【Hybrid charge controller application range】: This hybrid charge controller fits all 12/24/48V batteries, including lithium battery. Fits max wind generator and max solar panels for wind solar complementary system for home, boat, street light. 【Operating System】: The wind turbine charging part has booster MPPT technology, which makes it charge continuously and efficiently even at low wind speeds. Stepless discharge function including external dump charging resistor solar panel charging uses PWM technology through MOS tube in series. 【Intelligent and Stable System】: The parameter is set perfectly after choosing the battery type. User can also customize according to their own needs. This system has been updated more intelligently to control the charging voltage with absolute stability. 【Display and DC charging mode】: larger LCD screen that is easy to browse and handle. Two DC load (output) with 4 output modes and each can be set different models. 【Protection Function】: reverse charging, sunlight protection, overcharge voltage/under voltage and overload protection, battery reverse and idle protection, protection, etc.
