The present invention relates to the field of electric energy storage, and specifically to an energy storage system and device based on the integration of source, grid, load and storage, comprising a battery system (BS), a power conversion system (PCS), a battery management system (BMS) and a monitoring system. The system solves the problem that a basic module within an existing single-battery cabinet generates heat during use, and in hot weather, the heat is less likely to dissipate into the external environment.
