Top-mounted heat dissipation photovoltaic inverter device

A photovoltaic inverter device comprising:

• an inverter comprising:
• an inverter circuit comprising a power circuit board and a power transistor, wherein the power circuit board is configured to fasten the power transistor;
• a box configured to accommodate the power circuit board;
• and
• a top-mounted heat dissipator comprising:
• a top-installed heat dissipation assembly comprising a condenser and a fan assembly arranged adjacently in a second direction;
• and
• a back-mounted heat dissipation assembly comprising an evaporator and an air-cooled heat sink,
• wherein the condenser and the box are arranged in a laminated manner in a first direction,
• wherein the box, the evaporator, and the air-cooled heat sink are arranged sequentially and adjacently in the second direction,
• wherein an orthographic projection of the top-installed heat dissipation assembly does not overlap with an orthographic projection of the back-mounted heat dissipation assembly in a third direction, and
• wherein the first direction, the second direction, and the third direction are orthogonal to each other.
