Lindsay Gorrill is CEO of KORE Power, a North American company that produces and installs high density, high voltage battery energy storage systems. KORE Power /// korepower.com 1 https://www.strategen.com/ reports-1/09-20-2017/new-york-best Inverter for solar and energy storage plants Power Electronics has presented the HEM HYBRID, its latest solution for largescale photovoltaic plants, a solar inverter that allows interconnection with battery-based storage systems through the DC / DC integrated in the same enclosure. The HEM HYBRID integrates up to six DC / DC converters of 500kW each, without the need for additional connections. In addition, its structure incorporates medium voltage equipment, transformer, and protection cell, as well as offering the advantages of a central inverter and the modularity of a string architecture. The HEM HYBRID obtains the maximum benefit of photovoltaic generation by charging the battery system when the solar inverter is limiting the output power due to a high DC / AC ratio. This energy is stored and can be exported to the electricity grid when the price per KWh is higher. Its modular structure, based on easily replaceable power stages, (Field Replaceable Units) allows users to maximize its availability and performance. On the other hand, the use of this inverter in solar plants represents a considerable saving in CapEx and simplifies the design of the installation, achieving a low LCOE. Maintenance is also easy thanks to the front access that allows the modules to be replaced in the field, reducing the MTTR and obtaining a low OpEx.
