Battery Energy Storage for Indian Businesses
Store your power. Cut your bills. Keep running.
Symbroj Cleantech designs, supplies and installs commercial battery energy storage systems from 50 kWh to 500 kWh. We help Indian factories, offices, hospitals and campuses lower peak-demand charges, reduce diesel generator use and get more value from their rooftop solar.
- End-to-end EPC
- Lithium iron phosphate (LFP) cells
- Remote monitoring
- DPIIT-recognised startup
Charge from the grid off-peak or from surplus solar, then run your loads through peaks and outages.
Your electricity bill is paying for problems a battery can solve
For most Indian businesses, the cost of power is not just the units consumed. It is the peak-demand charges, the time-of-day tariffs, the diesel burnt during outages and the solar energy that goes to waste. A battery energy storage system tackles all four at once.
High peak-demand charges
Short spikes in load set your contract demand and your monthly fixed charges. A battery covers those peaks so the grid never sees them.
Time-of-day tariffs
Many state DISCOMs charge more for power in peak hours. Charge the battery when power is cheap and use it when it is expensive.
Diesel generator costs
DG power is costly, noisy and polluting. A battery takes over during short outages and lets the generator run less, or not at all.
Wasted solar
Rooftop solar peaks at noon, but your demand may not. Storage moves that energy to the evening, so you use more of what you generate.
Downtime and power quality
Voltage dips and short outages stop machines and damage equipment. A battery switches over in milliseconds and keeps critical loads running.
Battery prices have fallen sharply over the last few years, and lithium iron phosphate technology has made storage safe and long-lasting. For many C&I sites, the numbers now work.
Storage sized for your site, from 50 kWh to 500 kWh
Every system we deliver is engineered around your actual load profile, not a catalogue size. We work with established battery manufacturers and integrate the cells, battery management system (BMS), power conversion system (PCS) and energy management system (EMS) into one working solution.

One battery, many ways to save
Peak shaving
Covers short load spikes so your maximum demand, and your fixed charges, stay lower
Time-of-day arbitrage
Charges in off-peak hours and discharges in peak-tariff hours
Solar self-consumption
Stores surplus daytime solar for use in the evening or at night
DG replacement and reduction
Takes over from the diesel generator during outages, cutting fuel and maintenance costs
Backup power (UPS-grade)
Keeps critical loads such as servers, cold chains and production lines running through outages
Power quality
Smooths voltage dips and frequency fluctuations that trip sensitive equipment
Load expansion without upgrade
Lets you add equipment without raising your sanctioned load or upgrading the transformer
One partner from first audit to final handover
As your EPC partner, Symbroj Cleantech takes responsibility for the whole project, so you deal with one team and one point of accountability.
- 1
Energy audit and load study
We study your electricity bills, load data and DG logs to understand where the money is going.
- 2
Engineering and sizing
Our engineers size the battery and inverter, design the single-line diagram and calculate the savings and payback for your site.
- 3
Techno-commercial proposal
You get a clear proposal covering the system design, costs, expected savings and payback, so you can decide with confidence.
- 4
Procurement
We source cells, PCS and EMS from vetted manufacturers, and handle quality checks before dispatch.
- 5
Installation and commissioning
Our team installs, integrates with your grid, solar and DG systems, tests and commissions the system.
- 6
Monitoring and support
Remote monitoring, periodic health checks and an annual maintenance contract keep the system performing for years.

Battery storage questions, answered
A BESS stores electricity in rechargeable batteries and releases it when you need it. It combines battery modules, a battery management system, an inverter and control software in one unit.
It depends on your tariff, demand charges, outage hours and solar generation. After a free load study, we give you a site-specific savings and payback estimate before you commit.
For short and frequent outages, yes, in many cases. For long outages, a battery can work alongside the DG so it runs far less, cutting fuel and maintenance costs.
No. A battery saves money on its own through peak shaving and time-of-day tariffs. With solar, the savings increase.
We recommend lithium iron phosphate (LFP). It is thermally stable, safe for indoor and commercial use, and offers a long cycle life.
Quality LFP systems are typically rated for thousands of charge cycles and around 10 years or more of service, depending on usage and the manufacturer's warranty terms.
A 100 kWh cabinet needs roughly the floor space of a large refrigerator, plus clearance. We confirm the exact footprint during the site visit.
Once equipment is on site, most C&I systems are installed and commissioned within days to a few weeks, depending on size and approvals.
