    WS-MPPT60 SOLAR CONTROLLER

    DC to AC controller

    This WS-MPPT solar controller (also known as WELLSEE intelligent solar charge controller, solar charge

    controller, PV controller) can intelligently regulate the working voltage of solar panels, letting the solar

    panels always work at Maximum Power Point of V-A curve.

    Compared with standard solar controller, this

    MPPT controller can increase the efficiency of PV modules by 10%-30%.

    WELLSEE WS-MPPT solar

    controllers 10A-60A include 12V series, 24V series and 48V series.

    MPPT advantage:

    Maximum Power Point Tracking (MPPT in short) system allows PV panels to output more Power by

    adjusting working condition of the electrical module.

    In Figure1 A indicates that the working state of

    ordinary controller, that is PV battery working on 12V , only outputting a power point of 53W (the general

    power point), B indicates that MPPT controller makes PV battery always work at the maximum power

    point, thus outputting the power point of 75W (the maximum power point).

    Product features:

    Applicable to various types of batteries,

    MPPT function

    Microprocessor controller pulse width modulation (PWM) charging

    Temperature sensor battery charging compensation

    Overload protection (automatic restoration)

    Overcharge protection

    Short circuit protection (automatic restoration) ,

    Lightning protection

    Reverse discharge protection

    Reverse polarity connection protection (automatic restoration)

    Under voltage protection

    MPPT principle:

    The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine.

    With the intensity of sunshine being constant, the maximum output power decreases with the rise of the

    temperature.

    The temperature being constant, when the sunshine intensifies, the open circuit voltage of

    PV battery basically keeps unchanged.

    But the short circuit current increases substantially, thus the

    maximum output power increases substantially.

    This WS-MPPT solar controller can intelligently regulate the working voltage of solar panels, letting the

    solar panels always work at Maximum Power Point of V-A curve.

    Compared with ordinary solar controller,

    this MPPT controller can increase the efficiency of PV modules by about 30%.

    However, due to many different factors, such as the difference in solar panel making, the change of the

    sun illuminance, change of temperature, the efficiency of the controller etc., the actually available

    increased rate is 10%-30%.

    Safe Trade Tips

    • Ask for business references and check them
    • Use a payment method that offers better protection for all such as Letters of credit and verified professional escrow services. Avoid payments in advance such as money transfers
    • Verify their business via their local Chamber of Commerce
    • Search the internet using their website address, their business name, their phone and fax numbers, and their email addresses to see if you can find any feedback about them.
    • Get to know more about scams and fraud to avoid: Internet Crime Complaint Center - Consumer Financial Protection Bureau
    • This site is never involved in any transaction, and does not handle payments, shipping, guarantee transactions, provide escrow services, or offer "buyer protection" or "seller certification"
