Abstract: An outdoor energy storage system cabinet and an outdoor energy storage system are provided. The cabinet includes a cabinet body, a water firefighting system, and a gas firefighting system. The water firefighting system includes a water firefighting pipe. The water firefighting pipe is arranged at a top part of an interior of the cabinet body and is provided with a water nozzle. The gas firefighting system includes a gas firefighting pipe. The gas firefighting pipe, like the water firefighting pipe, is arranged on the top part of an interior of the cabinet body. The gas firefighting pipe is configured to contain a firefighting fire extinguishing agent or transport the firefighting fire extinguishing agent. The gas firefighting pipe is provided with an air nozzle for ejecting firefighting gas generated by the firefighting fire extinguishing agent.

Abstract: A photovoltaic energy storage device includes a battery module group, a battery switching device, an EMS controller, a direct current circuit breaker, an inverter and an alternating current circuit breaker. The battery module group, the battery switching device and the EMS controller are integrated in a first insulation compartment of the photovoltaic energy storage device; and the direct current circuit breaker, the inverter and the alternating current circuit breaker are integrated in a second insulation compartment of the photovoltaic energy storage device. A thermal-protective coating is arranged between the first insulation compartment and the second insulation compartment. Therefore, the integration of the photovoltaic energy storage device is divided into two parts, i.e., an integration at a battery side and an integration at an inverter side, and the thermal-protective coating is arranged, to prevent heat convection and heat exchange between the battery side and the inverter side.
