March 19 news, has been the news of the telecommunications version of Nokia Lumia800 confirmed will be released on the 28th of this month, officially listed in April sales. It is reported that this product will be distributed by Tianyi Terminal Corporation for centralized collection and distribution. China Telecom will give a substantial subsidy, and the lowest price of the contract package is only 19 yuan. Telecommunications releases first to be launched in April
It is understood that the Lumia series of smart phones equipped with WindowsPhone7.5 operating system, the initial introduction of CDMA and WCDMA two versions, so the corresponding cooperation operators will be China Telecom and China Unicom.
According to sources, China Telecom will join hands with Nokia to release the first three WP phones in Beijing on March 28. The official time for the launch will be April.
In terms of configuration, the telecom Lumia800 will be equipped with a Windows Phone 7.5 OS, a 3.7-inch AMOLED screen, and a 1.4GHz Qualcomm Snapdragon Snapdragon MSM8655 processor. With 8 million pixel camera, support auto focus, touch focus, dual LED flash and 720p HD video recording and so on. The integrated polycarbonate design will also include applications such as Love Music, Tianyi Broadband and many other China Telecom Tianyi businesses, as well as Nokia Maps.
Tianyi Terminal Company unified collection mining
According to an insider of China Telecom, after negotiating with Nokia, they decided to adopt the principle of high and low collocation. The three mobile phones introduced were Lumia800C, Lumia719C and Lumia610. In terms of sales prices, the three bare metal mobile phone prices were: 3899 yuan, 2899 yuan and 1899 yuan. At the same time, as a collector and collector model, China Telecom will also increase its subsidies, and the minimum package price of this machine is only 19 yuan.
It is also known that this product will be collected by Tianyi Terminal Co., Ltd., and the provincial Tianyi Terminal will be distributed to agents. At present, China Telecom and Nokia headquarters are discussing the listing plan for this product. Nokia also prepared a corresponding retail market sales plan for China Telecom's operating outlets, which were mainly divided into outdoor images, indoor displays, and real machine demonstration areas.
Equipped with Microsoft to expand the Chinese market
According to statistics, Nokia's Lumia series of smart phones have been sold in some countries or regions in the world, but they have not been sold synchronously in the Chinese market. In the past MWC2012, Nokia began to announce that the Lumia series of smart phones will enter the Chinese market in April this year. Industry insiders believe that Nokia is taking Microsoft to China and intends to use the Windows Phone to regain a game in the contest with Apple and Google.
It is reported that on the first day of iPhone4S China’s opening of sales, there was confusion in Apple retail stores in Beijing and Shanghai. In response, Apple CEO Tim Cook stated that Apple underestimated the demand for iPhone4S in the Chinese market. Apple spokeswoman Carolyn Wu also said that the iPhone 4S has caused an "unbelievable response" among consumers worldwide, and that Apple "can't wait to make more Chinese consumers get the iPhone 4S."
On March 9, China Telecom has also begun to officially sell iPhone4S in China.
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.
