Product Briefing Outline: Siemens AG has developed and manufactured inverters for photovoltaic applications since 1987. The latest products of this development are the SINVERT PV inverters, a family of three phase grid-connected inverters in the range of 60kVA up to 1700kVA. They already serve as central inverters in a large number of PV power plants. In Siemens’ SINVERT 1700 MS, four units of 420kVA act as a single 1.7MVA PV inverter. The combination of up to four single inverters working together maximizes performance, yield and availability.

Problem: Operators, investors and project planners need a PV power plant that
requires a minimum of maintenance care. Less service labour and down-times
mean less cost reduction in the return on investment. Only the most reliable and
field-proven components, such as modules and their mounting structures, cabling and
combiner boxes as well as the inverters with their containers and the whole medium
voltage equipment are desired. To control these complex power plants, an industrial-grade supervision system is necessary.

Solution: Equipped with features like master slave operation, symmetry monitoring and VAr control, Siemens’ SINVERT covers the current and future recommendations
of a reliable and almost maintenance-free operation. Providing superior performance
ratio, SINVERT makes the best of the power the solar panel can generate.

Applications: Grid-connected PV installations, such as fixed and tracking field
installations and BIPV installations.

Platform: Standard Siemens drive inverters from the MASTERDRIVES and SINAMICS series, which are certified by all applicable standards. Using these high performance drives, Siemens delivers PV inverters in cabinets of two sizes, 2000 x 2700 x 800mm and 1902 x 918 x 834mm. Transportation is easy due to the separate transformer cabinet. Pre- configured concrete containers are also available.

Availability: Available now.
