Check the listing for details. 1400W Off Grid Solar Wind Turbines MPPT Charge Controller 12V Boost Regulator. Color: Black, Condition: New. Listed at 79.99 USD. 1400W Off Grid Solar Wind Turbines MPPT Charge Controller 12V Boost Regulator Features: Super intelligent (economical) solar&wind hybrid controller is a high cost-effective simplified version of super-intelligent (advanced) controller. It remains most of the practical functions, such as speed control, over-current, over-voltage Limit protection, etc., compression of the scalability, so there is a high cost. Suitable for high-volume low-cost use. Performance features 1.Waterproof. Waterproof, anti-corrosion, insulated protections are specially designed for circuit board. The housing is also waterproof. 3.No damage would happen when solar power input is reverse-connected sustainedly. Controller will go on working after correcting the reversed connection. 4.Boost MPPT input technology.The controller provides automatic wind turbine MPPT(input maximum power tracking) mode, or 5-segment matching curve input configuration mode (RPM vs input current curve, or input voltage vs input current curve), which could maximize the power generation sufficiency under low wind speed. For 12V battery, start charging voltage 6V; For 24V battery, start charging voltage 12V. 5.multiple output modes. The controller provides a variety of output modes(light control, time control, morning light) feasible for various applications. 6.The controller could calculate cumulative power generated, remaining power, RPM, current, temperature and other data. The controller displays not only conventional data such as output current/voltage/power of wind turbine/solar panel/battery, but also the cumulative power generated by wind/solar, remained battery power and RPM. Wind: input voltage/current/power/cumulative power/RPM/unloading current Solar: input voltage/current/power/cumulative power Battery:Voltage/charging current/power/cumulative power 7.Protections: Wind: Over speed protection,over current protection, induced lightning strike protection Solar: Reverse connection protection Battery: Reverse polarity protection(fuse burn-out）, over voltage protection, low voltage protection(for street lights) Insulation Grade: IP41 Specification: Condition: 100% Brand New Material: Alloy Rated Voltage: 12V/24V automatic recognition。 48V Photovoltaic Power: 400W Wind Dynamo Power: 1000W Ambient Temperature: -25℃- +55℃ Suitable Altitude: ≤5500M Protection Type: Lightning Protection,Solar Reverse Charge Protection,Battery Open-circuit Protection,Battery Reverse Protection, Over Wind Speed and Over-voltage Soft Automatic Brake Protection, Overload Protection Size: 16*15*6cm/ Weight: approx.874g Package List: 1 * Wind Solar Hybird Controller 1 * Instruction Note: 1.
