es 99%. It is designed with DC/AC ratio up to 1.8, enabling cost-saving on Balance of System (BoS) at large. The solution is compatible with the DC-coupling energy storage system, en- abling 60% of the rated power charge from the grid. The 1500V string inverter SG250HX, also applied to the utility-scale sector, and 3GW is expected to be deployed by the end of 2020. Targeting commercial and industrial rooftop installations, the cutting-edge portfolio ranging from 33kW to 110kW were on display. Sungrow is making remarkable inroads in the residen - tial segments including new three-phase hybrid inverter solu- tions, enabling a higher yield, more robust and safer perfor- mance with a user-friendly design. Kehua’s DC-DC bidirectional converter The function of the energy storage system is to store the photo- voltaic energy into the battery timely, and then input the electric energy into the power grid timely. Compared with AC-side en- ergy storage system, the DC-side energy storage system, for its higher efficiency, has more advantages in the application of photovoltaic power generation side. It is very important for DC- DC bidirectional converter, the most critical power conversion center for energy storage on DC-side, to adapt to the diversity of batteries and to own functional diversity. Based on a deep understanding of the development trend of energy storage, Kehua has developed the DC-DC bidirectional converter product that can meet the needs of multiple condi- tions, and has been applied in southern India for two years. After these two years of continuous verification and upgrad - ing, Kehua’s DC-DC bidirectional converter has been already equipped with various functions. Sofar Solar’s New Product Offerings for 2020 The new energy storage products Roadmap of Sofar Solar in 2020 includes high voltage and low voltage series batteries of 4-20kW three-phase energy storage inverter will be released in the near future. The new product is mainly oriented to the glob- al market. Both grid-connected and off-grid systems can be built into a multi complementary energy generation microgrid Solis’ 700W to 255kW Inverters for Residential, C&I, Utility Scale Ginlong Solis is one of the largest and most experienced string inverter manufacturing companies in the world. Solis inverters are recognized for their high quality, optimization for each local market and the profitability they offer to their clients. Due to the situation the world is going through and the impos- sibility for many people in the photovoltaic sector to attend the exhibition in Shanghai, Solis also organized its virtual version of Solis SNEC to receive its clients from all over the world virtually. Also, virtual visitors to Solis was able to learn about its broad product portfolio and its family of inverters with a range from 700W to 255kW, for residential, commercial industrial and utility applications.
