Description

Technical Field

[0001] The utility model relates to the technical field of micro inverters, in particular to the technical field of installation and removal safety of micro inverters, and specifically refers to a grounding gear used for improving the installation and removal safety of micro inverters. 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 inverters. "Micro" is relative to traditional centralized inverters. The traditional photovoltaic inverter method is to connect all the DC power generated by 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, and at the same time avoid the DC high voltage, poor weak light effect, and barrel effect of centralized inverters.

[0003] See also Figure 1 As shown, the micro inverter 1 generally includes a housing 2, a PCBA (not shown in the figure) and a hanging piece 3.

The left and right ends of the hanging piece 3 are vertically provided with hanging holes 4. The photovoltaic power support 5 is also rectangular in shape, also horizontally arranged and arranged along the left-right direction. The photovoltaic power support 5 is vertically provided with mounting holes 6. During installation, the hanging piece 3 is abutted against the photovoltaic power support 5, and the micro inverter 1 is hung on the photovoltaic power support 5 by installing bolts (not shown in the figure) to vertically penetrate the hanging holes 4 and the mounting holes 6 and screw on the nuts.

[0033] See also Figure 2 to Figure 4 As shown, in a specific embodiment of the present invention, the grounding gear 7 for improving the installation and removal safety of the micro inverter of the present invention is a conductive element and includes a central plate 8 and a tooth 9, wherein:

[0034] The center plate 8 is horizontally arranged, and a fixing hole 10 is vertically arranged on the center plate 8. The tooth member 9 is located outside the outer peripheral side surface of the center plate 8 and is connected to the outer peripheral side surface of the center plate 8. The tooth member 9 protrudes downward from the lower surface of the center plate 8. There are multiple tooth members 9, and the multiple tooth members 9 are horizontally arranged around the center plate 8 and spaced apart from each other.

[0036] The number of the teeth 9 can be determined as required. The above-mentioned "multiple" means more than 2. Figure 2-3As shown, in a specific embodiment of the present invention, the number of the tooth members 9 is 24.
