Solid ideal for Artes 5 MW distributed photovoltaic power generation projects

April 28 solid Dulwich announced after the the Artes sun power companies strict factory audit, start using solid the Dulwich string inverter, the solid ideal officially became the PV inverter qualified supplier, in Suzhou 5MW distributed PV power plant construction, including: Suzhou New District Panasonic factory, Tongan Technology Park, factory to Long factory, EVA plant and Artes Changshu factory 5.

Distributed photovoltaic power generation become the development trend of the global photovoltaic solar panel manufacturers inverter is the key equipment of the system, the quality of their products direct impact on the overall power generation efficiency of photovoltaic power plants and power generation. At present, the the mainstream PV inverter widely used in distributed generation is divided into the following two: set of string inverters: generally refers to the output power 1kw to 20kW small power inverter with central inverters: Average refers to output power greater than 100kW high-power inverter. In the design of a photovoltaic system, choose what kind of inverter (string or centralized), reflecting the different design ideas, but also have different effects.

String inverter performance for the high degree of protection (solid Dulwich string inverter protection grade IP65), suitable for outdoor installation, save space, mostly used in commercial roof, and the pursuit of high power generation efficiency, high investment income of small and medium-sized photovoltaic power plant project. The main feature is that higher power generation efficiency, small size, light weight, easy installation, repair and maintenance costs low.

Central inverter: (protection class IP20) indoor installation, it normally takes to set up a dedicated power distribution room or outdoor room, and more used in the construction of large ground-based photovoltaic power plants, and has been widely used due to the low initial investment costs.

Solid Dulwich actual estimates, construction of string or central inverter a 1MW power plants, the overall costs were flat, but String inverter program multiple 10% of the electricity for the owners to bring greater investment income, the payback period is shorter.

It is understood that the solid Dulwich as a company focused on the research and development of solar cell photovoltaic inverter, production and sales of new energy high-tech enterprise, has now developed the production SS single-phase Single DS single-phase dual DT-phase dual DI high frequency isolation, ES bi-directional energy storage, JP Japanese models, MT concentrated photovoltaic inverter seven series products, power coverage 1.5kW to 500kW. Full range of photovoltaic inverter maximum conversion efficiency reached 98.8% MPP tracking efficiency of over 99.5%, the total current harmonic distortion (THDi) control in less than 1%, has reached world-class level.

Has developed a complete monitoring product line and wireless and Internet monitoring solutions to meet the diverse needs of different customers. Solid Dulwich, String inverter per watt account for the price compared to centralized high, but the cost of the entire system is basically the same. String programs in yield, ease of installation, maintenance, maintenance costs, high security advantages are very prominent. Selected group of string inverters for the MW level distributed power station construction, promotion distributed and the pursuit of higher investment income, is a big trend.
