STE18-d adopts 35 mm DIN rail mounting and rod mounting accessories, which is composed of two parts. Customer interface unit (CIU) and metering control unit (MCU). The CIU is a keyboard based display installed anywhere in a consumer's home with a plug. MCU is the main instrument, which is installed in the information kiosk, instrument box far away from the consumer's home or the shell installed on the pole. MCU communicates with CIU through PLC, RF, Lora or 2 wireless communication. This off-line setting allows utilities and service providers to easily check at any time without having to visit the consumer's house, and reduces the chance of tampering fraud.
The meter can also be integrated with African local mobile money for prepayment, like M-pesa, MTN, Airtel through API(Application Programming Interface), which is the agreement connecting the third party APP and our Stronpay vending software. In this way, users can top up electricity credit by mobile money without leaving the house and could check information by their telephone at hand with internet accessibility.
