New SolarMax outdoor solution for large-scale plants

Popular Articles

The new SolarMax 360 TS-SV central inverter and the TS-SV Compact Station, with a rated output power of 720kW, are, together, a cost effective complete solution for large PV power plants.

The first 38MW project is currently already being realized.

Biel, February 26th, 2013: The Swiss inverter manufacturer Sputnik Engineering presents a new version of the tried and tested 330TS-SV inverter: the SolarMax central inverter 360TS-SV. Thanks to an increased minimum input voltage and greater output voltage, the 360TS-SV is able to provide a rated output power which is 30kW higher than that of the 330TS-SV. Two 360TS-SVs can be installed easily, in a time and cost effective manner, on site using the new TS-SV Compact Station whose weight is significantly lower than that of a conventional concrete station. In this specification a 720TS-SV Compact Station provides a rated output power of 720kW. However, the station is also available as 660TS-SV Compact Station with two 330TS-SV inverters and a rated output power of 660kW.

Easy outdoor installation and flexible use
The TS-SV Compact Station has a compact housing and is provided to the plant manufacturer as a turn-key solution. With a total weight of less than three tons, the TS-SV Compact Station is easy to install and transport. Thanks to the rust-protected cable entry tray, a concrete foundation is not necessary. Two of these stations can be connected to the medium voltage mains via a plug&play facility using a compact transformer station.

Just like the 330TS-SV, the new 360TS-SV inverter also impresses with its flexible application options. Thanks to the modular design of the TS-SV series, it is possible to control and monitor up to four inverters or 1.44MW via a superior control and operating unit (Master Control Unit).

Optimum yield
The 360TS-SV consists of three Power Units (each with 120kW) and can be operated either with one MPP tracker (single MPPT with partial-load optimization and error management) or with three independent MPP trackers (multi MPPT). The former is suitable for PV power plants with a homogeneous module array and limited shadowing. If the plant consists of different types of surfaces or if a part of the solar generator is shaded, three trackers in multi MPPT operation optimize the yield.

“We have optimized the parameters of the new 360TS-SV central inverter so as to achieve a higher rated output power. This means that fewer inverter stations are needed for the construction of a ground-mounted plant with megawatt capability resulting in reduced overall costs,” explains Beat Greber, Senior Product Manager for SolarMax central inverters. “In addition, the lower levels of AC current result in fewer losses which increases the efficiency of the inverters. The 360TS-SV has a European Efficiency of 97.4 percent. Combined with the new TS-SV Compact Station we provide a complete outdoor solution with an attractive price/performance ratio which can be installed quickly and easily.”

A first project, of 38MW, is currently already being realized in United Kingdom. A total of 31 x 720TS-SV and 14 x 660TS-SV Compact Stations will be installed. In April, another 3.4MW project will be realized in Switzerland.

Like the entire SolarMax product range, the TS-SV Compact Station and the 360TS-SV are reliable Swiss quality products and secure the long-term and trouble-free operation of each plant. They will be available as of spring 2013.

About SolarMax
Sputnik Engineering AG, a Swiss company, is one of the world’s leading manufacturers of grid-connected solar inverters. Under the name SolarMax the company develops, produces and sells inverters for every system – from photovoltaic plants on single-family homes whose kilowatt output is modest, to the solar power plants whose output is measured in megawatts. The inverter is a key component of the solar plant, transforming the generated direct current into grid-compliant alternating current. 20 years of experience are not only reflected in the Swiss quality, highest efficiency, reliability, and durability of the SolarMax products, but also in the way Sputnik offers its customers excellent international support in the field of after sales, comprehensive warranty services, and intelligent solutions for system monitoring.

SolarMax is positioned internationally and currently has approx. 360 employees. The company headquarters are located in Switzerland (Biel), products are sold and distributed via the branches in Germany, Spain, Italy, France, China, Belgium, United Kingdom, Greece, Bulgaria and Australia.
