Heatsink configuration and arrangment for inverter and systems, components, and methods thereof

A modular inverter arrangement comprising one or more cages of a cage assembly, including at least a first cage of the cage assembly. Each of the one or more cages can be in the form of a cuboid, and each of the one or more cages can be adapted to accommodate therein respective sets of one or more power modules. The modular inverter arrangement can also be comprised of a heatsink extending transversely through each of the one or more cages, from a first end of the cage assembly to a second end of the cage assembly opposite the first end.
