    The new downvoltage mppt photovoltaic controller is a kind of solar power generation equipment. Mppt (maximum Power Point tracking) algorithm is used to make full use of solar photovoltaic energy. PV wide voltage range input, can charge a variety of batteries. And three-stage charging effectively improves the life of the battery. Modular design of the controller, can be used in parallel, so that the customer configuration is free and flexible.

    1. 1.Industrial grade materials are used to ensure the stable and reliable;
    2. 2.Memory function of the equipment, storage settings, date and time power generation and other functions.
    3. 3.Charging methods: three-stage charging (constant current, constant voltage, floating charging), Effective prolongation of battery life
    4. 4.LED and LCD display a variety of parameters, such as model, PV input voltage, battery type, charging voltage, charging current, charging power, working status and other photovoltaic input using mppt tracking technology;
    5. 5.Automatically let the photovoltaic module work at the best power point, multiple devices can run in parallel, expand the scope of application, and meet the charging requirements under high power.
