Battery Energy Storage System (BESS)
Containerised, grid-tied storage for utilities, C&I sites and renewable plants.
- Voltage range
- 600V – 864V DC, 3-phase AC output 400/415V
- Chemistry
- Lithium Iron Phosphate (LiFePO4 / LFP)
- Warranty
- 10-year performance warranty, ≥ 80% capacity retention
EcoSpark BESS platforms combine LiFePO4 racks, a power conversion system, thermal management and an EMS/BMS stack into a single commissioned unit — sized from a 50kWh commercial cabinet to multi-megawatt containerised blocks.
Systems operate in grid-tied or island mode, in parallel with a diesel generator, or stacked alongside additional BESS units as demand grows — with no forklift upgrade of the control layer required.
Built for the realities of Gujarat's grid: voltage fluctuation ride-through, high ambient temperature operation, and compliance with utility interconnection requirements for GETCO, PGVCL, DGVCL, UGVCL and MGVCL circles.
Built into every BESS unit.
Integrated EMS + BMS + SCADA
One control layer coordinates cell health, power flow and grid signals, with remote monitoring built in from day one.
Multi-layer protection
Cell, module and system-level OVP/UVP/OCP/OTP protection, with optional gas, aerosol or water-mist fire suppression.
Island-mode ready
Runs standalone during a grid outage, then resynchronises automatically once utility power is restored.
Active thermal management
Air-cooled as standard, liquid-cooled option for high-cycling or high-ambient deployments.
Outdoor-rated enclosure
IP54–IP65 10ft / 20ft containers engineered for direct outdoor installation with minimal civil work.
Designed to scale
Add strings or containers in parallel as load grows, without replacing the original investment.
Application-matched, not one-size-fits-all.
A fully integrated, plug-and-play energy storage platform — from rack-mount cabinets to outdoor-rated containers — built to shift load, firm renewables, and keep critical infrastructure online.
- Peak shaving & demand charge reduction for industrial plants
- Solar & wind firming for renewable IPPs
- Substation and switchgear DC backup
- Microgrids for campuses, ports and industrial parks
- Diesel-genset offset for continuous-process factories
