Specifications Item Type: Wind Solar Hybrid Charge Controller Host Size: Approx. 174 x 145.5 x 70 mm / 6.9 x 5.7 x 2.8 in Shell Color: Green Material: ABS System Rated Voltage: 12/24V automatic identification Model GPI-4030 GPI-6060 GPI-1010K Battery Voltage 12V 24V 12V 24V 12V 24V Wind Turbines Rated Power 200 400 300 600 500 1000 PV Module Rated Power 150 300 300 600 500 1000 Maximum Input Voltage: Wind turbines <80V, solar panel <95V (12V/24V controller) No Load Current (DC): ≤0.05A The Controller Takes Power: Battery or photovoltaic panel to take power Control Method: Fan MPPT boost charging function, PWM unloading function, PWM overcurrent limiting function Load: A variety of working modes are available: pure light control mode, normally open mode, light control + time control mode (four periods + morning light) Display Mode: LCD, Chinese display, clear and intuitive Display Parameters: Voltage, battery power, current, power, load mode, temperature, etc. Protection Type: Solar battery anti reverse charging protection, battery open circuit protection, battery reverse connection protection, overcurrent and overvoltage soft automatic braking protection, overload protection, etc. Heat Dissipation Method: Aluminum heat dissipation and self cooling Operating Temperature And Humidity Range: -20~+55℃/35~85%RH (but no condensation) Weight: Approx. 2289g / 80.7oz Applicable Battery: General acid lithium battery Application: Wind solar hybrid energy storage power station, wind solar hybrid monitoring system, wind solar hybrid lighting system Failure Analysis: When the fan is connected to the controller, the speed of the fan becomes very slow immediately? 1. The battery voltage arrive the floating charging point 2. The rated output voltage of the fan is much higher than the rated voltage of the battery, because the fan speed is proportional to the output voltage, and the fan voltage is dragged by the battery and will not be very high, so the speed will be very low 3. The unloading tube was burnt out in the wrong operation Why does the controller unload when the LCD displays a small current value? The controller controls the unloading by detecting parameters such as battery voltage, charging current and temperature. When the floating charging voltage point is arrived, or when high temperature protection is arrived, no matter how large the charging current is, the fan will unload. LCD does not display? 1. The battery is in poor contact, please check the battery connection cable. 2. The battery is damaged, please check and replace the battery. No charging current? If the charging voltage is not arrived, the input voltage of the solar panel must be higher than the battery voltage before it can be charged. The fan needs to arrive a certain wind speed in order to generate electricity normally. Package List 1 x Controller 1 x Resistance 2 x Cable 2 x Screw 2 x Nuts 1 x Manual
