Background: Why Data Center Need Energy Storage
As India’s digital economy expands, IT data center must manage rapidly rising electricity demand while guaranteeing uninterrupted operation. For these energy-intensive, mission-critical facilities, even a brief power interruption can disrupt essential services and threaten business continuity.
Solis addressed this challenge by commissioning its first EverCore Energy Storage System (ESS) project in India — an integrated solar-plus-storage solution for a software IT data center in Chennai, Tamil Nadu, developed in collaboration with Inforce Engineering Solutions LLP (Inforce Solar).
What Is SolisStorage EverCore?
SolisStorage EverCore is the commercial and industrial (C&I) battery energy storage product line. Each EverCore unit delivers 261 kWh of storage and is engineered to pair with Solis hybrid inverters, allowing businesses to capture surplus solar energy and dispatch it when needed. In this project, four EverCore units run in parallel to provide reliable, flexible backup and peak-shaving capacity for the data center.
System Architecture & Key Specifications
| Component | Specification |
| Rooftop solar PV | 870 kW (615 Wp TOPCon modules) |
| Battery energy storage | 500 kW power / 1.04 MWh capacity |
| EverCore storage units | 4 × 261 kWh (parallel configuration) |
| Hybrid inverters | 4 × Solis S6-EH3P125K |
| Implementation partner | Inforce Engineering Solutions LLP (Inforce Solar) |
| Primary benefit | Higher renewable self-consumption + diesel reduction |
During daylight, the rooftop array generates solar power; surplus energy is stored in the EverCore batteries and released when demand peaks or grid conditions require — maximizing on-site renewable self-consumption throughout daily operations.
How the Project Reduces Diesel Dependency
Data centers have traditionally relied on diesel generators for backup power. Rising fuel costs and corporate sustainability targets are pushing operators toward cleaner alternatives. By integrating solar PV with battery storage, this system adds a low-carbon energy resource that can reduce diesel-generator runtime under suitable operating conditions.
·Renewable optimization — maximizes on-site solar utilization
·Peak-demand management — supplies stored energy during high-tariff periods
·Operational flexibility — enables smarter, automated energy scheduling
·Lower carbon impact — cuts fuel consumption and diesel-generator usage
Why This Matters for India’s C&I Storage Market
India’s commercial and industrial sectors are rapidly adopting renewable energy to manage rising demand, grid instability, and sustainability commitments. The successful Chennai deployment demonstrates how integrated solar-plus-storage supports critical infrastructure and helps businesses extract more value from renewable investments. By combining hybrid-inverter technology, intelligent energy management, and modular storage design, Solis is expanding access to resilient, lower-carbon power for Indian industry.
Solis’s Commitment
“As India transitions toward a cleaner, more resilient energy future, Solis remains committed to delivering innovative energy-storage solutions that give industries smarter, safer and more sustainable power management.”
