Mini Grid PV Solar Generation Local Prepayment Algorithm Prepaid Kwh Meter
with Mobile Money Integration
The CA168-S is split type prepaid Kwh meter with CIU (Cusomter Interface Unit), designed for Mini Grid PV Solar Generation Plant. This model is compliance with STS (Standard Transfer Specification), allows the service provider to make various setting with the meter, such as emergency credit, power limit, low credit warning levle, debt collection policy, etc.
Local Prepayment
Thanks to build in STS prepayment algorithm, and the vending software generate the 20-digit Token based on the STS encryption algorithm, which means the meter can achieve the prepayment functions locally even through there is no any communication between the meter and vending system.
Mobile Money Integration
We can provide a api port of our STS vending software, to integarte into local mobile money platform. When the user pay on the Mobile money APP, our vending software will get a inform to generate the corresponding Token based on the meter ID and recharge amount, and then send the Token to the user's phone by message. The user only need to input the token by the keypad.
Major Features
1) STS standard encryption
2) Up to 1 mile distance of non-wired communication
