Best fit
NB-IoT is useful when meters are spread across locations where WiFi or wired Ethernet is not reliable and data volume is modest.

NB-IoT energy monitoring fits substations, utility rooms, retail branches, farms, charging areas and distributed solar sites where energy data is needed daily or hourly.
Metering architecture
A smart energy meter measures voltage, current, power, power factor and kWh. Data is sent through an NB-IoT module or through an RS485 collector with cellular uplink.
Commercial value
Remote metering reduces manual reading, supports energy allocation and detects abnormal consumption. Contractual tenant billing requires a meter, accuracy class, installation and approval path accepted by the local authority; it is not implied by adding NB-IoT connectivity.
Equipment in the system
System design, software integration, PLC/SCADA programming and site installation responsibilities are agreed in the written project scope.
Data destination
Customer platform or an agreed third-party service

FAQ
When is NB-IoT better than 4G LTE?
NB-IoT is suitable for small, periodic energy data where coverage is available and power consumption must stay low. 4G LTE is better for higher data volume or richer gateway functions.
Can the system connect existing RS485 meters?
Yes. Existing RS485 / Modbus meters can often be collected by a cellular gateway when register maps and wiring conditions are available.
How is NB-IoT meter data delivered?
SunGene prepares the selected meter or gateway hardware and the agreed data path for a customer-owned dashboard, SCADA or platform. The quotation confirms the endpoint, payload, ownership and recurring operation.
