Power Electronics - Model HEM - Ultimate Medium-Voltage Inverter

1. EASY MAINTENANCE
The advantages of a central inverter with the modularity of the string inverters.

Designed to be easily replaceable on the field with a safe, reliable, and fast Plug&Play assembly system. Includes up to 4 FRUs (field replaceable units).

2. BUS PLUS

Combine solar and storage.

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.

3. ECON MODE
Disconnecting the power station from the grid and taking the medium-voltage transformer out of the circuit, eliminating the continuous energy cost of no-load losses.

4. ADVANCED GRID
Capable of operating on any power system, offering advanced grid support functionalities like fast frequency response and synthetic inertia among others.

5. ICOOL 3
The most innovative cooling system. Our own air ventilation system provides a constant flow of clean air inside the equipment, without the need of liquid cooling

6. 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.

7. 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).
