SOLAR INVERTERS

Solar inverters, sometimes called PV inverters, are a type of electrical inverter that is made to change the direct current (DC) electricity generated by a photovoltaic array into alternating current (AC) for use in a Smart utility grid or Micro Grid. As such, they are essential building blocks as developers look for more autonomy from centrallygenerated utility power.

A report jointly issued by the Fraunhofer Institute for Solar Energy Systems (ISE) and Bureau Veritas shows that AEG Power Solutions' Protect PV.250 solar inverter offers remarkable efficiency. Energy conversion efficiency testing conducted according to European Standard EN 50530 yielded a very high efficiency grade of 98.7%.

Energy conversion efficiency testing was conducted at eight different power levels, nine DC voltage levels and for two module technologies (thin film and crystalline technology, both used in solar farms). MPPT testing, performed by ISE according to the same European EN
50530 standard, yielded a Maximum Power Point (MPP) efficiency grade of 99.99%. ISE also reported that the PV.250 inverter, launched in Sept. 2009, successfully complied with EN 50530 dynamic requirements.

One of the first Protect PV.250 installed is part of the equipment of the solar farm of the city of Hungen in Germany. The performance of the solar park is considerably higher than had been forecast and which an efficiency study had calculated.

AEG Power Solutions is well positioned to fulfil all photovoltaic power plant requirements – today and in the future, in Europe, the US and elsewhere. With DC voltage capability up to 1000 V, the Protect PV.250 enables customers to achieve optimal power efficiency thanks to
its field-programmable gate array (FPGA) control system.

Specifically engineered to meet the requirements of utilitygrade applications, the Protect PV.250 can be customized to each application thanks to a range of available options and its unique design.
