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.
