[0002] Photovoltaic power station cabinets usually refer to electrical control equipment used in solar power generation systems, also known as photovoltaic distribution cabinets or photovoltaic reverse control energy storage cabinets. Their main functions include safety sub-boxing, protection, switch control and power metering, etc., to ensure the safe and stable operation of photovoltaic power stations; photovoltaic power station cabinets are generally installed outdoors for use, and waterproof components are generally directly installed on the top of the photovoltaic power station cabinets, which can play a waterproof protection role.
[0003] The top of the photovoltaic power station cabinets on the market is generally platform-shaped. The platform-shaped structure is prone to snow accumulation in rainy and snowy weather.

Although the triangular shape is conducive to the sliding of snow, it will still accumulate snow in icy conditions. It cannot be heated to promote the melting of snow and then slide down, which brings inconvenience to users. In view of this, we propose a snow-proof photovoltaic power station cabinet.
