Domestic distributed generation (DG) concept is very hot, and PV as distributed generation of the most important forms of electricity generation is of concern, including photovoltaic inverter distributed photovoltaic power generation equipment, the quality of their products is good or bad a direct impact on the overall power generation efficiency of photovoltaic power plants and power generation. 

Solid ideal as a focus on solar photovoltaic inverter R & D, 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, PB bi-directional energy storage the six MT concentrated series of PV inverters, 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. 

Today, the the mainstream PV solar panel widely used in distributed power generation is divided into the following two: set of string inverters: generally refers to small power inverter output power 1kw to 20kW solid Dulwich SS Series 1.5 to 4.6 kW DS Series 3.6 to 4.6kW, DT Series 6 to 17kW centralized inverter: generally refers to output power greater than 100 kW high-power inverter solid Dulwich MT series, GW100k-MT, GW250k-MT, GW500k-MTL. 

In the design of a photovoltaic system, choose what kind of inverter (string & centralized), directly reflects the point of view of our system is designed to consider the issue: set of string inverters: the high degree of protection (solid Dulwich string inverter protection grade IP65), suitable for outdoor installation, save space, and more used in commercial roofing, and the pursuit of high power generation efficiency, high return on investment of small and medium-sized photovoltaic power plant project. The main feature is a single inverter, 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 through the practical application environment, the design of the two 1MW distributed photovoltaic power plants, the the program string type & central pure sine wave inverter system design as the core, to share with the customer the actual cost and operating results: 

Conclusion: String inverter W account for the price compared to centralized higher, but the entire system of cost accounting was essentially flat. String programs in the protection of the revenue, easy installation, repair and maintenance advantages of low cost, high security are very prominent. In particular, it is worth mentioning that a single failure of generating capacity is extremely obvious contrast. 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!
