Off-grid Solar Power GPRS Smart Prepaid Solar Metering Box Solution-Stron Smart

 

Model STB560-A Metering‐box (hereafter referred as M‐box) is a multi‐function metering solution composed of Box, Measurement & Control Unit (MCU), GPRS module, LORA-RF module and Customer Interface Unit (CIU).  Each M‐box can access the far‐end servers via GPRS, so that the administrators can operate M‐boxes and read all the meters’ energy consumption information remotely.

The M-box is composed of PC (polycarbonate) cover and ABS base, with performance of reliable insulation, high strength, good flaming resistance, anti‐corrosion, anti‐aging and lifetime of over 10 years. It could be widely used in housing construction or civil power grids transformation, with features of multiple combinations of different metering units, easy installation, hidden cable connection and safe operation.

By operating M‐boxes and read all the meters’ energy consumption information remotely, it can help utility companies to largely improve the management efficiency of their power grids, and reduce the management cost.

For users, CIU installed in their homes could achieve energy consumption data from M‐boxes via LORA-RF communication, and display to users, so that it is not only convenient for them to read data, but also avoid disruption of energy measurement. Thus, this is a complete metering box solution which combines measurement, use and management of energy.
