Solutions — by use case
What is a battery-backed microgrid?
A microgrid is a self-contained power system — typically solar, storage and backup generation — that can run connected to the grid or islanded from it. The battery is its backbone: it balances supply and demand in real time. Alpha Devraj ESS designs microgrids for industrial campuses, remote sites and critical facilities.
How it works
Watch it run.
Why sites build microgrids
Three reasons dominate: reliability (ride through grid outages without interruption), cost (maximise cheap on-site solar, minimise peak imports), and access (remote sites where grid supply is weak or absent). A battery-backed microgrid addresses all three with one architecture.
The battery’s role
In a microgrid the battery does more than store energy: it sets frequency and voltage when islanded, bridges the gap between an outage and generator start, and smooths solar variability so sensitive loads never notice. Grid-forming inverter capability is what separates a true microgrid from a simple backup system.
Common questions
Can a microgrid run indefinitely off-grid?
With enough generation and storage, yes — but most customers choose a hybrid design: grid-connected for normal economics, islanding for outages. The right balance is set by how long you need to ride through and what that continuity is worth.
