Microinverter Bluetooth Locking for Secure Remote Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microinverters, due to their outdoor application and waterproofing requirements, lack flexible control over Bluetooth signal on/off states, leading to security risks and poor user experience as external switches are not feasible.
Innovation Solution
A method and apparatus for controlling Bluetooth locking of microinverters, enabling Bluetooth signal control through network connections with user terminals and servers, using flags to ensure secure switching between locked and unlocked states only when network connections are successful, and allowing temporary signal activation via disconnection from local networks or power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth signal is always on for local control, then user convenience is improved, but security risk increases due to unauthorized access
Solution Approach 1:
The Bluetooth signal state is changed from static (always on) to dynamic (switchable between on and off states). The control unit enables remote switching of the Bluetooth signal based on control instructions received from the terminal device, allowing the system to adapt its Bluetooth availability dynamically according to user needs and security requirements.
2Adaptability or versatility
If external hardware switches are added for Bluetooth control, then control flexibility is improved, but device waterproofing and structural integrity are compromised
Solution Approach 1:
The control unit acts as an intermediary between the terminal device and the Bluetooth module. Instead of requiring physical external switches, the control unit receives control instructions from the terminal device via network communication and automatically switches the Bluetooth signal state accordingly, eliminating the need for external hardware switches while maintaining control flexibility.
Solution Approach 2:
The mechanical external hardware switch system is replaced with an electronic control system. The control unit processes electronic control instructions from the terminal device and electronically switches the Bluetooth signal state, substituting mechanical operation with electronic control to maintain waterproofing while achieving control flexibility.
3Object-affected harmful factors
If Bluetooth locking control is enabled, then security is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The control unit performs multiple functions: it manages network communication with the terminal device, processes control instructions, switches Bluetooth signal states, and monitors system operations. By making the control unit multi-functional, the patent avoids adding separate dedicated hardware for Bluetooth locking control, thereby minimizing the increase in device complexity while achieving enhanced security.

AI summary
A microinverter Bluetooth locking method and device, and a medium therefor, relating to the technical field of distributed power generation systems, for use in achieving the locking control of a Bluetooth signal from a microinverter. Regarding the existing problem that flexible turning-on/turning-off of Bluetooth is not supported, the microinverter Bluetooth locking method is provided. Firstly, networking information uploaded by a user is received by means of a Bluetooth signal, such that a microinverter is connected to a local area network, then connected to the Internet by means of a router, and thus connected to a remote server, to achieve remote network control of the microinverter. Subsequently, the user can control the locking of the Bluetooth signal from the microinverter without using an external switch, thereby effectively solving the problem that an external switch is not suitable for being provided due to a special application environment of a microinverter. Additionally, a Bluetooth signal can be activated in a locked state by disconnecting the microinverter from the network, thereby achieving more flexible use and maintenance of the microinverter.
