Dr. Zhou introduced that Level 3 is a mature enterprise of global telecommunication operators that has been established for nearly 20 years since its establishment in 1997. During these years, Level 3 mainly serves enterprise users and operators, and it gradually found out more and more in 2000. The business, more biased towards video and CDN as an important part of Level3's products, video and CDN will also become a big element of Internet ecosystem services in the future. In the near future, how to handle video requirements through a new generation of IP networks and transfer them to customers will become an important challenge for the entire Internet. In 2007, Level 3 expanded its acquisition of Savvis's CDN business, catered to the explosive growth of multimedia requirements and combined it with a brand-new product. In addition, Level 3 was a special place that had its own global broadcast at the beginning of its establishment. Network (Vyyx Solutions), so Level 3 now integrates broadcasting with CDN to provide broadcasting customers with online and offline broadcast-level transmissions, and to distribute traditional broadcast programs to the CDN for dissemination via the Internet.
Dr. Zhou Lichong believes that although content providers today still come from broadcasting, this is only a traditional business. The challenge that all people face today is to be transmitted to the channel through the Internet. This has undergone many changes in the past few years. At present, the viewing habits of the audience are very different, and I often have content, but the audience is not only Simply accepting content from television, how to turn content into an OTT will be a huge challenge. After so many years of accumulation, the programs of the TV stations are not only simple and mature, but they are completely different from one TV broadcast to the Internet. Traditional TV stations will face enormous challenges. From 7:00 in the morning to 12 in the evening when watching TV. Points can all be different content, but they are completely different on the Internet. Audiences can be ordered on demand and they can choose their own favorite content. The Internet has not only changed the habit of our viewers watching TV, but has also changed the transmission of TV transmission TV programs. The habitual way to the audience.
There is another change in the business model. The traditional television business model is mainly advertising, watching an ad appear in fifteen minutes, but the Internet's advertising is different. Before you watch a program, you can see the ad, but not in the middle. There is advertising,. There are also other internet content providers that have different charging models. It may be difficult to immediately charge on television, but the Internet has a platform where you can charge. You can charge and the audience is willing to pay for premium content. If there is a company Making a good show can still earn income through the platform.
Level 3 has such an international platform, mainly in the Americas, Latin America, Europe, Asia, Europe, Africa and the Middle East. It uses its global IP network, gateway equipment and patented technology to provide users with the best services. Nodes quickly and reliably deliver content to all corners of the world, greatly improving the quality of user experience. In 2007, as Level3 entered the CDN era, it cooperated with domestic and foreign CDN manufacturers to form a CDN service gradually. Through this platform, it provided solutions to TV stations, through which traditional TVs could be transmitted via broadcast platforms, and traditional TVs could also be transmitted to the Internet. Transmitted to the viewer through the CDN.

The main function of the MPPT Solar Controller is to realize maximum power point tracking (MPPT) in the solar power generation system to improve the energy utilization efficiency of solar panels. It is an advanced charge controller that can adjust the output voltage and current of the Solar Panel in real-time to keep the solar panel operating at the maximum power output point.
Main effect:
Maximum power point tracking: MPPT Solar Controller can accurately calculate the maximum power output point of the solar panel by monitoring the voltage and current of the solar panel in real-time and according to the characteristics of the solar panel. It then adjusts the panel's output voltage and current to keep it operating at its maximum power output point, maximizing the solar panel's energy conversion efficiency.
High energy utilization rate: MPPT Solar Controller's maximum power point tracking function can ensure that the solar panel is always operating in the best working condition, making full use of solar energy, thereby improving the energy utilization rate of the photovoltaic power generation system.
Charge control: In addition to achieving maximum power point tracking, MPPT Solar Controller also has a charge control function to protect the battery from overcharge and over-discharge damage.
Differences from other charge controllers:
Maximum power point tracking function: MPPT Solar Controller is a charge controller specially used in solar power generation systems. The biggest difference is that it has a maximum power point tracking function, which is used to improve the energy conversion efficiency of solar panels. Other charge controllers may not have this unique feature.
Energy efficiency: MPPT Solar Controller can improve the energy efficiency of solar panels through maximum power point tracking technology. Other charge controllers may only be able to charge in a fixed manner and cannot achieve maximum power point tracking.
Application scenarios: MPPT Solar Controller is mainly used in solar power generation systems, while other charge controllers may be suitable for different types of energy generation systems, such as wind power, hydropower, etc.
Overall, the main role of the MPPT Solar Controller is to achieve maximum power point tracking, improve the energy conversion efficiency of the solar panel, and protect the battery from overcharge and over-discharge damage. Compared with other charge controllers, it has unique advantages in energy utilization efficiency and maximum power point tracking and is suitable for applications in solar power generation systems.
