The present invention addresses the problem of providing a power conversion system and a power storage system which make it difficult for a foreign object such as dust to enter an internal space of acasing from a suction port. A power conversion system (2) is provided with: a casing (external casing (3)); and a power conversion device (7). The power conversion device (7) is disposed in an internal space (300) of the casing. A suction port (31) and an exhaust port (32) are formed on the outer peripheral surface (301) of the casing. The exhaust port (32) is connected to the suction port (31) through the internal space (300) of the casing, and is located below the suction port (31). 本发明要解决的问题是提供使诸如灰尘等的异物难以从进气口进入壳体的内部空间的电力转换系统和电力存储系统。电力转换系统(2)设置有：壳体(外部壳体(3))；和电力转换器(7)。电力转换器(7)布置在壳体的内部空间(300)中。壳体的外周面(301)上形成有进气口(31)和出气口(32)。出气口(32)通过壳体的内部空间(300)与进气口(31)连通并且位于进气口(31)的下方。
