HEMK Gen3 Power Module
Freesun HEMK Utility Scale Solar Inverter
The HEMK GEN3 is our third generation 1500V inverter, based on the more than proven HEMK GEN2 and HEC V1500 products. This modular solar inverter offers the advantages of both central and string inverters. Achieving a very high-power density, and a maximum output power of 4.39MW, it is available in 6 different AC voltages, providing the flexibility to choose the best solution for each PV plant.
The power stage architecture, composed of four field replaceable units (FRU), is designed to provide the highest availability and optimize yield production.
The innovative cooling system allows the HEMK GEN3 to be installed in the harshest environments. This advanced air-cooling system, reduces the OPEX cost compared to other cooling solutions, that need the use of complex liquid-cooling systems.
EASY MAINTENANCE
The advantages of a central inverter with the modularity of the string inverters.
BUS PLUS
The Bus Plus feature allows the connection of up to four Freemaq DC/DC converters. It is the most cost-competitive solution for solar-plus-storage retrofits.
ACTIVE HEATING
When the unit is not actively exporting power, the inverter can import a small amount of power to keep the inverter internal ambient temperature above -20°C, without using external resistors.
ADVANCED GRID
Capable of operating on any power system. Offering advanced grid support functionalities like fast frequency response and synthetic inertia among others
THREE-LEVEL TOPOLOGY
The 3 level IGBT topology reduces stage losses, increases inverter efficiency, and minimizes total harmonic distortion. High efficiency to deliver the lowest cost of energy (LCOE).
