General Safety Information

1. Read all of the instructions and cautions in the manual before installation.
2. There are no repairable parts for this controller, do not disassemble or attempt to repair the controller.
3. Keep the controller from the water.
4. Make sure all connections with controller are tight.

Charge Controller Safety

1. NEVER connect the solar panel array to the controller without a battery. The battery must be connected first.
2. Ensure input voltage does not exceed 150 VDC to pre­vent permanent damage.
3. Ensure that the output current of the solar panel does not exceed the rated charging current of the controller.

Battery Safety

1. Do NOT let the positive(+) and negative(-) terminals of the battery touch each other.
2. Explosive battery gases may be present while charging. Be certain there is enough ventilation to release the gases.
3. Be careful when working with large lead-acid batteries. Wear goggles and have fresh water available in case there is contact with the battery acid.
4. Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them. Too high of an equalizing charge or too long of one may cause damage. Please carefully review the specific requirements of the battery used in the system.

Features

1. Aluminum shell and tempered glass cover, the controller has good heat dissipation effect.
2. Built-in BT communication module mobile phone APP operation {Android and 105).
3. Filled with silicon/polyurethane inside for better cooling and waterproofing.
4. Compatible with lead-acid batteries and lithium batteries, support 12V/ 24V battery system, and can automatically identify the voltage of lead-acid batteries.
5. Backlit display on the screen, touch button operation.
6. Built-in reverse connection protection, open circuit protection, high temperature protection, over current/short circuit protection, all of which are self-healing, no damage to the controller.

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 (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 lSOV.
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.

Wiring Instructions

1. Remove the magnetic cover. (Pick up)
2. Put the magnetic cover aside.
3. Unscrew the screws. (Counterclockwise)

4. Plug the cable into the correct port.
5. Tighten the screws. (Clockwise)
6. Check the wiring condition and put the magnetic cover back.

APP operation

1. Click the “BT icon” in the upper right corner to search for the BT device “PVChargePro”.
2. Click the “menu” in the upper left corner to check whether BT is connected.
3. Click “Parameter Setting”  in the bottom right Paramater ettmgs corner to set the parameters.
4. Click the “unlocked” Locked I lock shape icon to confirm the unlocking for parameter setting.
5. Select the battery type, {FLD, SEL, GEL) battery do not need to set other parameters because the voltage is automatically identified by default, and other parameters are in accordance with the default values.
6. Select LI, you need to manually click the system voltage to set the voltage, other parameters are recommended to follow the default value {the boost charge voltage is allowed to set}.
7. Select USE, you can set all parameters.
8. Click to confirm after setting the above parameters.
9. The “Real-Time Monitoring” can check the real-time working status of the solar system, and the “Historical Data” can check the historical working status of the solar system.

APP MAIN INTERFACE

Lead-acid Battery Working Stage

1. Lead-acid Battery Working Stage
2. Bulk 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.

3.  **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.
4.  **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 AGM 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. Bulk 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.
