SMA Increases its Edge in the PV Market with Acquisition of OKE Module Inverter Technology

SMA Solar Technology AG announces today the acquisition of the module inverters (micro-inverters) technology platform from the Dutch company OKE-Services. In the coming years, SMA will continue to develop this technology and launch its own module inverter product range.

Niestetal, Germany, September 3, 2009 - SMA Solar Technology AG announces today the acquisition of the module inverters (micro-inverters) technology platform from the Dutch company OKE-Services. In the coming years, SMA will continue to develop this technology and launch its own module inverter product range.

In order to expand its product portfolio in the lower range power classes and to meet all customer requirements in the future, SMA Solar Technology AG (SMA) has acquired the micro inverter technology platform from OKE-Services (OKE), a Dutch company. Both parties have agreed to keep the exact purchase price confidential. Unlike the photovoltaic inverter with string technology, which converts the direct current (DC) of numerous interconnected photovoltaic modules into alternating current (AC), a micro inverter converts the DC to AC separately at each individual photovoltaic module.

Micro-inverters are particularly well-suited for the use in small photovoltaic systems of 1 kWp or under. In some larger photovoltaic systems which use string inverters, shading of individual modules and the subsequently lower energy harvest of the entire system can be avoided by equipping and operating those modules with individual module inverters.

With the acquisition and further development of the OKE technology, SMA plans to launch its own range of module inverters in the coming years. This makes SMA the only manufacturer in the world with a product portfolio which includes all existing inverter technologies for operating photovoltaic systems of any size and with optimal technical system configuration. SMA customers will continue to profit from highest quality standards, a global sales and service network and short delivery times.

OKE is one of the pioneers of micro inverter technology and has more than 15 years\' experience in the development and series production of micro inverters. Based on this experience, OKE has continuously strived to optimize efficiency and specific price, both of which are particularly important parameters for the success of micro inverters. To this end, the company has systematically reduced the number of components used in their products, which is not only a prerequisite for a good price-performance ratio, but also ensures product reliability.

OMG Roofing Products - PowerGrip Universal

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
