Energy Management System & Hybrid Controller — PV · BESS · DG · Grid
Integrated PV · Wind · BESS · DG · Utility — one intelligent platform
A complete Energy Management System that orchestrates solar PV, wind, battery storage, diesel/gas gensets and the utility grid as a single coordinated power plant. Built on DEIF's iE 250 and ASC platforms, our EMS delivers fuel savings, peak shaving, grid-code compliance, renewable maximisation and seamless island/grid-connected operation — engineered, supplied and commissioned by S.A.International.
Overview
The DEIF energy management system acts as a plant-wide hybrid controller, coordinating solar PV, wind, battery energy storage (BESS), diesel/gas gensets and the utility grid from one platform. As a hybrid controller it runs fuel-saver, zero-genset, peak-shaving and grid-forming modes automatically — reducing diesel consumption and stabilising renewable-heavy microgrids. S.A.International supplies, configures and commissions DEIF EMS and hybrid controller solutions across Tamil Nadu and for export.
Multi-Source EMS Platform
PV + Wind + BESS + DG + Utility integration
Plant-level energy management with deterministic load sharing across renewables, storage and conventional generation. Modes include fuel-saver, zero-genset, peak-shaving, self-consumption, grid-forming and grid-following — switched automatically based on load, generation and tariff conditions. Native SCADA/BMS integration via Modbus TCP, IEC 61850 and OPC UA.

Frequently asked questions
What is a hybrid controller?
A hybrid controller (also called an energy management system or microgrid controller) coordinates multiple power sources — solar PV, battery storage (BESS), diesel/gas gensets and the grid — so they operate as one plant. The DEIF hybrid controller decides in real time how much each source contributes to maximise renewables and minimise fuel burn.
How much fuel can a PV-diesel-BESS hybrid controller save?
Savings depend on solar sizing, load profile and storage, but well-designed diesel-PV-BESS hybrids commonly cut fuel use substantially by prioritising solar and battery power and running gensets only when needed. We size and model each site before quoting.
Can the EMS work both grid-connected and off-grid?
Yes. The DEIF EMS supports seamless island (grid-forming) and grid-connected (grid-following) operation, with automatic mode switching based on load, generation and tariff conditions.
