System Wiring

1. The positive and negative poles of the battery must be connected to the battery terminals of the controller first.
2. Connect the positive and negative poles of the solar panel to the PV terminals of the controller.
3. Make sure that the Bluetooth of the mobile phone is turned on, and open the APP “ChargePro 2.0” to enter the setting interface.

Note: Please strictly follow the above sequence for connection, otherwise the controller may be damaged. The disassembly sequence is opposite to the wiring one.
Caution

1. First make sure your battery system is 12V / 24V/36V/48V. (Lead-acid batteries can automatically identify the battery voltage, if you use lithium batteries, you must manually adjust the voltage to ensure that the battery voltage is consistent with the system voltage)
2.  Ensure that the maximum open-circuit voltage of the solar system does not exceed 150V.
3. Ensure that the maximum output current of the solar panel does not exceed 40A.
4. Ensure that the voltage of the solar panel is higher than the battery voltage

lead-acid Battery Working Stage

1. Lead-acid Battery Working Stage
2. CDBulk Charge: Constant current charging, providing the maximum current to the battery until the battery voltage reaches the constant voltage stage (boost charging voltage or equalize charging voltage).
3. Boost Charge: Constant voltage charging, the battery is charged for 120 minutes at an elevated charging voltage.
4. Float Charge: After the boost charge, the controller will reduce the battery voltage by reducing the charging current, and let the battery voltage be maintained at the set value of the floating charge voltage. During the floating charge stage, the battery is charged very weakly to ensure that the battery is maintained in a fully charged state. In the floating charge stage, the load can obtain nearly all solar power. If the load exceeds the power that solar energy can provide, the controller will not be able to maintain the battery voltage at the floating charge stage. When the battery voltage is low to the set value of boost charge return voltage, the system will exit the floating charging stage and enter the bulk charging stage again.
5. Equalization: Equalization charging raises the battery voltage to higher than the standard supplementary voltage to charge the battery. Certain types of lead-acid batteries benefit from regular equalization charging, which can agitate the electrolyte, balance the battery voltage, complete a chemical reaction, and prevent battery vulcanization.
   Note: Only FLD, SLD and ACM can perform equalization charging. The equalization charge will be carried out every 30 days, and the charge time is 120 minutes. When the battery is charged in equalization, the boost charge stage will not be performed.

lithium Battery Working Stage

1. CDBulk Charge: Constant current charging, providing the maximum current to the battery until the battery reaches the boost charge voltage.
2. Boost Charge: Charge with a constant current. When it is about to be fully charged, the charging current begins to drop, and finally charges with a small current. During this process, the charging voltage is constant to maintain the boost charge voltage.

FAQ

What information should I provide with BougeRV to get technical support faster and better?
Send the following information to the email: service@bougerv.com, CDThe connection method of the solar panels (series/parallel, quantity, voltage, power).

1. The voltage and battery type of the battery.
2. The display data of the controller: battery voltage, battery charging current, the output voltage of the solar panel.
3. Connection from solar panel to controller and controller to the solar panel.
4. If the above information can be provided with pictures or videos, BougeRV can provide you with technical support faster.

Why is the battery not charging after I connected the solar panel?
There may be the following reasons: the solar panel line is connected reversely, the output voltage of the solar panel is lower than the battery voltage, and the output voltage of the solar panel is greater than the maximum PV input voltage.
(DCheck if the polarity from the PV terminal to the controller is correct.Check the output voltage of the solar panel. If the output voltage of the solar panel is lower than the battery voltage, you need to connect the solar panels in series to increase the voltage; if the output voltage of the solar panel is higher than 150V, you need to reduce the output of the solar panel.
Why does the controller show that the output current is very low?
CDT output current may be low due to weak light or shadows of solar panels.
The battery may enter the float charge stage and therefore the current drops. You can use a multimeter to check the battery voltage to determine whether the battery enters the float charge stage.
What matters should be paid attention to in the daily use of the controller?
CD Ensure that the system voltage and battery type of the controller are set correctly. @The controller should be installed as close to the battery as possible to avoid the voltage drop caused by too long wires, which will affect the normal voltage judgment.
The controller should be installed in a well-ventilated, non-humid environment.
What should I pay attention to when connecting to APP?
CDBluetooth function is available and turning on in your mobile phone. CPS function is available and turning on in your mobile phone. Android firmware version 5.0 or above, or 105 firmware version 9.0 or above.
