As energy transformation continues to intensify, energy internet has become the common direction of energy system development in various countries. As a key technology supporting energy internet, energy storage has been widely used in large-scale industrial and commercial high-energy-consuming units such as smart cities, industrial parks, community business districts, and commercial office buildings, realizing intelligent energy management.

The smart home energy storage system adopts an integrated home appliance design, is exquisite and beautiful, and is easy to install. It can supply electricity to residences, public facilities, small factories, etc. The home energy storage system uses rooftop solar power generation devices, household wind turbines to generate energy, and low-cost electricity sources from the social power supply system to store surplus electricity in the energy storage system for use during peak hours. It can not only serve as an emergency power source, but also save electricity expenses for the family.

It is necessary to measure and monitor electrical parameters and measure energy in AC side of tower base station such as state grid, diesel, air conditioner, lighting, power supply and so on. In DC side, to monitor electrical parameters and measure energy such as base station communication device, battery and other devices working under -48V power supply. The data can be real-time uploaded by RS485.
