Sungrow is the world’s most bankable inverter brand with over 224 GW installed worldwide as of December 2021. Founded in 1997 by University Professor Cao Renxian, Sungrow is a leader in the research and development of solar inverters, with the largest dedicated R&D team in the industry and a broad product portfolio offering PV inverter solutions and energy storage systems for utility-scale, commercial, and residential applications, as well as internationally recognized floating PV plant solutions.
Sungrow releases its brand new “1+X” modular Inverter here in India. The brand-new central inverter “1+X” Modular Inverter is the most innovative central inverter solution which Sungrow is promoting worldwide, and it is expected to lead the next generation central inverter designation for large-scale utility solar plants. The cutting-edge technologies of this product center one keyword— “Modularization”. “1+X” inverter solution boasts modularization at the inverter level, the system level and the component level. Three-level modularization makes power plant design more flexible and post O&M more convenient in the future. Firstly, “1+X” modular inverter features 1.1MW single unit as the minimum, but the block capacity can be expanded to the max. 8.8 MW by combining 8 units just like building blocks. Customers can choose from 1.1MW to 8.8 MW to meet their best demands. Secondly, the system modularization makes PV module configuration more flexible to extend. The inverter supports maximum 2 times DC/AC ratio. 1+X modular inverter has 42% more MPPT than the traditional central inverters, and it realizes the string-level management by new wireless DC combiner. Increased MPPT and more refined management lead to higher electricity generation. The DC/ESS interface built in this solution also supports connecting to energy storage system, enabling customers to enjoy the storage function for future energy usage. Thirdly, the component modularization realizes the plug and play function, reducing the maintenance from 6h to 2h. Moreover, since each inverter also works in individual unit, it can be directly replaced by onsite backup inverter if failure occurred. Hence, the three-level modularization, once again, sets this gigantic product apart from others.
