1、 Selection of current specifications
Basic current and rated current: The smart energy meter panel usually indicates two current values, such as 5 (60) A, where 5A is the basic current and 60A is the rated maximum current. When selecting, it should be ensured that the current specifications of the selected electricity energy meter are neither lower than the basic needs of household electricity nor exceed the rated maximum current of the energy meter to prevent overload damage.
Calculation of household appliance power: Calculate the total current demand based on the power of commonly used electrical appliances in rural households, such as televisions, refrigerators, washing machines, air conditioners, etc. Generally speaking, the total current value can be obtained by adding the power of each electrical device and dividing it by the voltage (usually 220V). Considering the potential increase in electrical equipment in the future, it is recommended to reserve a certain amount of current margin.
2、 Selection of functional requirements
Remote energy meter reading function: This is the basic requirement for selecting a remote energy meter reading energy meter, which can read energy meter data in real-time and reduce the trouble and errors of manual energy meter reading.
Data storage and event recording: The electricity energy meter should have data storage function, which can record historical electricity consumption data, facilitating energy consumption analysis and energy-saving optimization for users and management personnel. At the same time, the event recording function can record changes in the working status of the electricity energy meter, such as power outages, power restoration, etc., which is helpful for troubleshooting and safety management.
Anti electricity theft function: In order to prevent electricity theft, the electricity energy meter should have anti electricity theft function, which can monitor and record abnormal electricity consumption.
Energy management function: Some advanced electricity energy meters also have energy management functions, which can provide personalized energy-saving suggestions and optimization solutions for users, helping them use electricity resources reasonably.
3、 Selection of Quality Reliability
Brand selection: Well known and reliable quality electric energy meters should be chosen. These brands typically have well-established production processes and quality control systems to ensure the quality and performance of electricity energy meters.
After sales service: Consider whether the after-sales service of the electricity energy meter is complete, including installation guidance, fault repair, etc. Choosing a brand with good after-sales service can ensure that any problems encountered during use can be resolved in a timely manner.
4、 Selection of Remote energy meter Reading Scheme
Wired energy meter reading solution: such as RS-485 solution, suitable for small-scale centralized installation of electricity energy meters. This solution has low hardware cost and stable performance, but requires the laying of communication lines, making construction difficult.
Wireless energy meter reading solution: such as NB IoT/4G wireless energy meter reading solution, suitable for situations where electricity energy meters are installed in a dispersed or distant manner. This scheme does not require the laying of communication lines and is easy to construct, but the hardware cost is relatively high.
In summary, when selecting suitable remote energy meter reading energy meters for rural houses, comprehensive consideration should be given to factors such as household electricity demand, functional requirements, and quality reliability. At the same time, it is necessary to choose a suitable remote energy meter reading solution based on the actual situation.
