Energy storage all-in-one machine and energy storage system

The utility model discloses an energy storage all-in-one machine and an energy storage system, and belongs to the technical field of battery energy storage. The energy storage all-in-one machine comprises a battery, a switch box and at least two connectors. The switch box is electrically connected with the battery; and the connector is used for realizing the capacity expansion of the energy storage all-in-one machine. The at least two connectors are arranged in the energy storage all-in-one machine, so that connecting wires between the energy storage all-in-one machine and the outside can be reduced, capacity expansion is facilitated, installation of the energy storage all-in-one machine is simplified, even if the energy storage all-in-one machine needs to be replaced or debugged, a single energy storage all-in-one machine can be rapidly disassembled by directly pulling out the cables connected with the corresponding connectors, operation is simple, and cost is low. Time and labor are saved. 本申请公开了一种储能一体机及储能系
