Description

Technical Field

[0001] The utility model relates to the technical field of micro inverters, in particular to the technical field of micro inverter installation, and specifically refers to a reinforcement bracket used for stably installing a micro inverter on a photovoltaic power supply bracket. 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.
