HEC V1500

1050 kVA - 3500 kVA

565 Vac - 690 Vac

1500 Vdc

With more than 4 GW installed worldwide, the HEC V1500 has the best track record in terms of proven reliability and experience for utility-scale 1500 V solar inverters of the first generation. The HEC V1500 range includes a wide selection of models to choose from when deciding on the best solution for each project.






A wide range of power capacities.

Our HEC V1500 range of inverters includes 25 different models with power capacities ranging from 1 MW to 3.5 MW. It is available for both IEC and UL markets. The flexible modular design of Power Electronics offers smart solutions to meet the needs of any solar power project.


iCOOL V, an innovative and sophisticated ventilation system, allows the inverter to operate at its rated capacity at temperatures of up to 50ºC. It includes a smart system of variable-speed fans that allows you to reduce consumption at low power.

Multilevel Topology

Multilevel topology is the most efficient way of addressing the management of high bus voltages. This three-level configuration reduces losses at the power stage, increases efficiency and minimizes overall harmonic distortion.

Fail-Safe System

The topology of the HEC V1500 combines the respective advantages of a central and string inverter. If one module fails, its output power is distributed proportionally among the remaining active modules. The HEC V1500 is more efficient than a standard central inverter, as it only uses the power modules that are actually required when radiation levels are low.

Maximum Durability

The HEC V1500 unit comes with a high level of protection against external agents such as rain, snow and ice. It is also fitted with insulating panels to protect it from solar radiation.

Active Heating

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.


TO 3,5 MW

Robust Design.

HEC V1500 inverters offer a useful service life of more than 25 years’ operation in aggressive environments and under extreme weather conditions. Our HEC V1500 units 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.
