Standardized Enclosure for Electrical Distribution Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photovoltaic systems lack standardized installation methods for electrical distribution equipment, requiring unique design considerations and individual on-site installation of components, which complicates the layout and increases installation complexity.
Innovation Solution
A standardized enclosure for electrical distribution equipment that houses inverters, AC distribution components, and transformers, with access panels and ventilation grills, allowing for organized and accessible installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical distribution equipment is installed in a non-standardized manner in electrical yards or beneath solar panels, then each system can be customized to specific site requirements, but the layout design becomes uniquely complex for each system and individual on-site installation of each component is required
Solution Approach 1:
The patent combines multiple electrical distribution components (inverters, AC distribution equipment, transformers, communication components, control components) into a single integrated enclosure structure. This merging approach standardizes the layout while maintaining adaptability to different site requirements through configurable internal arrangements and external interfaces.
Solution Approach 2:
The enclosure is designed as a universal platform that can accommodate various photovoltaic system configurations and site requirements. The standardized structure provides multi-functionality by housing different combinations of electrical components while maintaining a consistent external form factor and installation interface.
2Adaptability or versatility
If electrical distribution equipment is installed in a non-standardized manner, then site-specific customization is achieved, but individual on-site installation of each component increases installation time and complexity
Solution Approach 1:
By pre-assembling multiple electrical components within a single standardized enclosure at the manufacturing stage, the patent eliminates the need for individual on-site installation of each component. The integrated unit is installed as one complete assembly, dramatically reducing installation time while maintaining site-specific adaptability through configurable internal layouts.
Solution Approach 2:
The enclosure and its internal electrical components are pre-configured and pre-assembled during manufacturing before delivery to the site. This preliminary action transfers complex assembly work from the installation phase to the manufacturing phase, reducing on-site installation time and complexity.
3Adaptability or versatility
If electrical distribution equipment is installed without a standardized enclosure, then flexibility in component placement is maintained, but accessibility for maintenance and organization of components deteriorates
Solution Approach 1:
The enclosure incorporates multiple access panels that segment the internal space into distinct compartments. Each access panel provides controlled access to specific components or component groups, maintaining organizational structure while allowing flexible internal component placement. The segmentation enables targeted maintenance access without requiring full enclosure disassembly.

AI summary
An enclosure is for electrical distribution equipment including a number of inverters and alternating current distribution components. The enclosure includes: a first side; a second side adjacent to the first side; a third side adjacent to the second side; a fourth side adjacent to the first side and the third side; a top portion; a bottom portion; a number of first access panels installed on one of the first through fourth sides, the number of first access panels being configured to open to provide access to the number of inverters; and a second access panel installed on one of the first through fourth sides, the second access panel being configured to open to provide access to the alternating current distribution components.
