Modern Converter Design

Based on the existing battery inverter portfolio, SMA developed an Electrolyzer Converter, that perfectly supports electrolyzer applications. The converter has a DC power range from 1 to 5 MW per unit. Bigger systems can be realized by parallel operation of the converters allowing a truly modular approach for maximum reliability. The design is based on a modular containerized solution, the so called MVPS (Medium Voltage Power Station). The MVPS is a fully integrated package, which is easy to transport and allows for high power densities. Moreover, it secures maximum flexibility at minimum costs and offers you a fully type-tested Power Conversion System with an excellent track record in many versatile applications.

Intelligent Grid- and Electrolyzer Management

SMA’s Electrolyser Converters are based on SMA’s well proven IGBT technology providing a wide range of advantages for the conversion of AC power into DC power. No additional harmonic filters or compensation units are necessary due to the very low harmonic distortion associated with SMA’s superior technology (THDi < 4%). The SMA converters are tested and certified according to state-of-the-art testing guidelines in order to fulfill all relevant national and international norms. The power factor can be adjusted across a wide range and the converter includes the latest grid codes of many countries.
The converter has a wide DC operation window for the electrolyzer operation. This enables us to work with most PEM and Alkaline Electrolyzers. Aging processes of the electrolyzer’s cells (degradation) are managed within our fully integrated system (e.g. increase of DC voltage over time) which allows a trouble-free operation with low maintenance over the whole lifetime of the electrolyzer.

PV-Diesel Hybrid Solutions

The Hybrid Controller (HyCon) represents a very flexible solution for medium and large solar hybrid plants (>100kW). HyCon allows direct coupling of renewable energy sources to gensets grids or to the public grid. The control system performs comprehensive grid management functions, ensures maximum operational safety and minimal operation expenditures.
In combination with the Sunny Central Storage, batteries can be included to stabilize the grid or provide ancillary grid services. Due to the optional grid forming function of the battery inverter, these off-grid systems can also run in a “diesel-off” mode, thus enabling a higher solar penetration. Black-start functionality allows starting the whole grid without any additional power from gensets.
