Smart Electricity Meters

A smart prepaid electricity meter measures energy use and runs on credit paid in advance, much like a prepaid phone plan. Users recharge remotely through an app or web portal, and the meter can disconnect supply through its built-in relay when credit runs out. Raivens builds single- and three-phase prepaid meters with RF, LoRa or 4G connectivity for apartments, hostels, malls and EV charging sites.

With remote recharge, the user adds credit in the mobile app or web portal, and the credit reaches the meter over its RF, LoRa or 4G link. If the relay had disconnected supply at zero credit, power can be restored once the recharge arrives. Nobody needs to visit the meter or a site office. Raivens sets up the app and portal for each site.

Multi-channel sub-metering uses one meter to measure several separate circuits. Raivens multi-channel meters handle up to 10 channels, so one device in an electrical panel can meter up to 10 shops, offices or charging bays. The result is fewer meters to install, fewer communication links to manage and one place to read every tenant's consumption, which suits malls and commercial buildings.

The right wireless link for smart meters depends on site layout. RF and LoRa suit buildings and campuses with many meters close together, since one network covers them all, and LoRa adds range for spread-out sites. 4G suits standalone meters, such as a single shop or a remote charging bay, because each meter connects directly over the cellular network. Raivens recommends the link after a site survey.

When prepaid credit reaches zero, the meter can disconnect supply through its built-in relay, depending on how the site is configured, and supply can be restored after a recharge. Site owners decide how disconnection is handled for their property. Users can see their balance in the app and recharge in time. Raivens configures these rules with the owner during commissioning.

Yes. Raivens smart meters raise tamper alerts and report them to the portal, so site managers can investigate quickly instead of discovering a loss at the next manual reading. Combined with remote readings and relay control, this helps protect revenue in rented rooms, hostels and shared buildings. Tamper detection details for each model are available on request.

Yes. A smart meter on each charging bay records the energy that bay uses, so a building can bill EV charging per bay, resident or tenant on prepaid or postpaid terms. Three-phase meters suit 11 and 22 kW AC chargers. Raivens builds both the meters and the chargers, so one team can plan metering and charging together.

Metering rules for smart electricity meters differ between countries and utilities, so requirements are reviewed for each project. Compliance documentation per model is available on request, along with details on accuracy, phase configuration and communication options. Ask Raivens early in the project, so your consultant can confirm fit with local grid and metering standards before installation begins.
