An earthquake of magnitude 8 occurred in Wenchuan, Sichuan Province. This sudden disaster has buried a lot of fresh lives and shocked the hearts of every Chinese! In the face of natural disasters, the world has its own great love! In the craze of the nation’s people’s efforts to fight the earthquake and disaster relief, Thousands of employees of Shangguang also extended their friendly hands, dedicated a sincere love, and made their own meager strength to help the people in the disaster areas rebuild their homes.

A major earthquake occurred in Wenchuan County, Sichuan Province on May 12, 2008
At about 2 pm on May 12, 2008, a magnitude 7.8 earthquake occurred in Wenchuan County, Sichuan Province. The earthquake was strong and involved, and many counties and cities such as Wenchuan, Mianyang, Deyang and Beichuan in Sichuan suffered heavy losses. How many roads were broken, how many houses collapsed, and how many lives were buried. People’s lives and property were greatly damaged. After the disaster occurred, the Party Central Committee and the State Council attached great importance to this and demanded that all localities and departments resolutely implement the Party Central Committee's earthquake relief and deployment, extensively mobilize all social forces, unite and cooperate, fully support, and resolutely defeat the hardship of earthquake relief.
On May 13, 2008, one party has difficulty supporting all parties.
The Wenchuan Earthquake in Sichuan has touched the hearts of the people of the whole country. The whole country has been working hard to support the disaster relief work in different forms. While diligently expressing sympathy for the people in the disaster area, the diligent employees carried forward the traditional virtues of one party's difficulties and support from all sides, spontaneously organized donations and donations to the people in the disaster areas, and quickly launched the companywide. On May 13th, the Ministry of Brand Culture and the Ministry of Human Resources planned to hold a large-scale fundraising event, and issued an initiative to the whole company, calling on all employees to extend a friendly hand, pass on a love, donate a love, and donate to our diligent people. A piece of love to help the people in the disaster area overcome the disaster. The leaders of the company gave great affirmation to this and demanded that the fundraising activities be organized. The charity and love items should be handed over to the people in the disaster area as soon as possible, so that they can feel the people of the country together with them, the diligent people and they are together.
On May 15th, 2008, the love situation in Wenchuan disaster area was diligent.
On May 15th, the Human Rights Department and the Brand Culture Department jointly organized the fund-raising activities of the people in the disaster area in the company office building plaza. They received enthusiastic response and support from all the staff of the company, and also received the attention of the government. The news media conducted live interviews and television broadcasts. Many employees, despite their shame, expressed their willingness to do their best to help them in the disaster areas. They also spontaneously organize and mobilize other employees to donate money and materials. Everyone, you fifty, I donate a hundred yuan to donate money, showing the spirit of the diligent person, reflecting the great and unselfish love of diligence.

Love illuminates the disaster area, the truth is warm and warm, and the people on the heart and the disaster-stricken area have received very good results, and they have won unanimous praise from all walks of life. The family members of the employees and the residents nearby also heard the news and consciously joined the ranks of the donations, showing their true concern for supporting the disaster area. The company also plans to donate hundreds of thousands of yuan of high-power LED street light products and solar energy products to help people in the disaster areas rebuild their homes. In addition, the fundraising activities of the company headquarters, Hengli and Liaobu branch are still in progress.

The main function of the PWM Solar Controller is to manage the charging and discharging process between solar panels and batteries in solar power generation systems. It is a traditional charge controller that controls the charging voltage and current through pulse width modulation technology to maintain the charging state of the battery and protect the battery.
Main effect:
Charging control: PWM Solar Controller controls the charging voltage and current through pulse width modulation technology to ensure that the battery is charged at an appropriate voltage and current to prolong the service life of the battery.
Overcharge protection: The PWM Solar Controller can monitor the charging status of the battery, and when the battery is fully charged, it will automatically stop charging to avoid battery damage caused by overcharging.
Over-discharge protection: PWM Solar Controller can monitor the discharge state of the battery. When the battery power is lower than a certain level, it will automatically stop discharging to avoid battery damage caused by over-discharge.
Differences from other charge controllers:
Modulation technology: PWM Solar Controller uses pulse width modulation technology to control the charging and discharging voltage and current to maintain the charging state of the battery. In contrast, MPPT Solar Controller uses maximum power point tracking technology to adjust the output voltage and current of solar panels in real-time to achieve maximum power output.
Energy conversion efficiency: Compared with the MPPT Solar Controller, the energy conversion efficiency of the PWM Solar Controller is lower. Because the pulse width modulation technology cannot adjust the operating point of the Solar Panel in real-time, the output power of the solar panel may not be maximized.
Application Scenario: PWM Solar Controller is a traditional charge controller suitable for small-scale, low-power solar power generation systems. The MPPT Solar Controller is suitable for larger-scale, high-power solar power generation systems to improve energy utilization efficiency.
Overall, the main role of the PWM Solar Controller is to manage the charging and discharging process in the solar power generation system and protect the battery from damage. Compared with MPPT Solar Controller, it uses traditional pulse width modulation technology, and the energy conversion efficiency is lower. Suitable for small-scale, low-power solar power generation systems. The MPPT Solar Controller uses maximum power point tracking technology, which can improve the energy utilization efficiency of solar panels, and is suitable for larger-scale, high-power solar power generation systems.
