Abstract

Disclosed are a card-inserting type photovoltaic micro-inverter, a photovoltaic component capable of being installed with the card-inserting type photovoltaic micro-inverter, an installation tool and a fast installation method, which belong to the technical field of alternating-current components in the solar photovoltaic industry. Two card pins (5) are provided on the sides of a connecting piece (2) of the card-inserting type photovoltaic micro-inverter (1), and two card slots (9) are provided on the sides of a metal frame (8) of a corresponding photovoltaic component. The installation tool comprises a pull rod (13) and a link bar (15), the design thereof conforms to the lever principle, and the installation steps are as follows: a. getting the card-inserting type photovoltaic micro-inverter, enabling the sides of the connecting piece (2) facing towards the sides of the metal frame (8)of the photovoltaic component, respectively aligning the two card pins (5) on the sides of the connecting piece (2) with jacks (10) of the two card slots (9) on the sides of the metal frame (8) of the photovoltaic component, and inserting the card pins (5) in the jacks (10) of the card slots (9), and b. rotating the pull rod (13) by means of the installation tool, enabling the card pins (5) to be tightly clipped in bayonets (11) of the card slots (9). The solution can guarantee stable and reliable connection between the photovoltaic micro-inverter and the component and can also greatly reduce the installation time for the photovoltaic micro-inverter, thereby improving the production efficiency of the alternating-current component and reducing the production cost.

Description

technical field [0001] The invention belongs to the technical field of AC components in the solar photovoltaic industry, and specifically relates to a tool and a quick installation method for installing a card-type photovoltaic micro-inverter on a photovoltaic module. Background technique [0002] In recent years, in solar photovoltaic applications, it has become a development trend to convert the DC power generated by the modules into AC for direct application or grid connection. AC modules with built-in photovoltaic micro-inverters are gradually popular due to their easy installation and use. [0003] There are generally two methods for the combination of photovoltaic micro-inverters and photovoltaic modules: one is to install photovoltaic micro-inverters on the module brackets during the installation of photovoltaic power generation systems, and then connect them to the modules. This method increases the difficulty and cost of photovoltaic system installation, and is grad...
