Specification:Item Type: Wind Solar ControllerMaterial: Aluminium AlloyWeight: Approx. 2006g / 70.8ozShell Color: BlueSize: Approx. 148 x 162 x 85mm / 5.8 x 6.4 x 3.3inProduct Introduction: This wind solar controller is specially designed for small off grid wind solar power generation systems. It is easy to operate, and can safely and efficiently control wind turbines and photovoltaic modules to charge batteries.Function: 1. Fan overcurrent limitThis product provides the fan overcurrent limit. Once the fan exceeds the set upper limit current, the controller automatically starts PWM intelligent unloading to the fan.2. Intelligent current limit of battery maximum currentYou can manually set the upper limit of the battery capacity on the controller based on the actual system conditions. The controller calculates the upper limit of the charging current (that is, 0.3 times the battery capacity) based on the upper limit of the battery capacity to the battery.3. Manual brake function4. Fan and photovoltaic charging switch functionOn the controller, you can manually set the fan and photovoltaic charging on or off.5. Load output switch functionOn the controller, the user can manually set the load side on or off.6. The load output has 4 kinds of diversified working modes.7. The load output has the functions of boost constant current source and constant current source for users to choose.Electrical Parameters:Fan Rated Power: 100W-1000WPhotovoltaic Rated Power: 100W-1000WRated System Voltage: 12V-24V automatic identificationNote: The above three parameters must meet the conditions: (rated power of fan and rated power of photovoltaic) / rated current of system ≤ 50AFan Maximum Access Voltage: 80VPV Maximum Access Voltage: 80VFan Unloading Method: Built in electronic unloadingFan Protection: Overcurrent protection unloading, manual brake unloadingLoad
