Abstract
A power inverter has an inverter unit with a housing defining a main compartment and a first lateral compartment adjacent the main compartment. The main compartment contains an inverter power module configured to convert direct current (DC) power into alternating current (AC) power output, an inverter driver module configured to provide driving signals to drive the inverter power module, an inverter control module configured to provide control signals to the inverter driver module to control the AC power output, and a capacitor for coupling to the DC power. The capacitor is arranged on or over at least one of the inverter power module, the inverter driver module, or the inverter control module. Additionally, the power inverter has a base on which the housing sits, the base comprising a heat sink configured to draw heat away from one or more of the inverter power module, the inverter driver module, or the inverter control module.
