The Mini Grid, Engineered as One System
A mini grid is not a pile of components. It is a technology ecosystem. Sigma designs generation, storage, control, distribution, metering, and payments to work as a single connected machine that powers communities profitably.
How the system works
The Ecosystem
Every Component Talks to the Platform
Inverters report generation, batteries report state of charge, meters report consumption and vending, and the site controller balances them all. Operators see one live picture; customers just see reliable power.

Capabilities
Complete Mini Grid Component Stack
Ten subsystems, one integrated deployment, designed, installed, and operated with a single data backbone.
Solar Generation
High-yield PV arrays sized from demand studies, engineered for hot, dusty conditions.
Battery Storage
LFP battery banks with advanced BMS for safe overnight supply and peak smoothing.
Inverters & Controllers
Grid-forming inverters and site controllers that keep frequency and voltage rock-steady.
Distribution Infrastructure
LV networks, poles, and service drops built to utility standards for safe last-metre delivery.
Smart Metering & Connections
Every customer connection metered, prepaid, and remotely manageable from day one.
Payments & Energy Management
PAYG vending, tariff management, and demand-side control that keep sites bankable.
Build a Mini Grid That Runs Itself
From feasibility and demand studies through commissioning and operations, Sigma delivers mini grids as complete, connected ecosystems.
