PV poverty alleviation is a new way to help the poor and expand the PV market. It is conducive to increasing the income and employment of the people and changing the life style of the people. It has obvious industry driving and social benefits. The poverty alleviation projects of the PV system are mainly located in remote rural areas, where the actual situation is complex and changeable. The poverty alleviation projects are related to the image of the country and government. Therefore, strict requirements must be imposed on the inverters, which are the core components of the PV system.
The product quality must be very stable. The inverter may be installed in different places, so it may be exposed to harsh environments such as high temperature, severe cold, humidity, and dust. Therefore, the inverter company must have sufficient application experience to design the inverter.
2. In some rural areas, the electricity consumption is low in the daytime, but the solar energy is good in the daytime. If the user cannot digest the electricity, the electricity needs to be transmitted to the power grid. As a result, the voltage of the power grid increases. If the voltage is too high, the inverter may shut down or the user equipment may be damaged. This requires inverter companies to have the corresponding solutions, not only to generate electricity, but also not to damage the electrical equipment.
The electricity amount is the only revenue of PV power. Therefore, the inverter needs to generate as much electricity as possible. On the one hand, the inverter must have reliable performance and do not stop. On the other hand, the PV tracking MPPT technology must be good. On the other hand, the power generation range must be wide and the time must be long.
The PV anti-poverty project is also a national image project. The inverter is usually installed at home. Therefore, the inverter must be elegant in appearance. The SUN2000L-3KTL/5KTL, SUN2000-60KT-M0, and SUN2000-100KT-M0 series of grid-tied PV inverters launched by Huawei have made breakthroughs in performance improvement and are very suitable for residential PV plants.
The new inverter improves the product reliability, increases the energy yield, and enhances the user experience.
1. Improves product reliability, ensures high calculation accuracy, accelerates performance protection, improves product stability, reduces loss, and improves efficiency. Professional thermal design technology enables the SUN2000 to work properly even in harsh environments.
2.2. Increased energy yield: The energy yield of the inverter reflects the core value of the product. The new product uses the improved variable step-size MPPT tracking technology, which features high precision and fast dynamic response, and can adapt to rapid changes in sunlight and improve the energy yield efficiency. Ultra-low-power power generation: Long power generation time during the day increases the power generation revenue.
3.The new inverter has special technologies, such as connecting to the hosting cloud and working with Huawei SmartLogger to monitor data in real time. The SUN2000 is used in various regions around the world. Tens of thousands of SUN2000s have been delivered, and almost no fault occurs. Especially in the Guo Ning Xia, Shandong, Inner Mongolia, Liaoning, Shanxi, Anhui, and other poverty-relief areas, the new inverter has been highly appraised by multiple installation vendors due to its stable performance, high energy yield, and beautiful appearance, and has been selected as the first choice for inverter brands.
