Features 1LCD Display: With rich content for the LCD screen display and simple query setting the automatic wind solar charge controller can switch Chinese and English. Lithium battery is equipped with dedicated activation and stable charging function. 2Convenient: The acid batteries ternary lithium batteries lithium iron phosphate batteries and user defined batteries can all be used which is convenient for users to choose. 3Heat Dissipation: Equipped with aluminum shell whose plate can self cooling and dissipate heat. The load output can be adjusted in various working modes. The internal circuit board of the controller is sprayed with three proof paint to prevent dust moisture and static electricity. 4USB Charging: Adopted MPPT control algorithm design the 48V LCD wind solar controller can be charged more efficiently including USB charging function can be used in mobile phone charging also can exert the maximum power of the battery board provide a larger charging current. It can generally improve the energy utilization rate by 15 percent to 20 percent than the PWM controller. 5Dual Channel Power: Adopted high accuracy sampling chip control which can maximum rational use of battery energy with dual channel power supply function of the wind solar controller battery and solar energy.

Before installation and maintenance ensure that the controller is in a safe and de energized state.2. Please install the controller in a dust?free dry and ventilated place and avoid rainwater infiltration and direct sunlight.3. When installing in the cabinet there should be enough space around the controller or reliable heat dissipation through the box.4. Keep away from corrosive gas and strong electromagnetic interference.5. The installation site should be convenient for personnel to carry out installation electrical connection and later maintenance.6. Virtually connected connection points and corroded wires may cause great heat to melt the wire insulation burn the surrounding materials and even cause a fire so make sure that the connectors are tightened and the wires are best fixed with cable ties to avoid Wires shake when moving causing loose connectors.7. When connecting the system the voltage of the output terminal of the component may exceed the safety voltage of the human body. When it is necessary to operate pay attention to the use of insulating tools and ensure that your hands are dry.8. The battery terminals on the controller can be connected to either the same battery or the same group of batteries. The subsequent instructions in the manual are for the use of a single battery but are also applicable to a system of a group of batteries.9. Follow the battery manufacturer's safety recommendations.10. The system connection line should be selected according to the current density not greater than 5A/mm.
