Solar Charge Controller BSC8048 Series Specification:

System Connection:

Order of Connection:

① Connected with Battery first; ② Connected with Load; ③ Connected with Solar Panel.

Note:

① This series is a positive ground controller. Any positive connection of Solar Panel, Load or Battery can be earth grounded;
② The fuse should be installed as close to battery as possible, the suggested distance is about 150mm;
③ If inverter or other load with big start current is necessary in system, please connect it with Battery, not solar controller;
④ When disconnecting the system, the order will be reversed.

Operation:

LCD Symbol:

Button Function:

Browse Interface:

NOTE:

① After connected with Battery, LCD will go into an interface that automatically recognizes the battery voltage level, 3 seconds later, it will enter to the main interface of LCD;
② Equalizing charge will be after every 90 times Floating charge, or one charge in three months;
③ Default maximum charging current of Lithium battery is 5A, but it can be adjusted by users within the rated current range.
④ Under the interface of Accumulated KWH, long press button “＋” to clear the value; ⑤When no operation 30s, the interface will be back to main interface, and back-light will be turned off.

Battery Types：

Under the interface of battery types, long press button “＋” into the type setting, then short press button “＋” or “－” to choose battery type, and then long press “＋” again to save and exit.

Battery voltage automatic identification range:

Control Parameters Of Lead-acid Battery:

Control parameters of Lithium battery:

 Load Working Modes：

Under the load mode setting interface, long press button “＋”, when Timer 1 or Timer 2 begin flashing, short press button “＋” or “－” to set parameter, then long press button “＋” to save and exit.

Protections:

• Solar Panel Reverse-Polarity: If the solar panel is connected with controller in reversed polarity, controller will not be damaged and will work as normal when correctly connected.
• Battery Reverse-Polarity: If the battery is connected with controller in reversed polarity (solar controller is not connected with solar panel), controller will not be damaged and will work as normal when correctly connected.
• Battery Reverse-Discharge: Controller is able to protect battery from reversed discharging to solar panel at night.
• Over-Heating Protection: Once the internal temperature is detected to be higher than a certain value by the controller, it will stop charging the battery and then recharging the battery automatically after the temperature drop to a certain value.
• Battery Over-Current: Controller will stop charging when excess current is detected from the solar panel, and recharging automatically after 2 min.
• Load Over-Load: The load will be turned off when the output current of load exceeds its rated current for a while, and turned on automatically after 2 min.
• Load Short-Circuit: Controller will be in protection state when the load is short circuit, and recharging automatically after 2 min.
• Battery Low-Voltage: Controller will turn off the load when the battery voltage is lower than the value preset for low-voltage disconnection, and turn on the load when the battery voltage reaches the value preset for low-voltage re-connection. The value for low-voltage disconnection and low-voltage re-connection can be set by users in a certain range.
• Battery Over-Voltage: Controller will turn off the load when the battery voltage is higher than the value preset for over-voltage protection, and turn on the load when the battery voltage is 1V lower than the value preset for over-voltage protection.
• Lightning Protection: The lightning protection function of controller is limited and it is recommended to install devices for lightning protection on the input side to increase system reliability.
