Statistics, China's domestic inverter manufacturers more than one hundred, larger than 5MW at least 50 companies are also. However, the top ten vendors, its shipments accounted for more than 70% market share. Of future market trends and technology trends to grasp, is believed to significantly alter the inverters in the market.

According to IMS Research PV market for emerging Observation 2013 - 2017, the domestic and above will continue to 500kW central inverters for the mainstream. But with the country's support for distributed PV implement centralized ,30-250kW inverter shipments may also be expanded.

The industry generally believe that in Europe, will continue to be small power inverters, mainly in China, places more than 250kW inverter based.

Xie Feng told reporters that the current European market has emerged for multiple MPPT of <= 5kw string inverter needs. The next two to three years, will also be used around the world indoor rooftop PV systems see more storage systems.

Chinese companies Fronius Solar Electronics Division Director Li Yun that because micro-inverter high cost per watt defect exists, the next few years, its market share will be more than the power optimizer.

According to reports, the inverter is different from the assembly of electronic products belong, in order to achieve the desired quality and conversion rates, the internal components selection also appears to be crucial, which is to ensure the stability of the product.

Insiders told reporters that high-quality hardware is important, but decided inverter performance in addition to the hardware, the software side is also particularly important, for example, structural design, algorithm optimization. Thus, with hardware, assembly inverter is not difficult, but the inverter is the core competitiveness of enterprise software side of its strength.

Xie Feng said that as the installed capacity expansion and technological progress, market competition and other factors, the average price is expected to inverter will maintain a sustained downward trend. If the discussion cost of the inverter, the indoor roof systems with terrestrial systems with the inverter in a different proportion. In conjunction with the specific system solutions will know what the project uses an inverter to calculate the PV DC TO ACsystem costs accounted for the proportion.

An inverter manufacturers responsible person told the reporter, PV inverter PV systems as the core power conditioning devices, in general, occupy system cost ratio of 10% -15%.

"Inverters for photovoltaic systems of more reflected in the grid connection terminal for household systems investors (usually the owner himself or community managers) and small commercial power plant investors (usually industrial users), the overall After the system and network power generation efficiency is more important, that the average output of PV systems, trouble-free operation time and the flexibility to adapt to the requirements of grid load shifting ability. "Xie Feng said.
