What battery storage systems does Alpha Devraj ESS build?
Alpha Devraj ESS builds LFP battery energy storage in three form factors: compact C&I cabinets (100–260 kWh), fully integrated 20ft containers (up to 6.25 MWh) and utility-scale grid blocks (20 MWh to GWh class). All three share one platform — liquid-cooled LFP with integrated BMS, fire suppression and remote monitoring.
C&I Cabinet
Compact and outdoor-rated. Storage that fits beside the factory, not a substation.
- Capacity
- 100–260 kWh
- Footprint
- ~1.3 m²
- Cooling
- Liquid / air
- Ingress rating
- Outdoor IP55
Best for: Demand charges, backup and behind-the-meter savings at commercial and industrial sites.

The workhorse. A fully integrated, liquid-cooled LFP system that ships, sites and commissions as one unit.
- Capacity
- Up to 6.25 MWh
- Enclosure
- 20ft ISO
- Cooling
- Liquid
- Cell options
- LFP 100 / 230 / 280 / 302 / 314 / 320 / 560 / 587 / 628 Ah
Best for: C&I at scale, renewable-energy firming and microgrids.

Containers arrayed and controlled as a single dispatchable grid asset — scalable to the gigawatt-hour.
- Capacity
- 20 MWh → GWh
- Configuration
- Modular container arrays
- Chemistry
- LFP / VRFB
- Duration
- 2–8 hr
Best for: Utility tenders, PPAs, ancillary services and renewable firming.

EMS, BMS and PCS — the systems inside
Every Alpha Devraj system runs three layers of electronics: a battery management system (BMS) protecting each cell, a power conversion system (PCS) moving energy between DC and AC, and an energy management system (EMS) deciding when to charge and discharge. Full detail lives on the technology page.

The difference between a system and a shipped box.
Plenty of containers land in India with a spec sheet and a shipping label. Here is what changes when the company that built it also has to live with it.
| What matters | Alpha Devraj ESS | Typical traded box |
|---|---|---|
| Cell sourcing & grading | Cells inspected, capacity-tested and matched on our own line | Pre-packed modules, provenance opaque |
| Assembly & testing | 100% of systems factory-acceptance-tested in Gujarat, records supplied | Sample testing at origin, paperwork only |
| Thermal management | Liquid cooling standard on containers | Air cooling unless you pay attention |
| System sizing | Sized from your tariff and load data, payback modelled first | Catalogue capacity, sizing is your problem |
| After-sales | 24×7 monitoring, O&M, augmentation planned into the design | Warranty claim process, spare parts by sea |
| Skin in the game | The same systems run on our own solar and wind projects | None — the box ships, the risk is yours |
Assurance
Warranted, guaranteed, watched.
Product warranty
Standard multi-year product warranty on every system — typically 5 years on cabinets and containers, extendable per project.
Performance guarantee
Capacity-retention guarantees available to 10 years, with degradation modelled up front and augmentation space reserved in the design.
24×7 remote monitoring
Every system ships with remote monitoring; our operations desk watches state of health, alarms and dispatch performance continuously.
Service & O&M
Long-term O&M contracts with defined response times, spares strategy and annual capacity testing — the asset stays bankable for its life.
Final warranty and guarantee terms are confirmed per project and chemistry, in writing, before you commit.
Standards
Engineered to global standards.
- IEC 62619 Cell & battery system safety
- IEC 62933 Grid-connected ESS performance & safety
- UL 9540A Thermal-runaway fire propagation testing
- ISO 9001 Quality management system
- ISO 14001 Environmental management
Certification status per standard is stated in each product datasheet.
