[0002] Photovoltaic inverters are inverters that can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverters are one of the important system balances in photovoltaic array systems. They can be used with general AC-powered equipment. Solar inverters have special functions for photovoltaic arrays. Photovoltaic inverters are usually installed close to photovoltaic battery groups. The box should be installed in a well-ventilated place, avoiding direct sunlight and humidity. At the same time, the stability of the installation location and the load-bearing capacity of the structure need to be ensured. It includes two installation methods: ground and wall.

[0003] The solar photovoltaic inverters currently on the market have the following problems when in use:

[0004] 1. When installing traditional solar photovoltaic inverters, you need to find a ventilated place that avoids sunlight and moisture. After choosing a suitable installation location, you either fix it on the wall or bracket, or fix it on the ground. As a result, when adjusting the installation location, the staff needs to carry a variety of mounting brackets and bases, which makes the installation less convenient for the staff and is time-consuming and laborious to operate.

[0005] 2. Most solar photovoltaic inverters require regular inspection and maintenance, and internal components need to be checked during the inspection and maintenance. Therefore, long-term inspection and maintenance require repeated disassembly and maintenance of the box, which is very inconvenient and time-consuming and laborious for the staff to operate.
