The invention relates to the field of electric power energy storage, in particular to an energy storage system and device based on source network load storage integration, which comprises a battery system BS, a power conversion system PCS, a battery management system BMS and a monitoring system, and solves the problems that in the use process of an existing single battery cabinet, a basic module in the single battery cabinet can generate heat, and in hot weather, the single battery cabinet cannot generate heat; when the container energy storage device works, heat is not easy to dissipate to the external environment, and if the heat cannot be dissipated for a long time, the operation of the basic module and the battery management system is influenced, so that the normal operation state of the whole container energy storage device is interfered; besides, in winter weather with large inside and outside temperature difference, small water drops are often condensed on the inner wall of the single battery cabinet,
