Photon grade are A+ in both high irradiation and medium irradiation. It got BDEW, GOLD SUN certifications and total 22 standards (13 states), etc. It is capable for ±0.8 PF adjustable, GFDI, LVRT, and multi MPPT. Zero delay of schedule. Sun600 designed a new patent-topology with TCM work mode, max efficiency is 97.9%.These are in mass production in 4 factories both China and Brazil.Project2: Firmware architecture for digital loop controller Achievements: As a member of firmware structure team, discuss the common issues of UPS, solar inverter, converter. As the owner of solar inverter, I developed the solar inverter’s firmware platform. It summarized the key components and setup a firmware construction. Based on this, a new digit controller firmware is easy to build even by a junior engineer. They are just to put some tasks to certain functions. It is also easy to test and very helpful for the schedule.
