1. Product Introduction   MPPT30 controller is a kind of intelligent, multi-purpose solar charge controller. It uses the fixed LCD display, with a very friendly interface; various control parameters can be flexibly set, fully meet your various application requirements. MPPT30 controller has following features: ①    MPPT function: The most important feature of this controller is intelligently tracking input voltage from solar panels, and this can let solar panels always work at Maximum Power Point of V-A curve. Compared with normal solar charge controller, this MPPT controller can increase the generating efficiency of solar panels by 10% to 50%. ②    Vivid LCD screen signal and precise operation ③    Intelligent PWM charging mode with auto temperature compensation ④    Adjustable charging and discharging parameters, and settable load working state ⑤    Different protection function for battery, including protection against reverse charging for battery, battery low voltage protection and protection against battery reverse connection
