STS Integrated Keypad Three Phase Smart Digital Prepaid Electricity Meter
Product introduction
Stron STE38-A is STS integrated keypad three phase smart digital prepaid electricity meter with multiple function such as prepaid function,memory function: display function,detection function,accurate billing.It is portable design and can be put communication modules inside.
The importance of smart energy meter
Smart meters can provide a powerful help to realize the automation of smart grid.It can monitor the running state of the power grid in real time, and can track and detect the whole process of users' power consumption, so as to optimize the power consumption scheme and improve the efficiency of the use of electricity.
Through the supervision of smart electricity meters, it can standardize the way of electricity consumption of users and achieve the goal of electricity saving.In the next stage, the development direction of smart meter technology is: firstly, the trace-ability of metering original data and the relative separation of non-metering functions;The second is to dual-core, multi-core, data sharing and security development, the third is the communication and network technology to innovate and upgrade.

Recharge solutions introduction
1. By Stronpay vending Software
When it it no credits,the meter will switch off,users can recharge by going to local sales point or use handheld mobile vending unit.Once they get the 20 digits TOKEN,input it by integrated keypad and will recharge successfully.
2.By the third party platform or local mobile payment with API
In some areas,utility is too far and it takes users too much time to go there.Now users can directly use the third party APP to buy electricity,normally they will receive the TOKEN by SMS and enter it to the meter,then recharge completes.
3.By the AMI System
AMI System is a remote reading system based on GPRS and RF-LoRa connected with energy meters where online recharge is available.
