Product Overview
The photovoltaic industry is a rapidly developing field. With the increasing importance of renewable energy, photovoltaic power generation has attracted wide attention as a clean and sustainable energy. In the photovoltaic power generation system, the connector is one of the components that play a key role.
Advantages
QC Solar (301278) has launched QC4.10-PLUS connector, a high-performance product designed specifically for the photovoltaic industry. QC4.10-PLUS connector has successfully obtained the TUV 2000V photovoltaic system certification , which also means that this product has passed the 2 PfG 2925 / 01.23 standard.
QC4.10-PLUS connector adopts integrated design of the internal metal parts, making the installation process more simple and more convenient. It has less contact resistance and larger rated current, and can achieve ultra-low heat generation under the condition of high-power modules. This means QC4.10-PLUS connector can effectively eliminate the contact resistance and maximize the power generation efficiency of the photovoltaic panels.
The connector uses innovative designs and materials with excellent weather resistance, corrosion resistance and mechanical strength to enable stable operation in harsh environments. In addition, QC4.10-PLUS connector has a smaller overall size for narrower aluminum frames, saving up to 14 percent of aluminum. This not only increases the number of packaged panels, reduce material cost, but also decrease transportation cost. This is a very good news for the photovoltaic industry, as it helps to reduce production cost and improve corporate profitability.
QC4.10-PLUS connector is a cost-effective product provided by QC Solar (301278) for the photovoltaic industry. Its launch will facilitate the industry into the era of "zero contact resistance", bring more efficient, reliable and economical connection solutions for photovoltaic power generation systems, and promote the sustainable development of the photovoltaic industry.
