To improve the access capability of the FusionSolar Smart PV Management System, the system needs to be
            expanded and
            upgraded, which is expected to be implemented on December 25, 2021. To ensure that services are not
            affected, you
            need to upgrade the FusionSolar app to 5.7.059 or later in advance to adapt to the system after capacity
            expansion.
        
        
            The new app can generate the remote physical layout diagram of the optimizer and optimize the display of the
            optimizer and the energy management curve, greatly improving the overall user experience.
        
        
            FusionSolar 5.7.059 has been released on Huawei AppGallery and App Store on November 10, 2021.
