What CLN Energy manufactures
CLN Energy Limited manufactures lithium iron phosphate battery energy storage systems in India, at its facility in NEPZ, Noida, Uttar Pradesh. The range covers four formats and runs from 5.12 kWh for a single home up to 5.015 MWh in one 20 ft ISO container, with larger requirements met by placing containers in parallel.
The systems are supplied as complete units rather than as parts to be assembled on site. A delivered system brings together the LiFePO₄ battery modules, the power conversion system, the battery management system, thermal management, fire detection and the energy management software that runs it. The reason this matters commercially is narrow but important: when one supplier is responsible for the whole system, a fault has one owner, and the site is not left arbitrating between a battery vendor and an inverter vendor while the load sits without backup.
CLN Energy Limited is listed on the BSE SME platform under scrip code 544347. For a buyer raising a capital purchase order, that is a practical point rather than a promotional one: the supplier’s financial position is public and can be checked before the order is placed.
The range, by format and capacity
The format is usually decided by the site before the capacity is. A wall mounted unit suits a house; a container suits a substation; and the two are not interchangeable at any capacity. The table below is the current published range.
| Format | Voltage | Usable capacity | Typical application |
|---|---|---|---|
| Wall mounted | 25.6 V and 51.2 V | 5.12 kWh | Homes and small premises, where the battery hangs on a wall beside the inverter. |
| Stackable | 48 V | 4.8 kWh to 19.2 kWh | Homes and light commercial sites that expect to add capacity later, one module at a time. |
| Rack mounted, high voltage | 240 V to 720 V | 24 kWh to 226 kWh | Commercial and industrial buildings, telecom sites and data centre backup. |
| Containerised | System level | Up to 5.015 MWh in a 20 ft ISO container | Utility, grid support, solar firming and large industrial loads. |
Capacities between the published figures are reached by combining modules rather than by building a one-off cell arrangement, which keeps the spare parts and the service procedure the same as for a standard unit. Where a site needs more than one container, the systems are paralleled and run under a single energy management system.
Where the systems are built
Manufacturing is at NEPZ, Noida, in Uttar Pradesh. The systems are assembled and tested in India rather than imported complete.
That has one consequence worth stating plainly, because it is the question buyers actually ask. A system assembled here can have its specification changed for a particular site — the capacity, the voltage, the enclosure, the cooling arrangement — instead of the site being fitted to whichever configuration was shipped. It also means a service visit and a replacement module are a domestic matter rather than an import.
The standards the equipment is built to
The cells and systems are built to IEC 62619 and UL 1973 for battery safety, and UL 9540A for thermal runaway fire testing. IEC 62116 and IEC 61000 cover grid interaction and electromagnetic compatibility. CE and RoHS declarations apply to the equipment.
When comparing two suppliers, the useful document is the datasheet for the specific model, not the standards list on a website. A standard named at company level does not tell you which model was tested to it. Ask for the model datasheet and the test report reference; any manufacturer who builds to these standards will have both, and the request costs nothing to make.
Would you like the specifications for the range?
We will send the datasheets for the formats relevant to your site, with the capacities, voltages and the standards each model is built to.
Who these systems are built for
Four groups of buyer, and the format usually follows from which one you are.
- Commercial and industrial sites replacing or reducing diesel generator running, managing peak demand charges, or holding production through a supply interruption. These sites generally take high voltage rack mounted systems, sometimes containerised.
- Utility and grid-connected projects firming solar output, shifting energy to the evening peak, or providing grid support. These take containerised systems, often several in parallel.
- Telecom and data centre operators replacing lead-acid strings at tower and equipment sites, where the rack mounted format matches the existing cabinet.
- Homes and small premises wanting backup that does not need a generator, which the wall mounted and stackable formats cover.
How to take a requirement forward
A costed proposal needs three things from your side: the load in kilowatts, the number of hours of backup the site needs, and where the site is. With those, the system can be sized properly rather than quoted from a range.
If you are still at the stage of establishing a budget, the cost of a BESS in India page gives the published per kWh and per MWh ranges, and what sets a BESS quote explains the four components that move a quotation up or down and the red flags in one that looks too cheap. If you are comparing suppliers, our survey of battery energy storage manufacturers in India sets out who else operates in this market and on what basis.
Frequently asked questions
Is CLN Energy a BESS manufacturer in India?
Yes. CLN Energy Limited manufactures battery energy storage systems in India at its facility in NEPZ, Noida, Uttar Pradesh. The company builds lithium iron phosphate (LiFePO₄) systems in four formats — wall mounted, stackable, high voltage rack mounted and containerised — covering capacities from 5.12 kWh up to 5.015 MWh in a single 20 ft ISO container. CLN Energy Limited is listed on the BSE SME platform under scrip code 544347.
What capacity of battery energy storage system does CLN Energy manufacture?
The range runs from 5.12 kWh to 5.015 MWh. Wall mounted units are 5.12 kWh at 25.6 V or 51.2 V. Stackable units run from 4.8 kWh to 19.2 kWh at 48 V. High voltage rack mounted systems run from 24 kWh to 226 kWh between 240 V and 720 V. Containerised systems reach 5.015 MWh in a 20 ft ISO container. Larger requirements are met by placing containers in parallel.
Where is the manufacturing facility?
CLN Energy manufactures at NEPZ, Noida, in Uttar Pradesh, India. Systems are assembled and tested in India rather than imported complete, which is what allows the specification to be changed for a particular site instead of selected from a fixed catalogue.
Does CLN Energy supply containerised BESS?
Yes. The containerised system is built into a 20 ft ISO container and reaches 5.015 MWh. It integrates the battery racks, the power conversion system, thermal management, fire detection and the energy management system as one delivered unit, so the site receives a complete system rather than components to be assembled on location.
Which standards are the systems built to?
The cells and systems are built to IEC 62619 and UL 1973 for battery safety, UL 9540A for thermal runaway fire testing, and IEC 62116 and IEC 61000 for grid interaction and electromagnetic compatibility. CE and RoHS declarations apply to the equipment. The applicable standards for any particular model are stated on that model’s datasheet, which is the document to ask for when comparing suppliers.
Is CLN Energy a listed company?
Yes. CLN Energy Limited is listed on the BSE SME platform under scrip code 544347. For a buyer placing a capital order, that means the financial position of the supplier is a matter of public record and can be checked independently before a purchase order is raised.
What does a BESS from CLN Energy cost?
Cost depends on usable capacity, the power rating the site needs, and how the system connects to the existing supply, so it is quoted per project rather than from a price list. The budgeting ranges we publish, and the four things that move a quote up or down, are set out on our BESS cost page and our page on what sets a quote.
