Characteristics of backend system:

Account opening management: Enter new users into the management system for easy information management and querying in the future.
● Electricity purchase/sale: You can input the electricity purchase reading, and the system will automatically calculate the amount based on the preset electricity price. You can also input the amount to automatically calculate the electricity consumption.
Electricity price management: The price of electricity can be adjusted, and only administrators have permission.
Report statistics: It can perform statistics, analysis, export, printing, etc. on the electricity consumption data of each user.
Meter reset: Used to clear the data of the energy and quantity inside the meter, only the administrator account has permission.
Power Authority: Allow users to use the maximum load power, and if it exceeds this value, the meter will automatically trip and cut off power. (For example, if the total household electricity load is set at 3000W, power will be cut off if exceeded)
● Account cancellation operation: Used to cancel the profile and other information of electricity meter users, with only administrator account permissions.
Power outage/disconnection: Through remote system operations such as opening/closing, it facilitates the maintenance and repair of one's own circuit, and can also be used to restrict user electricity usage and other operations.
IC power purchase card: The power sales information on the power purchase card is consistent with the system, and the two can be used interchangeably.
● Historical query: Conduct a query and analysis of the user's historical electricity usage.
SMS reminder: also known as power alarm, when the remaining power of the meter is less than the set value, the system reminds users to purchase electricity in a timely manner through SMS on their mobile phones. Divided into first level alarm prompts and second level alarm prompts.
Malignant load permission: Allow users to use the maximum malignant load value, and if it exceeds the maximum value, the meter will automatically shut down. (For example, setting 2000W limits the use of soldering irons that exceed this value, or this limit can be waived.). ）
