Ensure no short circuits occur in the battery pack. We recommend installing appropriate slow-blow fuses in the circuit to ensure the safe utilization of rated current. 2.Battery packs emit flammable gases. Place battery packs in well-ventilated areas, away from open flames. Prevent wire and terminal short circuits, as some terminals or wires might generate voltages and currents twice the rated voltage and current of the battery pack. Always use insulated tools during operations. 3.Keep children away from battery packs and controllers to ensure their safety. 4.Follow the safety recommendations of the battery pack manufacturer to ensure correct product usage. 5.When installing this controller, avoid directly mounting it on metal supports to minimize potential electromagnetic interference. Scope of Application: This controller is suitable for solar panel inputs ranging from 12V to 50V and can boost output voltage from 24V to 88V for battery packs. The battery packs can be open or sealed lead-acid battery packs, and it also supports lithium iron phosphate and lithium batteries. System Operation: Upon proper connection, the system starts automatically in sunlight. LED digital display lights up, signifying system initiation. Post initiation, the LED digital display shows photovoltaic panel current, power, and battery voltage. When the charging current reads 0.0A, the battery pack is fully charged, and charging stops. Setting Battery Pack Charging Voltage: Connect the photovoltaic panel and simultaneously hold the plus and minus buttons. The LED digital display will blink. Use the plus and minus buttons to set the charging voltage, and release the buttons to complete the setting. Usage Usage Suggestions: Avoid overloading the controller. For an 18V system, the maximum power is 300W. If using two 18V solar panels, connect them in series or parallel. For a 36V system, the maximum power is 450W. If using more than two panels, connect them in parallel. As the controller generates heat during operation, ensure installation in well-ventilated environments. We recommend installing a switch between the battery pack and controller to ensure safety during wiring. Regularly fully charge the battery pack. Charging at least once a month is essential to prevent battery damage. Important Notes-Please carefully read and adhere to the following safety instructions: Strictly prohibit exceeding rated voltage and power ranges. Overvoltage and overpowering may lead to equipment damage or danger. Correct voltage setting: Before installing the controller, ensure the selected voltage setting matches the battery voltage. Charging a low-voltage battery with a high-voltage setting can lead to improper charging and battery damage. Installation steps: When installing the controller, follow these steps: a. Firstly, correctly connect the solar panel to the controller's input terminal.        b. Next, connect the battery to the controller's output terminal. Ensure the red wire of the input and output lines is connected to the positive terminal, and the black wire is connected to the negative terminal. Wire length: To minimize energy loss, keep the wire length connecting to the controller as short as possible. Solar panel placement: When using solar panels, place them in an area with ample sunlight and no obstructions. Obstructions can impact panel efficiency, leading to decreased system performance. Ventilation and cooling: The controller generates heat during operation. To ensure long-term stable operation, install the controller in a well-ventilated environment to prevent overheating. Fuse replacement: Strictly avoid replacing fuses with those of higher ratings or using substitutes like copper wire. The controller's fuse is rated at 15A. Proper fuse usage effectively protects the circuit and ensures device safety. Adhering to the above instructions will enable you to use our MPPT solar boost controller correctly and safely.
