Solution Overview
Problem
Integrating a stand-alone energy control system with various residential electrical systems is challenging due to differences in power distribution, service panel types, load breaker sizes, and the presence of alternative energy sources like photovoltaic power generation and energy storage systems.
Innovation Solution
A method for integrating an energy control system with an electrical system involves determining site conditions and backup configurations to locate and couple key components such as main circuit breakers, PV systems, and site current transformers, allowing the energy control system to be positioned downstream of the utility meter and upstream of electrical loads, thereby improving load management and photovoltaic power supply efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a stand-alone energy control system is integrated with various residential electrical systems, then load management and photovoltaic power supply efficiency are improved, but integration complexity increases due to differences in power distribution, service panel types, load breaker sizes, and alternative energy sources
Solution Approach 1:
The energy control system is divided into modular functional components including a control panel, transfer switch, photovoltaic disconnect, and interconnection devices. Each module handles specific tasks (load management, power transfer, PV disconnection) allowing the system to be adapted to different residential electrical configurations without requiring complete system redesign, thus improving load management while controlling integration complexity
Solution Approach 2:
The energy control system is designed with universal interconnection capabilities that can interface with various service panel types (main panel, subpanel), different power distribution configurations (single-phase, three-phase), and multiple alternative energy sources (photovoltaic systems, energy storage systems). This multi-functionality allows a single system design to handle diverse residential electrical systems, improving productivity without proportionally increasing integration complexity
2Ease of operation
If the energy control system is positioned downstream of the utility meter and upstream of electrical loads, then load management capability is improved, but determination of optimal component locations becomes more challenging due to diverse system configurations
Solution Approach 1:
The patent provides predetermined installation guidelines and configuration protocols that specify optimal component locations based on common residential electrical system types. By establishing these location determinations in advance (before installation), the system reduces on-site decision-making complexity while ensuring proper load management capability is achieved
Solution Approach 2:
The energy control system components are designed with location-specific functional characteristics. For example, the transfer switch is positioned to control specific load groups, the PV disconnect is located near the photovoltaic interconnection point, and the control panel is sited for optimal access and wiring. This local optimization of component placement improves load management while making location determination more systematic rather than purely site-specific
3Adaptability or versatility
If backup configuration types are determined based on site conditions, then system adaptability to different residential configurations is improved, but the integration process becomes more complex requiring determination of multiple parameters
Solution Approach 1:
The energy control system incorporates configurable settings that can be dynamically adjusted based on the specific residential electrical system configuration. The system can adapt its operational mode (whole home backup, critical loads only, load prioritization schemes) according to site conditions such as service panel type, load breaker sizes, and alternative energy source capacity. This dynamic configurability improves adaptability while keeping the integration process manageable through software-guided setup
Solution Approach 2:
The system allows modification of key operational parameters including backup configuration type (whole home vs. critical loads), load management priorities, photovoltaic interconnection settings, and energy storage integration parameters. By enabling these parameter changes based on site conditions, the system achieves high adaptability to diverse residential configurations without requiring completely different hardware designs for each scenario
