Prepaid and postpaid smart meters with STS vending, tamper detection, and remote reads, turning every connection into revenue-grade data.
02
Renewable Energy Metering
Generation, storage, and consumption metering for solar plants, mini grids, and distributed energy resources, measured end to end.
03
Mini Grid Technology
Complete mini grid ecosystems: PV generation, LFP storage, controllers, distribution, smart metering, and pay-as-you-go billing.
04
E-Bikes & Smart Mobility
Connected electric bikes with swappable batteries, GPS telemetry, and fleet management, mobility as part of the energy system.
05
Swap Cabinets & Charging Stations
Solar-powered battery swap cabinets with slot-level telemetry, app or RFID unlock, and pay-per-swap billing.
06
EV Charging Infrastructure
Smart charging stations with OCPP connectivity, renewable supply, session billing, and utilisation analytics.
07

Off-grid public lighting with LFP storage, adaptive motion dimming, and pole-by-pole remote monitoring.
08
Backup Diesel Generators
Standby gensets from 10kVA to 1000kVA with automatic transfer switches, solar hybrid control, and fuel telemetry.
09
Energy Intelligence Platform
The software layer that connects meters, grids, chargers, and fleets: monitoring, analytics, payments, and remote control in one place.
Smart Energy Meters
Every Connection Becomes Revenue-Grade Data
Sigma smart meters combine STS prepaid vending, remote reads, and tamper detection with always-on connectivity, so utilities, mini grid operators, and estates see consumption, revenue, and grid health in real time.
- Prepaid and postpaid smart electricity meters
- STS token vending with mobile and agent top-up
- Remote disconnect, reconnect, and firmware updates
- Consumption analytics and revenue monitoring per feeder

Mini Grid Technology
A Complete Grid, Engineered as One System
From solar generation and LFP storage to distribution, smart metering, and pay-as-you-go payments, Sigma mini grids are deployed as a single connected ecosystem where every component talks to the platform.
- Solar PV generation with battery energy storage
- Grid-forming inverters and site controllers
- Smart metering at every customer connection
- Prepaid vending, payments, and remote monitoring
E-Bikes & Smart Mobility
Electric Mobility, Built Into the Energy System
Sigma e-bikes pair efficient hub motors and swappable LFP batteries with GPS and IoT telemetry, giving riders range confidence and giving fleet operators live tracking, battery health, and charging logistics.
- Smart e-bikes with swappable battery packs
- Battery swap and charging station infrastructure
- GPS tracking, geofencing, and remote immobilisation
- Fleet management with battery health analytics

Swap Cabinets & Charging Stations
Refuelling an Electric Fleet in Under a Minute
Sigma swap cabinets hold charged packs where riders already are. A depleted battery goes in, a full one comes out, and every bay reports its charge state, temperature, and revenue back to the platform.
- Modular cabinets in 4, 8, and 12 bay configurations
- Solar and grid supply with per-slot current control
- App or RFID unlock with pay-per-swap billing
- Slot-level telemetry on charge, health, and cycles

EV Charging Infrastructure
Charging Networks Powered by Renewables
We design and deploy EV charging stations that run on solar and storage where the grid is weak, with OCPP connectivity, smart load management, session billing, and utilisation analytics built in.
- AC and DC charging stations with OCPP
- Solar-plus-storage powered charging hubs
- Smart charging and dynamic load management
- Pay-per-charge billing and fleet charging accounts

Solar Street Lighting
Public Lighting That Runs Without the Grid
Every Sigma street light is a small solar plant on a pole: PV, MPPT charging, LFP storage, and adaptive LED optics sized together, so roads, estates, and communities stay lit with no cabling and no metered consumption.
- All-in-one and split PV lighting systems
- LFP storage sized for multiple cloudy nights
- Motion sensing with dusk-to-dawn dimming profiles
- Pole-by-pole monitoring of charge, burn hours, and faults

Backup Diesel Generators
Standby Power, Sized and Instrumented
We supply, install, and monitor diesel generating sets from 10kVA to 1000kVA with automatic transfer switches and acoustic canopies. Paired with solar and storage, the same set runs far fewer hours on far less fuel.
- Gensets specified against your measured load profile
- Automatic transfer switches and changeover panels
- Solar hybrid control that cuts diesel running hours
- Fuel level, engine hours, and alarms on the platform
