EC2460 serves as both an energy storage device in small optical storage systems and an outdoor power supply product. It is equipped with a built—in 1500Wh lithium—ion battery pack and a fully enclosed metal shell design, which makes it aestheti—cally pleasing. At the same time, it also meets the characteristics of dust prevention, water resistance, and fire resistance, which are essential product features. Micro inverters can also convert direct current stored in mobile power sources into alter—nating current for household loads, in order to reduce household electricity costs.Throughout the entire process, the user can monitor and manage electricity usage at multiple levels based on their actual electricity consumption
