Inverter quality problems exist, photovoltaic power plants, or after five years on major issues will highlight

Visited a number of power stations and many inverter companies, and more deeply understand, Chinese enterprises in the development of the inverter on the road, relying on industry and scale, both in the international community have an unparalleled advantage. PV power plant construction is a systematic project, the inverter is one of the core power devices. However, key parts of the core of the device, he was chief engineer of several inverter companies questioned.

Ups inverter on the market the vast majority of resistors and capacitors, and resistors and capacitors are not ideal, will lead to instability of the inverter performance and service life shortened. If the pure sine wave power inverter is connected in parallel, generating capacity will become increasingly smaller, machine downtime; For tandem structure will result in an explosion. There is only SMA, Siemens thin-film capacitors, China TBEA used only film capacitors, stable performance and long service life up to 25 years, however, the cost is 15% higher than the resistance and capacitance.

There are many industry insiders believe that film capacitors in 2012 the new, high-power device application time is even shorter, while electrolytic capacitors have decades of history, in the application in terms of the absolute is mature.

In addition, UPS inverter http://www.gridtiepowerinverteronline.com/ voltage across the performance is not very good in addition to, but also more delicate, more suitable for the temperature pleasant air-conditioned rooms, however, place the inverter room temperature often reaches 40 to 50 degrees, in terms of its is a big challenge. Many domestic inverter manufacturers, intense competition, the manufacturers in order to occupy a place in the market, playing the price war, in pursuit of profits, many companies exaggerate the wattage, and cut corners.
