Combination Load Center for Parallel Power Source Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical service systems struggle to seamlessly integrate secondary power sources, such as home wind turbines and solar energy systems, into the power supply environment, and lack efficient methods for interfacing these sources with utility grids, especially during utility power failures or excessive power variations.
Innovation Solution
A parallel electrical service system that includes a utility power source, an inverter, a load center with main service disconnect breakers, a utility meter, and parallel source disconnect breakers, allowing for the integration of secondary power sources like solar modules, wind generators, or fuel cells, and enabling power flow between these sources and the utility grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If secondary power sources are installed after home construction, then adaptability to existing structures is improved, but integration complexity into the power supply environment increases
Solution Approach 1:
The patent combines the meter socket and load center into a single integrated enclosure, creating a combination load center that consolidates multiple electrical components. This merging approach simplifies post-construction installations by providing a unified interface for connecting secondary power sources to existing electrical systems, reducing the number of separate components that need to be integrated.
Solution Approach 2:
The combination load center serves multiple functions: it houses the utility meter, provides main service disconnect breakers, accommodates parallel source disconnect breakers for secondary power sources, and distributes power to various circuits. This multi-functional design allows a single device to handle both traditional utility power connections and integrated secondary power source connections, reducing overall system complexity.
2Reliability
If secondary power sources are integrated into the power supply environment, then power supply reliability is improved, but system complexity increases
Solution Approach 1:
The patent divides the electrical system into distinct functional segments within the combination load center: the utility power section with meter inputs/outputs, the load center section with main service disconnect breakers, and the parallel power source section with parallel source disconnect breakers. This segmentation allows each power source to be independently controlled and connected, improving reliability through redundancy while managing complexity through organized separation of functions.
Solution Approach 2:
The combination load center acts as an intermediary device between utility power sources and secondary power sources. It provides a centralized interface that manages connections between different power sources and the electrical load, simplifying the integration process while enabling reliable power supply from multiple sources through structured electrical pathways.
3Ease of manufacture
If meter socket and load center are separated, then ease of installation is improved, but space utilization increases
Solution Approach 1:
The patent merges the meter socket and load center into a single combination enclosure, consolidating components that traditionally occupied separate locations. This integration reduces the total space required in the electrical service area while maintaining installation simplicity through a pre-assembled unit that functions as a single installable component.
