Description

Technical Field

[0001] The invention relates to the technical field of micro-inverters, in particular to an auxiliary positioning device for assembling a micro-inverter. Background Art

[0002] Micro inverters generally refer to inverters with a power of less than or equal to 1000 watts and component-level MPPT in photovoltaic power generation systems. The full name is micro photovoltaic grid-connected inverter. "Micro" is relative to traditional centralized inverters. The traditional photovoltaic inverter method is to connect all the DC power generated by all photovoltaic cells under sunlight in series and parallel, and then use an inverter to invert the DC power into AC power and connect it to the grid; micro inverters invert each component. Its advantage is that each component can be independently MPPT controlled, which can greatly improve the overall efficiency. At the same time, it can also avoid the DC high voltage, poor weak light effect, and barrel effect of centralized inverters.

[0003] Most of the existing micro inverters are installed by a micro inverter housing, a circuit board and a cover plate, wherein a connector is installed on the circuit board, and a snap groove is provided on the connector, and the snap groove cooperates with the micro inverter housing. The installation of the circuit board and the micro inverter housing is completed by tightening the screws on the circuit board. The circuit board is provided with multiple screws, and the staff is required to align the circuit board with the micro inverter housing and tighten the screws. The operation is frequent and the work efficiency is low. Then, during the placement of the circuit board, dust will accumulate on its surface. If it is not cleaned during the installation process, the resistance value of the circuit board will increase in subsequent use, and the temperature rise will be accelerated, thereby reducing the use time.

The movement of the grid plate will drive the bearing A to move, and the bearing A drives the rotating ring to move. Because the thread on the inner wall of the rotating ring cooperates with the threaded rod and is connected to the inner ring of the bearing A, the rotating ring will start to rotate, and the rotating ring drives the fan blades to rotate, thereby generating wind force, and the wind force is downward to clean the dust on the circuit board.
