Power Electronics has presented the HEM HYBRID, its latest solution for large-scale photovoltaic plants, a solar inverter unique in the market that allows interconnection with storage systems using batteries up to 3,000 kW (DC / DC) of power. The new solar-plus-storage inverter has been presented at Solar Power International.
The HEM HYBRID is a solar inverter designed for large-scale photovoltaic plants that integrates up to six DC / DC converters of 500 kW each, without the need for additional connections. In addition, its structure, based on that of the successful HEM inverter, 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 contractors 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 considerably simplifies the design of the installation, achieving the lowest LCOE in the market. Maintenance is also easier thanks to the front access that allows the modules to be easily replaced in the field, reducing the MTTR and obtaining a lower OpEx.
