Siemens Industrial Automation Group launched a grand for a new medium-sized photovoltaic power plants Sinvert PVS grid PV inverter series. Currently, the new series, which provides three-phase transformerless inverter products, the rated output power of up to 500,1000,1500,2000 KW, efficiency up to 98.4%. 2MW inverter output power is currently the highest on the market without transformer products. Siemens' new high efficiency inverter, making use of medium voltage grid ground or large roof-mounted photovoltaic power plant can get higher returns.

Siemens can also provide new Sinvert PVS contain compact central inverter and medium voltage devices and other ancillary equipment containerized electrical room. The inverter will be the first time in Shanghai SNEC exhibition booth Siemens Hall E4.350 published. More efficient than the previous generation has greatly improved, allowing customers to be able to run the entire cycle of PV systems to achieve higher returns. The main - not only from the technical devices to achieve higher availability and access to a longer service life. Further, since the wind inverter unit according to the intensity of solar radiation into and out, so that the efficiency of a separate system than higher.

Therefore, the efficiency of solar power is greatly optimized, especially in the case of low load operation: even at low solar radiation, the system can be started, and even in the low power range can achieve high conversion efficiency. Because inverter technology with intelligent master-slave control, always choose the shortest running time unit first put into use, the running time of the inverter unit all basically the same, so that greatly increased the plant's service life.

New Sinvert PVS inverter series can easily pass the standard communication interface, integrated in the SCADA system. modified sine wave inverter native integrated graphic display with touch function to ensure user-friendly operator interface and system performance in situ data visualization services. New device complies with the German Association of Energy and Industry Guidelines for the medium voltage system requirements, including low voltage ride through FRT (Fault Ride Through) and active control of all the requirements.
