Charge Controller Safety

Charge Controller Safety

1. NEVER connect the solar panel array to the controller without a battery. The battery must be connected first. This may cause a dangerous occurrence where the controller would experience a high open-circuit voltage at the terminals.Ensure input voltage does not exceed 50 VDC to prevent permanent damage.
2. Use the Open Circuit (Voc) to make sure the voltage does not exceed this value when connecting panels together in series.
3. The charge controller should be installed indoors in a well-ventilated, cool, and dry environment.
4. Do NOT allow water to enter 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 eye protection 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.

System Wiring

1. Connect the battery to the solar charge controller FIRST, ensuring polarity correct.
2. Then connect the positive and negative poles of the load to the load terminals of the controller.
3. Finally, connect the positive and negative poles of the solar panel to the PV terminals of the controller.

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

Caution

1. First, make sure your battery system is 12V or 24V. Ensure that the maximum open-circuit voltage of the solar system does not exceed 50V.
2. Ensure that the maximum output current of the solar panel does not exceed 30A.
3. Ensure that the voltage of the solar panel is higher than the battery voltage.

Some inductive or capacitive loads will have a large current at the moment of starting, which may trigger the short-circuit protection of the controller and cause the output to shut down. At this time, the user can turn off the short- circuit protection function.

Setting method: Same as above.

Working Stage

Lead-acid Battery Working Stage

1. 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 equalizing charging voltage).
2. 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 is 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 b01, b02, b04 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. Boost Charge Stage: constant current charging, providing the maximum current to the battery until the battery reaches the boost charge voltage. Ternary lithium battery, LiFePO4, LTO can be adjusted the boost charge voltage.
2. Disconnect Charge stage: when the battery reaches the boost charge voltage, the charging will be disconnected. When the battery voltage reaches the boost charge return voltage, the battery enters the boost charge stage again.The boost charge return voltage, reduce 0.5V (U12V system) / 1.0V (U24V system) on the basis of the boost charge voltage.

Frequently Asked Questions

A1

| Send the following information to the email:

service@bougerv.com ,

1        The connection method of the solar panels (series/ parallel, quantity, voltage, power).

2         The voltage and battery type of the battery.

3         The display data of the controller: battery voltage, battery charging current, the output voltage of the solar panel.

Please provide these above information with picures

and video, BougeRV will provide you with technical support faster.

 |
Q2| Why does the controller show that the output current is very low?

A2

| 1        The output current may be low due to weak light or shadows of solar panels.

2         The battery may enter the float charge stage and therefore the current drops. You can use a multime- ter to check the battery voltage to determine whether the battery enters the float charge stage.

A3

| 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 higher than the maximum PV input voltage.

1        Check whether the line from the PV terminal to the controller is correct or not.

2         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 50V, you need to reduce the output of the solar panel.

 |
Q4| How to maintain the controller in the daily use of the controller?

A4

| 1        Ensure that the system voltage and battery type of the controller are set correctly.

2         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.

3         The controller should be installed in a well-ventilated, non-humid environment.
