Dual-inverter assembly

A dual-inverter assembly comprising:

• an elongated base comprising a first side, a second side, a first elongated sidewall and a second elongated sidewall, wherein the first side and the second side are opposite to each other, and the first elongated sidewall and the second elongated sidewall are opposite to each other and extended along a first direction;
• a first power module arranged along the first direction and disposed on the first side;
• a second power module arranged along the first direction and disposed on the second side;
• an input copper busbar spatially corresponding to the first elongated sidewall, partially extended toward the first side and the second side from the first elongated sidewall, and comprising a first connection portion disposed on the first elongated sidewall and electrically connected to the first power module and the second power module, wherein the input copper busbar is a DC input copper busbar comprising a positive input copper busbar and a negative input copper busbar, which are spatially corresponding to the first elongated sidewall;
• and
• two output copper busbars spatially corresponding to the second elongated sidewall and partially extended toward the first side and the second side from the second elongated sidewall, wherein the two output copper busbars are served as two AC output copper busbars, each of the two output copper busbars comprises a second connection portion disposed adjacent to the second elongated sidewall, one of the second connection portion of the two output copper busbars is electrically connected to an output contact terminal of the first power module along the first side, and another one of the second connection portion of the two output copper busbars is electrically connected to an output contact terminal of the second power module along the second side, wherein the first power module comprises a plurality of first power devices arranged along the first direction and disposed on the first side, and the second power module comprises a plurality of second power devices arranged along the first direction and disposed on the second side.
