Innovation Solution
A photovoltaic power generation system incorporating a smart meter for real-time power measurement, bidirectional communication with the grid and load, a PV inverter for DC to AC energy conversion, and a control device with wireless communication to remotely manage and monitor the inverter operations, allowing users to control and acquire information without direct access to the inverter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the photovoltaic inverter is installed in outdoor or hard-to-reach locations for safety and appearance reasons, then safety and appearance are improved, but accessibility for control and monitoring deteriorates
Solution Approach 1:
The patent introduces a communication module as an intermediary between the inverter and the user's terminal device. This module transmits operational data and receives control commands through wireless communication, allowing users to monitor and control the inverter remotely without needing physical access to the installation location.
2Reliability
If the photovoltaic inverter is installed in outdoor or hard-to-reach locations, then safety is improved, but the risk of electric shock to users deteriorates
Solution Approach 1:
The communication module serves as a safe intermediary that handles all user interactions with the inverter remotely. Users can control the inverter's operation mode and monitor its status through their terminal devices without approaching the installation location, completely eliminating the risk of electric shock while maintaining system controllability.
3Productivity
If real-time power information measurement and communication are implemented, then energy efficiency and user control are improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the inverter system: power conversion (DC to AC), real-time power measurement, wireless communication module for data transmission, and remote control capability. By combining these functions in a unified system, the patent achieves improved energy efficiency and user control while managing complexity through functional integration rather than separate components.
