Thank you very much for selecting our product! This manual offers product overview, protection, installation instruction, status instructions, troubleshooting and technical data etc. Please read this manual carefully before using the product.
1. With LCD to display all parameters, the LCD has rich contents, the users can intuitively know the working condition of the controller.
2. With built-in energy-saving backlight LCD, display better and more power-efficient.
3. With SMPS DC12V and USB 5V stabilized voltage output, available for DC lamp and phone charging.
4. With output switch, intelligent control, easy to operate;
5. The system power adopts switching mode power supply which can reduce the quiescent current.
5. With separated temperature detected circuit, with high precision temperature compensation function.
7. With exposed terminals, the wiring more convenient, what’s more, the CMF series with metal shell.
8. Use single-chip microcomputer control which makes the controller has the advantages of intelligent, strong adaptability, reliable function.
9. Use PWM upgrade control scheme to WPC mode, which can improve system efficiency and prolong the life span of the battery.
| 1. Over-load protection | 2. Short circuit protection |
| 3. Lightning protection | 4. Under-voltage protection |
| 5. Over-charging protection | 6. Reverse Polarity Protection |
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
| ① Solar status display (day night display) | ② Charge current display |
| ③ Battery voltage display | ④ Output current display |
| ⑤ Environmental temperature display | ⑥ Warning – error display |
| ⑦ Warning – over heated protection | ⑧ Warning – over current protection |
The charge display:
During the day the LCD displays the sun, while charging it displays the charge current directly.
While at night it displays the moon and the charge current parameter will disappear.
Battery voltage display: always display the current battery voltage
Battery under voltage display: when the battery is in the state of under voltage, (in the 12V system the battery voltage is less than 10V, in the 24V system the battery voltage is less than 20V), at this time the load output is not allowed and the output current will displays “OFF”.
The load display:（the default output switch is open）
1. In the 12V system, when the battery voltage is less than 10.5V, the output current displays “OFF”, at this time the load output is not allowed. When the battery voltage returns to 12V, the load output restart and displays the output current.
2. In the 24Vsystem, when the battery voltage is less than 21V, the output current displays “OFF”, at this time the load output is not allowed. When the battery voltage returns to 24V, the load output restart and displays the output current.
3. When the load output overload or short circuit occurs, the controller will start the protect function automatically, and then turn off the load output, it displays “OC” and “ERROR”. The output protection will automatically try to recover after 10s, if the short circuit has been removed, the load output will start to work and displays the output current.
When the following phenomenon happens, please check as follows
| Phenomenon | Trouble shooting |
| The LCD cannot display | Check the battery wiring whether is well connected or whether the voltage of the battery is normal or not. |
| When there is adequate sunshine, it displays | Check the PV and battery wire whether is well connected or tight connection or not. |
| The charge current is quite low or the charge current keep flashing |
1. The battery is full charged and the system enters into protective charging. 2. The sunshine of the solar panel is insufficient. |
| The output current displays , the load cannot start |
1. Reference to the system wiring diagram, check the system whether is well connected or not. 2. Check the power of the battery, the load will start only when the battery voltage is Normal. 3. Connect the solar module, charge the battery until it reach to the normal state. |
| The image and flickers, the output current displays the output terminal without voltage | When in the state of over current or short circuit protection, the controller will return to work automatically after finish trouble shooting for 10 seconds. |
| Other phenomena | Check the wiring whether is tight or not, and the automatic identification of 12V/24V system is correct or not. |
Note: We keep right to change and update without prior notice.
