Installation

1. The place where the controller is installed should be well ventilated, avoiding direct sunlight and high temperatures. Furthermore, water should not be able to reach the controller.
2. Please select the correct screws to attach the controller on the wall or on another platform. Use M4 or M5 screws, with a screw head diameter of less than 10mm.
3. Please leave enough space between the wall and the controller, to allow the controller to be well ventilated and to leave room for cable connection.
4. The distance between the mounting holes is 155,8 x 63,0 mm. The diameter of the holes is 5 mm.
5. Connect the components in the following order:
6. Connect the battery

  *  **Note:** the battery terminal should be installed with a fuse. The installation distance should not exceed 50mm.
2. Connect the load
3. Connect the solar panel array
4. The controller is now switched on

6. Note: if an inverter or other starter current is being connected to the system, please connect it directly to the battery. Do not connect the inverter with the load terminal of the controller.
7. While connecting the components to the controller in the sequence, please pay extra attention to connecting the ‘positive’ and ‘negative’ correctly. Don’t insert the fuse or turn on the breaker during the installation.
8. Always connect the battery first. This way the controller will be able to recognize the system voltage.
9. Install the battery fuse as close to the battery as possible.
10. The distance between the battery fuse and the battery group should be within 150 mm.
11. This controller is a positive grounding controller. Any positive connection of the solar load or the battery can be grounded at the same time, as required.
12. Before use, the terminals of the controller are in a fixed state. Please loosen the terminals, in order to connect the components correctly.
13. Please do not change the order in which the components should be connected, otherwise it will cause a system voltage recognition error.
14. The length of the cable between the controller and the battery should be as short as possible. A length of 30 to 100 cm is recommended.
15. It is strongly advised to connect a fuse at the battery side, 1.5 times the rated current of the controller. If a terminal short circuits, it could cause a fire or an explosion. Please be extra careful to avoid short circuiting.
16. If the battery gets a reverse connection, the output of the controller will get the same polarity as the battery. If this occurs, please do not connect any load to the controller, or the load and the controller will be damaged.
17. When the solar panel is in sunlight, its voltage is very high. High voltage can cause injury or destroy the controller. Make sure PVmax is under the required safety MPP range.
18. Before connecting the load to the controller, please turn off the output of the controller (using the button) first, to avoid injury from the load voltage. The controller does not offer reverse connection protection for load. Reverse connection concerning load will destroy the load, so please be careful when connecting.

Operation

Main interface

1. When the controller is turned on, it will show the initialization interface for 1 second, after this the main interface will appear.
2. If the main interface is not operated for 20 seconds, it will automatically rotate between showing the battery voltage, the solar panel voltage and the temperature of the environment. Each parameter will show for 3 seconds, before switching to the next. Press and hold the SET button at the main interface for more than 5 seconds to speed up the automatic rotation, release the button to return to the normal speed.
3. When in the main interface, press the SET button to turn the output on or off.
4. Press the MENU button to switch to the next interface. The order of the interface is the following: Main interface – Float voltage – Load reconnect voltage – Load disconnect voltage – Load mode – System voltage select – Main interface.
5. Float voltage setup; High Voltage Disconnection (HVD):
   • This parameter stands for the HVD voltage. In the main interface, press the MENU button to go to the float voltage interface. Now, press the MENU button for more than 5 seconds, until the numbers start flashing. Use the SET and MENU buttons to adjust the parameter making it lower (SET) or higher (MENU). When the adjustment is finished, press the MENU button again for more than 5 seconds, until the numbers stop flashing. The adjustment is now saved. If there is no further action for 20 seconds, the interface will switch back to the main interface.
6. Low Voltage Reconnection (LVR) voltage:
   • When the battery voltage is low, the controller will stop the output to the load. When the output needs to be turned on again, the battery voltage must be higher than the LVD voltage, or press the SET button to force a release. The process of adjusting the parameter with the SET and MENU button is the same as described above at point 5.
7. Low Voltage Disconnection (LVD) voltage:
   • When the battery voltage is low, the load output will be turned off. If the controller detects that the battery voltage is lower than the LVD voltage, the output will be immediately turned off. The status of the controller is now locked as well. The battery has to be charged. To turn the load output back on, the battery voltage must be higher than the LVD voltage, or press the SET button to force a release. The process of adjusting the parameter with the SET and MENU button is the same as described above at point 5.
   • Note: Generally users don’t need to adjust. Before making adjustments, please refer to the recommendations of the battery’s supplier, or the battery might be (irreparably) damaged.
8. Selecting the load working mode:
   • By default the operating hours of the load will be set to 24h. When set at 24h, the load will keep operating all 24 hours, when there is no error.
   • When set to less than 23 hours, the timer or sensor function will be activated. The load will turn on at sunset. The load will turn off at sunrise, or at the hour at which the timer has been set.
9. Selecting the system voltage:
   • The default mode is ‘UTO’, a system voltage of 12/24V. When the battery voltage is more than 18V, the controller will automatically change to 24V. When the battery voltage is less than 18V, the controller will automatically change to 12V.
   • If the system voltage is set to mode ‘1’, the controller will keep the voltage under 12V. This will take effect after reconnecting the battery.
   • If the system voltage is set to mode ‘2’, the controller will keep the voltage under 24V. This will take effect after reconnecting the battery.

Protection

1. Battery: Low Voltage Disconnection (LVD):
   • The LVD is activated, when the battery voltage is less than 11V. The output is turned off. Also, the battery symbol will be flashing as a warning. Please increase the charge current or increase the charging period.
   • The LVD will be deactivated, when the battery voltage is more than 12.6V. The load output will now be turned back on, or can be forced back on by pressing the MENU button in the main interface.
2. Battery: Over Voltage Disconnection (OVD):
   • The OVD is activated, when the battery voltage is more than 16.5V. The load will be turned off. Also, the load and warning symbol will be flashing.
   • The OVD will deactivate, when the battery voltage has decreased to 15V. The load output will be turned back on.
3. Load: Over Current Protection (OCP):
4. When the load has short circuited or overloaded, the output is turned off. Also, the load and waring symbol will be flashing. Please check if there is a short circuit on the load terminal and decrease the power of the load. After 30 seconds, the controller will automatically restart when the output is turned on, or press the MENU button in the main interface to turn it back on.
5. High Voltage Disconnection (HVD) protection:
   • The HVD will be activated, when the battery has been charged to 13.8V. The charge symbol will be flashing and the battery voltage will be limited.

Troubleshooting

1. The solar panel is disconnected:
   • Check if the solar panel input is connected correctly and whether the contact is reliable.
2. The battery voltage is less than 8V:
   • Check the battery voltage. The controller will only start when the battery voltage is more than 8V.
3. The solar panel voltage is less than the battery voltage:
   • The voltage of the solar panel must be higher than that of the battery.
4. Battery over discharge:
   • The load output is turned off automatically and recovers when the battery capacity is high enough.
5. Battery over voltage:
   • When battery over voltage occurs, please check if the battery voltage exceeds the needed volage and afterwards reconnect the solar panel.
6. Overload:
   • Reduce load or check the connection of the load.
7. Over temperature:
   • Make sure the controller cools down. Afterwards charging should restart automatically.
8. The charging current of the solar panel is too high:
   • Check the output of the solar panel and reduce de amount of parallel connected solar panels. Restart after 2 minutes.
9. The display shows LVD:
   • The battery is over discharged. Check whether the system set-up is feasible or not; whether there is more discharging capacity than charging capacity.
10. The display shows HVD:
    • The battery voltage is too high. Cut off he solar panel and check if the voltage goes down to a normal level. If the error does not go away afterwards, disconnect the battery and reconnect it again.
11. The display shows OCP:
    • The load has short circuited or overloaded. Check whether the cables of the load have short-circuited, whether the output of the load is too high, or the surge power of the load is too high.
