Description of the object Condition: 100% New Manufacturing: China, Chinese products of local factory for sale This controller can be used to charge lithium, lithium iron phosphate or lead acid batteries. The wind charging circuit of this controller features advanced MPPT boost charging technology to extract the maximum possible power from the wind turbine in low wind speeds. The solar charging circuit of this controller uses MOS tube PWM technology, which minimizes the power consumption of the controller and makes the system more stable. Dual power supply function - controller can be powered with battery / solar power supply. Large LCD display dynamically displays all the operating data and working condition, working modes and parameter configuration can be conveniently switched. DC output with 3 output modes. The inner circuit board is sprayed with conformal coating to prevent dust, moisture and static electricity. Wind generator MPPT boost charging function. PWM dump load of wind, external dump-load resistance, intelligent disconnection of Solar charging. Dual power supply function: Battery + solar power supply. LCD displays parameters such as voltage and current of wind, solar and load .Some parameters can be set by users. DC output with 3 output modes. The inner circuit board of the controller is sprayed with conformal coating to prevent dust, moisture and static electricity. About LCD screen Showing: English showing Battery voltage and power Photovoltaic voltage, current and power display Wind turbine voltage, current and power display Cumulative power generation display Charge and discharge data can be set freely Protection Explanation Reversed charging Protection of solar Such as at night, the voltage of the battery may be higher than solar panel. The controller protect the battery from charging the solar panel. Reverse polarity Protection of battery When the battery polarity is reversed, the controller does not work and there is no display. The fuse protects the internal circuit. If the battery does not work properly after it is connected correctly, just need to replace the fuse . Battery open circuit Protection After long-term use, the battery may be Open-Circuit or poor connect. The controller can protect itself from damage .Check the connection regularly Over voltage Over current Over load voltage Protection When its strong wind or over voltage, the controller will automatically start braking function to protect the wind generator and battery. The controller will automatically cuts off the circuit when the output is over voltage. Lightning Protection Lightning protection refers to the last level of protection necessary for equipment. For lightning-prone areas, special lightning protection devices and other components of the multilevel lightning protection system are needed. It need additional payment If the user need this function. Product includes 1 x Solar Charge Discharge Booster Controller Friendly Tips Photo color might be a little different from the actual product due to color display of different monitors. The size is measured by hands, please allow minor error of measurement. Please do not hesitate to contact us if you have any other questions or require additional information.
