2013 , micro inverter shipments is likely to first break 500MW, however , in terms of price competition , suppliers will also face many challenges. The face of the enormous potential of emerging markets, many suppliers have introduced new products , SMA and Power-One is one of two large photovoltaic inverter manufacturer. 2013 , inverter market competition will be very intense, micro-inverter prices are likely to fall 16%.

Although the 2013 micro- inverters to achieve double-digit percentage decline in prices , but the rapid growth in shipments of its total revenue gains may still be more than 250 million U.S. dollars . However , micro-inverter prices in the coming years will continue to decline. IHS predicts that total global micro-inverter market revenue will reach $ 700 million in 2017.

EnphaseEnergy as the world 's leading suppliers of micro inverters , residential PV market in the U.S. last year, the largest share . However, as other micro-inverter increasing number of suppliers , the enterprises are facing increasingly fierce competition . Therefore , Enphase and other suppliers have Dingzhun new markets , and actively promote the development of micro- inverter systems in the commercial sector , in order to further expand its market share.

Enphase strategy pursued now has a growing signs of success . Recently, the company announced the installation of 2.3 megawatts of solar projects in Canada supply micro- inverter. Third of the world 's micro-off grid inverter shipments in 2017 will be included in the Business Systems Division , while in 2012 this figure was only 9%. In addition, in 2017 , the vast majority of micro-inverter will be used to scale for the 10-100kW systems.

National Energy Partner selection Chint Power Systems 20kW three-phase string inverter type for the ten school supply.

October 2013 , Chint power and intention to reach the customer , will be in New Jersey offers more than 300 solar projects of 20kW inverter. These projects include a variety of applications, the group of string PV inverter with a flexible architecture to adapt advantages: an inverter designed to meet the same roof , garage or even tens of thousands of ground kW power plant needs.

Chint 20kW platform independent testing laboratory through PHOTON and November 2011 in the other competing brands were rated as " one of the top ten inverters ." The product is 600V DC Input, Dual MPPT design , and with integrated fuse, DC and AC switch junction box. 2013 , Chint Power Systems has developed a new generation of 14kW and 23/28kW1000V DC input of the inverter , the products have passed UL certification, and has been to invest in the market .

National Energy Partners LLC, COO LouSabec representation , said: " Chint is a superb company, it gives us these projects provides the most cost-effective solution . Chint wind inverter applications through flexible and the lowest installed cost to enhance the economics of our projects . "

Chint Power Systems Americas, sales and marketing, general manager, said : "We are delighted NEP chose Chint Power Systems America branch , and we are looking forward to throughout the project life cycle are to maintain cooperative relations , including design , delivery, installation and on-site services .

Built on the roof of a small photovoltaic power plants, both to achieve self-sufficiency in power supply, but also to make money. This is Wang Qingwang dream for many years. Today, his dream come true, and built the first grid Liaocheng household photovoltaic power plants.

Wang Qingwang household photovoltaic plant in Yanggu County Lion Village street waiting on the roof of a three-tier general by 12 photovoltaic solar panels, an wind inverter a power meter and switches, wires and other components, covering about 20 square meters, with a total cost of around $ 30,000.

3 kilowatts installed capacity of power plants, is expected to generate electricity 4000 kwh, Wang Qingwang of household electricity consumption is generally about 4 degrees per day, the excess electricity transported through the metering meter to the national grid. According to the current national policies to 0.47 yuan per kilowatt plus the proceeds of selling electricity per kWh countries fa 1 0.42 yuan subsidy calculation, about 10 years will be able to recover the cost of equipment, and the entire family system PV power plant in 25 years of life above, the remaining ten years is pure benefit.

After a month of trial operation, Wang Qingwang household photovoltaic http://www.gridtiepowerinverteronline.com/ power plant has successfully passed the acceptance into the national grid, which marks the first self Liaocheng photovoltaic power generation and network success. "I built this plant starting point, is trying to take advantage of idle roof up to the current popularity of ordinary households. Photovoltaic power plant per kilowatt, you can save a kilowatt of coal consumption, environmental protection is very useful." Wangqing Wang said, This power generation, not only self-sufficiency can be fully realized power, and is a real clean energy without any pollution.

Jiangsu solid Dulwich recently announced two weeks after the company 's rigorous investigation can determine the inverter in the UK do not exist in the recent storms damaged and non- functioning of the possibilities.

According to reports, southeast England suffered the strongest storm in 26 years , there are more than 600,000 families have been the impact of power outages .

Solid Dulwich staff focus on investigation of Kent, Kangwo other county families and outdoor photovoltaic micro grid tie inverter system operation , learned through the sales order , which is located in the British East county farm inverter PV power plant is operating normally , has been installed since September , the total generating capacity of the plant has more than 20000kW / h, 15% higher than expected .

Dual solid -phase off grid inverter Dulwich (DT series ) used in the United Kingdom Gloucestershire farm Dulwich photovoltaic power plant solid technical support and service center responsible person JefferyWong said the company is dealing with the natural disaster warning temporary initiated 24 hours measures , designed to provide local customer support and service convenience. After two weeks of rigorous investigation and return customers , the company has not received any non- normal operation of the inverter case reports .

Recently, the Ninth CSPV seminar, Certification Center announced the current specific aspects of work carried out , including " China inverter efficiency ' work has entered the final review stage .

" Efficiency Inverter China " is similar to the efficiency of California , or the European efficiency. Efficiency of California is different, because China's vast land , and much larger than California , therefore, according to the division of Chinese solar subsidies three regions , each region has a different price subsidies , according to these three regions typical solar energy resources and develop the efficiency of the off grid inverter China , " China inverter efficiency " will provide different types of products in China inverter efficiency is the number of different regions .

It is understood that " the efficiency of the inverter China " could end of this month there will be a lot of progress . "Inverter China efficiency" is based on a research project to develop a technical specification , like the National Administration of the inverter has filed a technical specification . The technical specifications of the test formulation requires matching capabilities, including high-power PPS, square analog sources , etc., but CGC is located in South China, East China , Central China and North China, supporting laboratory test equipment are already in place , is currently in the commissioning phase .

Reportedly, the technical specification has entered the final review stage , if they can pass the review , this specification will be able to launch it early . With the introduction of the technical specifications , the inverter with charger will increase a new logo, to achieve " scientific standardization, logo mark of " objective. The technical specifications will be developed very successful domestic cases .
