Solar PV Plants for MiniGrid offGrid Rural Single Phase Din Rail
Mounted Kwh Meter With Customer Interface Unit
With extremely rapid growth of solar PV plants in Africa and South
Asia, more and more remote area get electricity power. Those solar
PV plants be called mini-grid, micro grid or off grid, effectively
provide necessary electricity for daily usage, lighting, phone
charge, radio and TV. In order to ensure that the provider of solar
PV generation, it is necessary to meansure the power consumption so
that the provide have enough profit to operate the plants, develop
more plants, furthermore promote the prosperity of the whole
Mini-Grid industry.
The CA168-S is designed for accurate measurement and prepayment
function. The project will have faster return of fund because of
the prepayment function. As the DIN RAIL type, MCU(Main Control
Unit) and CIU (Customer Interface Unit) design, The MCU (Main
Control Unit) can be installed in a locked box or high electric
pole, and only give the CIU to the users. The user can recharge for
his meter, and query balance, recharge record and amount, etc by
CIU. Also it is the most effective action for anti tamper.
Major Features

cover open, etc.
- Reverse energy measurement SRE
- Information toggled by codes
- Tamper trip protection : neutral missing
Other Benefits
a) Compact and slim-line design
b) PLC/ RF communication for MCU & UIU and same with back end AMI
server (On request)
c) Time of Use (TOU) , multi-rate, tariff control, holiday setting
d) 15 year designed life
e) Enhanced revenue protection through flexible payment control
