Technical Field

[0001] The utility model relates to the technical field of photovoltaic inverters, in particular to a photovoltaic inverter capable of being externally connected with a heat dissipation module. Background Art

[0002] Photovoltaic inverters are devices that can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency. They are one of the balancers of the photovoltaic array system and have strong regulation capabilities. By interacting with the power grid and shaving peaks and filling valleys, they can maximize profits.

[0003] In order to ensure a constant state during use, a traditional photovoltaic inverter is provided with a mounting frame on one side of the inverter surface, and is cooled by an external heat dissipation device. When the photovoltaic inverter is in use, several connecting wire harnesses connected to other devices are installed on its connector to ensure the corresponding stable coordination. However, in actual use, it is found that because there are many connecting wire harnesses installed, cross-entanglement and bending may occur, resulting in mutual friction and damage of the wire harnesses, causing the internal copper wire to be exposed, affecting the normal use of the equipment. It is also not conducive to personnel to conduct inspections and repairs, affecting the normal use of the photovoltaic inverter. Utility Model Content
