Problems solved by technology

[0002] With the worldwide shortage of petrochemical energy, the utilization of renewable energy has attracted worldwide attention. Among them, solar energy and wind energy are the most common renewable new energy sources. The biggest feature is that they are inexhaustible and ubiquitous! Now there are mature technologies for generating electricity from these renewable energies, which usually use centralized power generation and are transmitted to the user end by merging into the traditional power transmission and transformation grid. However, due to the use of a large number of batteries, power transmission and transformation Equipment, high construction cost
[0003] At present, there is no technology in the world that uses these most common and widely distributed decentralized energy sources to generate electricity on-site, without passing through traditional power transmission and transformation, and to supply electricity to users who are also distributed locally.
