly design, the structure more stable.

. Protection
1. Over-load protection
2. Short circuit protection
3. Lightning protection
4. Under-voltage protection
5. Over-charging protection
6. Reverse polarity protection

.LCD display
A.Charge: the left arrow display, when the left arrow flickers, it means the solar panel is charging, the battery is in the state of full charge or float charge.

B.Discharge: when the load output switch is ON, the right arrow display, it is allowed to discharge. When the controller has discharge current, the right arrow flickers.

C.Failure interface: when short circuit or over load occurs, the failure interface appears. At this time, you can press the load output switch to close the output or just wait. After finish trouble shooting, the output recovers automatically. If short circuit lasts over 30s, the controller automatically close the output.

D.Load output switch: the output switch default open, when the interface appears LOAD or the right arrow, the load output of the controller is permitted. When the battery is under voltage, the output stop, the output switch could not work. Only when the battery voltage returns to Normal, the output switch can be operated.
