    Higher Yields, Never Stop

    High Reliability

    With 20 years technology accumulation in telecom power, Huawei builds

    inverter product on the same platform. Huawei inverters have passed the

    strictest testing above industry level, and approved by the global certification

    authorities including TUV.

    With Smart Logger and iManager NetEco 1000S, Huawei inverters realize

    remote management and grid management.

    Higher YieldsHigher yields is the constant pursuit of Huawei Solar Inverter.

    With leading topology and control algorithm technology, Huawei inverters have

    achieved industry-leading efficiency, and SUN2000-20KTL Photon test result is

    A+/A+ at medium and high irradiation with normal silicon devices.

    Depend on overload capacity and good performance at low irradiation, as well

    as more flexible MPPT, Huawei inverters maximize the power yields.
