Inverters for PV and energy storage solutions

Use of renewable energy sources is growing at a tremendous pace. A once static power generation landscape of large, central power plants is transitioning into a flexible, intelligent, and increasingly renewable distributed system. When it comes to state-of-the-art power grids, Siemens offers innovative solutions and comprehensive experience across the entire range of technology for solar photovoltaic systems.

String Inverter Architectures for Utility Scale Solar Projects webinar

Topics include:

  • Fraunhofer study: Comparison of single vs. multi-MPPT string inverter (mismatch, heterogeneous strings, interrow shading, installation angle/orientation, module variability)
  • Virtual central vs. distributed string architecture
  • Virtual central vs. true central inverters – pros/cons
  • High power “supersize” modules compatibility with string inverters.

Presented by Rudy Wodrich, Director of Photovoltaics for North America

Photovoltaic skids

  • Cost efficient design (easier transport than a containerized solution)
  • Open outdoor elements for efficient cooling and maximized cost reduction
  • Comprehensive “plug-and-play” solution for quick installation and commissioning
  • Highest power density for utility-scale PV plants

Central inverters:  a future-proof solution for large photovoltaic power plants 

The PV central inverter system is a convenient “plug-and play” solution with maximum power density combining inverter, transformer, and ring main unit. The central inverter offers an integrated DC/AC distribution for high efficiency.

Vector® series group-operated medium-voltage switches

Siemens medium-voltage air-break disconnect switches are designed for superior performance in three-phase loadbreak switching. 

SDR distribution medium-voltage reclosers

The SDR medium-voltage distribution recloser is a flexible outdoor vacuum switching device – pole or structure-mounted - that can trip and reclose up to nine times in case of a temporary line fault, thus avoiding longer network interruptions. The SDR offers reliable operation even in toughest climate conditions, like solar power plants.

8DJH 36 gas-insulated, arc-resistant, up to 38 kV switchgear

Medium-voltage 8DJH 36 switchgear is powerful and suitable for various distribution system applications. It can be used for energy supply at airports, train stations, stadiums, and large building complexes, such as hotels, banks, or hospitals. 8DJH 36’s advantages are ideal for renewable applications, particularly in onshore and offshore wind farms and in hydroelectric and solar power plants. Also, with an available outdoor enclosure, 8DJH 36 can fit into existing solar farm skid solutions with a transformer and inverter.

Siemens switchboards design has been aimed at improving layout convenience, reducing installation costs and minimizing the impact and cost of system changes. In addition, our environmentally friendly panelboard designs also simplify wiring and reduce material requirements, saving additional installation time.

Solar Investment Tax Credit

The Solar Investment Tax Credit (ITC) has been a widely successful policy attracting sizable tax-equity investment to drive the clean energy revolution in the United States. The ITC creates a great opportunity to optimize the financials of both distributed and utility-scale solar projects. Siemens has extensive experience with ITC Safe Harbor contracts for various eligible hardware including inverters, inverter stations, and other balance-of-plant equipment.


Over 20 GW of utility-scale solar are set to be installed each year for the next several years in the U.S. and the ITC is set to step down from 26% to 22% at the end of 2022.  To that end, developers and utilities interested in safe harboring electrical hardware at the 26% rate are encouraged to contact us early to ensure they secure capacity for deliveries in 2022 and early 2023.
