Residential ESS (Energy Storage System) is an energy storage and management system used in residential environments. It can store electricity from the grid or renewable energy generation equipment (such as solar panels) and release it for household use when needed.Residential ESS has significant advantages in energy storage and load balancing, energy self-sufficiency, addressing grid failures, and optimizing energy management. It provides reliable energy supply for households, reduces energy costs, and has a positive impact on the environment.
