The first impression of the Centre 806 sound is a thick bottom, playing a large-scale symphony, with a rich sense of low-frequency volume, but the low-frequency dive ability is still insufficient, and the ability to form images cannot be Compared with the high-end goods in this review, playing fast-paced pop music is a bit disadvantageous. However, the good news is that the low frequency does not appear nervous under the sound pressure, it is more relaxed and natural, and the sense of speed is also good.
Generally speaking, the tone of the Centre 806 is slightly darkened, and the personality is not so lively. Although the sound field of the Centre 806 extends well in the horizontal and vertical directions, it has a little box sound, so it sounds sometimes It's a little boring, and it's a little opaque.
Industrial Energy Storage System
The main function of the Industrial Energy Storage System is to store energy in the industrial field to meet the energy demand in the industrial production process. It is an energy storage solution for improving energy efficiency and power supply stability in industrial production systems.
Main effect:
Energy peak shaving: Industrial energy storage systems can store energy and release energy at the peak of energy demand to meet the high energy consumption demand in the industrial production process. This helps to achieve a balanced deployment of energy and avoid energy waste or power outages caused by imbalances in energy supply and demand.
Reserve power supply: When the power supply of the power grid is unstable or there is a power outage, the industrial energy storage system can be used as a backup power supply to continue to supply the power required by industrial equipment and ensure the continuous operation of industrial production.
Energy saving and emission reduction: Through rational use of energy storage, industrial energy storage systems can optimize energy consumption and reduce energy waste, thereby achieving the goal of energy saving and emission reduction, and reducing the impact of industrial production on the environment.
Differences from other energy storage systems:
Scale and capacity: Industrial energy storage systems usually have large scale and energy storage capacity to meet the high energy demand in industrial production. Home energy storage systems, on the other hand, are usually smaller and are mainly used in home photovoltaic power generation systems.
Application scenarios: Industrial energy storage systems are mainly used in the industrial field to meet the energy demand in the industrial production process. The Home Energy Storage System is used in the home photovoltaic power generation system to improve the energy self-sufficiency of the home.
Control and management: Due to the large scale of industrial energy storage systems, their control and management require more complex and precise technical means to achieve efficient energy utilization and stable supply. Home energy storage systems are usually relatively simple and easier to automate and manage.
Generally speaking, the main function of industrial energy storage systems is to meet the energy demand in the process of industrial production, realize the balanced deployment of energy, and the stability of the power supply. Compared with home energy storage systems, it is different in terms of scale, capacity, application scenarios, and technical complexity.
