Mitsubishi Electric Announces Photovoltaic Inverter for European Market.TOKYO -- Mitsubishi Electric Mitsubishi Electric Corporation (三菱電機株式会社 Corporation (TOKYO:6503) (President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. : Setsuhiro Shimomura) announced today it will introduce 2 models of photovoltaic inverters A photovoltaic inverter changes direct current (DC) from a solar cell array to alternating current (AC), synchronizes with a grid and feeds the energy into the grid, mostly a public utility grid. to the European market on September 1st. The inverters, which convert the DC current from solar cells solar cell, semiconductor devised to convert light to electric current. It is a specially constructed diode, usually made of silicon crystal. When light strikes the exposed active surface, it knocks electrons loose from their sites in the crystal. to AC for power grid use, have one of the highest conversion efficiency (Max. 96.2%) and input voltage (Max. 700V) ratings in the industry, and will be displayed at the Intersolar 2006 exhibition in Freiberg, Germany, Europe's largest solar products trade fair, starting June 22.

Aim of Sale Europe is the largest market in the world for photovoltaic The generation of voltage by a material that is exposed to light in the visible and invisible ranges. See photoelectric and photovoltaic cell. power generation systems, and continues to grow at an annual rate of about 50%. This is due in part to the rapid expansion caused by Germany's new Feed-in Tariff A Feed-in Tariff (FiT, FiL, Feed-in Law or Solar Premium) is an incentive structure that boosts the adoption of renewable energy through government legislation. The regional or national electricity utilities are obligated to buy ‘green’ electricity (electricity subsidy system and other similar systems established in Spain and Italy. In its 25 years of business history in Japan and recent market research on the European market, Mitsubishi Electric Corporation will be the first Japanese manufacturer to launch independently developed and manufactured photovoltaic inverters to the European market, we expect stable growth and aim to strengthen our photovoltaic power generation system business in the world's largest market. The new products are similar to the safe, high efficiency, high reliability models produced for the Japanese domestic market The Japanese domestic market (JDM) describes the trade mechanisms solely within Japan, including imports and exports. The term Japanese domestic market, more often used as the acronym JDM rather than the full term, may also refer to a style of modifying automobiles and a . Sales will begin initially with indoor installation types, and then expand into other areas like outdoor installations, etc. Special features of new products 1. One of the industry's highest conversion efficiency (max. 96.2%). We have developed a new power module mounted photovoltaic inverter for the European market. The internal circuitry uses a new 3-level inverter (1) A logic gate that converts the input to the opposite state for output. If the input is true, the output is false, and vice versa. An inverter performs the Boolean logic NOT operation. (2) A circuit that converts DC current into AC current. Contrast with rectifier. system(1) (patent pending), as well as a high output low-loss new ferrite core ferrite core n. A magnetic core used in a computer core memory. material reactor filter to adjust electric current waveform The shape of a signal. See wavelength, sine wave and square wave. , all allowing for optimal control and high conversion efficiency. (1) reduces loss from switching between high, mid, and low potential 2. One of the industry's highest input voltage (max. 700V) We achieved one of the industries highest input voltages by using a newly developed input circuitry (patent pending) to minimize reduced conversion efficiency from high input voltage. Responses to high input voltage can make reduction in numbers in numbered parts; as, a book published in numbers. See also: Number of input strings, increasing the numbers of modules in series per one string, and improve the installation work. 3. Long term reliability using newly developed cooling and clean structure Dust from cooling fans used to cool circuit boards has reduced the reliability of previous photovoltaic inverters. In this new inverter, we've mounted a temperature control fan that runs only when and where it is needed. This newly developed construction works only as a heat dissipation Noun 1. heat dissipation - dissipation of heat chilling, cooling, temperature reduction - the process of becoming cooler; a falling temperature fan, and does not blow air onto the circuit board, blocking excessive flow to the circuit board. This maintains cleanliness Cleanliness See also Orderliness. Cleverness (See CUNNING.) Berchta unkempt herself, demands cleanliness from others, especially children. [Ger. Folklore: Leach, 137] cat continually “washes” itself. in the circuit board section, giving the inverter superb and long lasting reliability. This structure can also operate in a wide temperature range of -25 degrees C to +60 degrees C fit for strict European installation conditions such as basements. Other features of new products 1. High MPPT MPPT Maximum Power Point Tracking (space power regulator topology) efficiency of 99.7% The amount of electricity from solar modules are fed to the grid depends on conversion efficiency and the Maximum Power Point Tracking (MPPT) efficiency. We realized a MPPT efficiency of 99.7% with almost no loss by developing new software that controls the solar module to its maximum operating point. 2. Long-term reliability using original derating Derating is the technique employed in power electrical and electronic devices wherein the devices are operated at less than their rated maximum power dissipation taking into consideration the case/body temperature, ambient temperature and the type of cooling mechanism used. design concept There are more than a thousand electric devices in a photovoltaic inverter. We were able to reduce the number of electric parts and secure long-term reliability by using a derating design concept. All electronic parts of the inverter are value rated so it can be used with less operating parameters. 3. High safety and easy installation using internal terminal block connection Based on many years of experience, Mitsubishi Electric uses a terminal block connecting method inside the photovoltaic inverter for connecting the cable from the solar module with the inverter, enhancing irrefragability ir·ref·ra·ga·ble adj.

High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to to solar modules over extended periods of time. Mitsubishi Electric adopts metal enclosed housing structure that improves fireproofing fireproofing, method of making normally combustible materials as nearly noncombustible as possible. Fireproofing generally applies to textiles and construction materials that are treated with a solution or coating of some substance that will tend to retard their of the inverter. 5. Lightweight 19 kg wall mounting unit simplifies installation We were able to reduce the size and weight of the inverter due to high conversion efficiency. The inverter can be wall mounted, easing and simplifying installation. 6. Increased internal temperature control in parallel installation using asymmetrical a·sym·met·ri·cal or a·sym·met·ric adj.
