Currently, the team manages nearly 200 photovoltaic sites distributed across Taiwan, and each site is very important to the boss and investors. During the limited sunlight hours, timely inspection and identification of abnormal sites, obtaining abnormal information, and quickly resolving issues are crucial tasks that impact revenue. Every day when Yi-Lang arrives at the office, the first thing he does is open the PHOTON system's maintenance overview page. By using the color-coded icons of the devices, he can easily tell the operating status of inverters at each site. By clicking on abnormal equipment, he can view event information directly. If there are any issues, he can immediately assign work through the system. Maintenance personnel can also check the abnormal locations via their mobile phones when they arrive on site for quick repairs.
