UPS (Uninterruptible Power System), that is, uninterruptible power supply, is an uninterruptible power supply containing energy storage device with constant voltage and frequency with the inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment.

Solar energy is the light, heat and other forms of rays that travel 150 million kilometers of space to Earth. We rely on new technologies to harness this energy to generate electricity and drive machines. Solar energy is even the most important energy source, as other energy sources such as coal, oil, wind and water come from solar energy.

Refers to a device containing an electrolyte solution and a metal electrode to generate an electric current in a cup, tank or other container or composite container part of the space that can convert chemical energy into electrical energy. It has a positive pole and a negative pole. With the advancement of science and technology, batteries generally refer to small devices that can generate electricity. Such as solar cells.

AVR voltage regulators are widely used in computers, test equipment, lighting systems, communication systems, medical equipment, industrial automation equipment, audio equipment and other power places, and are an ideal stabilized power supply.
