Sungrow’s “1+X” Modular Inverter Sungrow, the global leading inverter solution supplier for re- newables, officially launches the brand-new central inverter -- “1+X” Modular Inverter in a grand event hosted in Aerocity, New Delhi earlier this year. “1+X” Modular Inverter is the most innovative central inverter solution which Sungrow is promoting worldwide, and it is expected to lead the next gen - eration 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 conve - nient 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 flexi - ble 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-lev - el management by new wireless DC combiner. Increased MPPT and more refined management lead to higher electric - ity 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 us - age. 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. energetica INDIA- September_2022 80 PRODUCT FEATURE
