2.5MW / 5MWh Sunrange Utility-Scale Energy Storage System

*Deploying grid-scale storage is complex. Our integrated solution eliminates that complexity, offering a faster, more reliable path to profitability and grid support.

*Pre-Integrated for Rapid Deployment & Lower Risk: The system arrives as pre-assembled, containerized units—power conversion (PCS) and battery energy storage (BESS)—fully tested and ready for interconnection. This slashes commissioning time by up to 40% versus piecemeal solutions, reduces on-site integration risks, and delivers a faster ROI.

*Utility-Grade Performance with Advanced Grid Forming: Go beyond simple storage. Our system features grid-forming inverter technology capable of black start, voltage support, and precise frequency regulation (FR). It meets the most stringent grid codes (IEEE 1547, UL 1741 SA), making it a valuable, compliant grid asset.

*Unmatched Safety & Lifetime Value with LiFePO4: Built on inherently stable Lithium Iron Phosphate (LFP) chemistry, the system offers superior thermal safety and a longer lifespan (>6,000 cycles at 80% DoD). Combined with a multi-layer Battery Management System (BMS), it ensures maximum safety and the lowest Levelized Cost of Storage (LCOS) over its lifetime.

*Intelligent Software for Multi-Stack Revenue: Our proprietary Sunrange Energy Management System (EMS) doesn't just monitor—it optimizes. Automatically stack revenue streams: perform energy arbitrage (buy low, sell high), provide capacity services to the grid, and firm up your renewable generation to meet offtake agreements.

The Sunrange 2.5MW/5MWh system is more than an expense—it's a revenue-generating, future-proof infrastructure investment that provides energy security, grid stability, and financial predictability.

1. What makes a 2.5MW/5MWh system the right scale for our project?

This size is the benchmark for serious commercial, industrial, and grid-support applications. A 2.5MW/5MWh system (a 2-hour duration) is powerful enough to make a significant financial impact through peak shaving, demand charge reduction, and grid services, while still being modular and scalable for future expansion. It's the ideal scale for factories, data centers, large campuses, and renewable energy farms looking to achieve substantial energy cost savings and revenue generation.

2. Why is LiFePO4 (LFP) battery chemistry the best choice for this application?

Our systems utilize Lithium Iron Phosphate (LiFePO4) batteries, which offer the optimal balance of safety, longevity, and value for large-scale projects. LFP chemistry is inherently more stable, reducing thermal runaway risk, and delivers over 6,000 cycles at high depth-of-discharge. This translates to a longer operational life (15+ years) and a lower Levelized Cost of Storage (LCOS), ensuring a better return on your investment.

3. How quickly can we deploy this system?

Our solution is built on a pre-engineered, containerized platform. The system arrives in standard shipping containers with all critical components pre-integrated and factory-tested. This "Plug-and-Play" approach drastically reduces on-site construction time and complexity, enabling deployment and commissioning in a matter of weeks, not months, so you can start saving faster.

4. How does this system specifically help reduce my business's energy costs?

The system operates intelligently to cut your highest energy expenses. It automatically discharges stored energy during peak demand periods when utility rates are at their highest—a process known as peak shaving. For many businesses, this can reduce "demand charges" on their electricity bill by 30-50%, leading to rapid payback periods. It can also perform energy arbitrage, buying and storing low-cost energy (e.g., at night or from excess solar) to use during expensive daytime hours.

5. Can this system provide backup power during a grid outage?

Absolutely. Beyond financial optimization, the system is engineered for energy resilience. In the event of a grid failure, it can seamlessly island from the grid and provide backup power to your critical loads. For a 2.5MW/5MWh system, this can keep essential operations online for hours, ensuring business continuity and protecting against costly downtime.

6. What level of remote monitoring and control do we have?

You have complete oversight through our cloud-based intelligent monitoring platform. Access real-time data on state of charge, power flow, savings, and system health from any device. You can also set operational modes (e.g., prioritize cost savings or backup) and receive instant alerts, enabling proactive management with minimal on-site involvement.

7. What kind of support and warranty do you offer?

We stand behind our technology with comprehensive support. This includes a full 10-year performance warranty on the battery system and lifetime 24/7 remote monitoring. Our partnership extends beyond the sale with dedicated project management, detailed system design support, and optional long-term Operation & Maintenance (O&M) packages to ensure optimal performance for decades.
