3300 kVA - 3630 kVA
500 kW - 3000 kW (DC/DC)
The HEM HYBRID inverter is designed for utility scale solar-plus-storage applications, which require the advantages of a central inverter solution but also the modularity of a string architecture. It can include up to six DC/DC converters of 500 kW each one, fully compatible with different battery technologies and manufacturers. It also has the added advantage of having an integrated medium voltage transformer and switchgear.
FIELD REPLACEABLE UNITS
All in one
The Freesun HEM HYBRID inverter is the only solar inverter on the market to integrate up to six DC/DC converters of 500 kW each one, and the transformer and medium-voltage cells into the same set of equipment. Its use in utility-scale plants delivers considerable savings in terms of CAPEX, while greatly simplifying design and installation.
The Freesun HEM HYBRID device integrates the DC/DC converters, as well as the MV transformer and switchgear, reduccing the needs of additional connections.
The HEM HYBRID gets the maximum revenues from the PV generator by charging the battery storage system when the PV inverter is clipping the output power, due to the high DC/AC power ratios. This stored energy can be exported to the utility grid when the price per KWh is high.
Field Replaceable Units
The Freesun HEM HYBRID device consists of six FRUs (Field Replaceable Units) for DC/AC conversion and up to six FRUs for DC/DC conversion, designed, as the name implies, for easy replacement in situ.
iCOOL 3 is a ventilation system designed to supply a constant flow of clean air to the inside of the equipment without any need for dust filters or liquid cooling systems.
This innovative control mode allows you to reduce medium-voltage transformer loss by up to 25%, and also to cut the plant’s power consumption.
Multilevel topology is the most efficient way of addressing the management of high DC voltages. This three-level configuration reduces losses at the power stage, increases efficiency and minimizes overall harmonic distortion.
The Freesun HEM HYBRID unit comes with a high level of protection against external agents such as rain, snow and ice. It is fitted with insulating panels designed to shield it from solar radiation and a casing that provides C4 corrosion protection by default.
During the night, when the inverter does not actively export power, it can import a small amount of energy to prevent internal condensation – without any use of heating elements.
The Freesun HEM HYBRID is fitted with all the medium-voltage elements. This compact solution simplifies the task of designing the installation, while also reducing connection costs and therefore minimizing the LCOE. Its front access also makes it easier to maintain.
Freesun HEM HYBRID inverter modules offer a useful service life of more than 30 years’ operation in aggressive environments and under extreme weather conditions. They are tested and configured to withstand anything from the sub-zero temperatures of the Siberian tundra to the searing heat of California’s Death Valley.
Power Electronics opens its first delegation in Southeast Asia with the aim of positioning itself in a region with very good growth prospects in the use of renewable energy. By 2040, photovoltaic solar energy will have surpassed coal as the largest source of energy and will provide 49% of the region's electricity needs. Renewable energies are expected to provide 84% of total energy generation by 2050.
Power Electronics has launched the HEM HYBRID, the latest solution for utility-scale PV plants, a solar inverter unique in the market that allows interconnection with battery-based storage systems, through the DC / DC integrated in the same enclosure. The new solar-plus-storage inverter has been presented at the North America Smart Energy Week held at the Salt Lake City International Solar Power International.
Power Electronics will be attending Solar Power International (SPI), Energy Storage International, and North America Smart Energy Week at the Salt Palace Convention Center in Salt Lake City, Utah, from 23 to 26 of September. This is the largest gathering of industry experts, leaders, and professionals from the solar, energy storage, smart energy, microgrid solutions, and EV infrastructure industry in North America.
