Product overview
1. Use single-chip microcomputer control which makes the controller has the advantages of intelligent, strong adaptability, reliable function.
2. Use Ueiua PWM upgrade control scheme WPC mode, which can improve system efficiency and prolong the life span of the battery.
3. With intuitive digital tube to show the current battery state, it is convenient for the user to know the working condition of the controller.

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

Installation Instructions
Open the top cover of controller and connect the wire with terminals as the diagram on the top cover of it.
1.Connect the +, - Poles of the battery to the corresponding ports of controller (the third and the fourth one from left).
2.Connect the +, - poles of the solar panel to the corresponding ports of controller (the first and the second one from left).
3. Connect the +, - poles of the load to the corresponding ports of controller (the fifth and the sixth one from left).

Note: If there is connection error, it may damage your controller.


Status instructions
The charge indicator: While charging, the charge indicator will be green light ON. When the battery indicator is flashing uninterruptedly, it means the battery is full charge and the system enters into intelligent protective charging.
Battery voltage display screen: the battery voltage will display only when the battery power is normal.
Battery under voltage display: when the battery is in the state of under voltage, (in the 12V system the battery voltage is less than 12V, in the 24V system the battery voltage is less than 20V, a middle cross of the digital tube flickers as it shows in the figure.
