A power pole inverter is provided. The power pole inverter includes a housing assembly, a capacitor assembly, a number of arm assemblies, a number of heat sinks, and a support assembly. The housing assembly includes a number of sidewalls. The housing assembly sidewalls defining an enclosed space. The capacitor assembly is coupled to the housing assembly. Each arm assembly includes a plurality of electrical components and a number of electrical buses. Each the electrical bus includes a body with terminals, each the terminal structured to be coupled to, and in electrical communication with, the capacitor assembly, each arm assembly including a neutral terminal. Each arm assembly is coupled to, and in electrical communication with, the capacitor assembly. The support assembly includes a non-conductive frame assembly. The support assembly is structured to support each the heat sink in isolation.
