SunWell Energy integrates SunWell inverters with 56kWh low-voltage ESS and 240kWh BESS for a Texas sports facility

As commercial energy storage adoption accelerates across the United States, sports facilities are becoming one of the fastest-growing application scenarios for battery energy storage systems (BESS).

To improve energy reliability, reduce electricity costs, and strengthen backup power capability, a sports facility in Texas recently deployed a complete hybrid energy storage solution powered by SunWell Energy.

The project includes:

• A 240kWh high-voltage commercial ESS system
• A 56kWh low-voltage lithium battery storage system

Together, the two systems create a flexible and scalable commercial energy infrastructure capable of supporting multiple operational requirements within the venue.

Additional High Voltage ESS Deployment

In addition to the low-voltage system, the facility also deployed a larger 240kWh SunWell Energy high-voltage ESS system for broader commercial energy management requirements.

The combination of high-voltage and low-voltage ESS architectures allows the sports facility to build a layered energy strategy capable of supporting both critical loads and large-scale energy optimization.

Why Sports Facilities Need Battery Energy Storage

Modern sports venues consume large amounts of electricity throughout daily operations.

Typical power consumption includes:

• Stadium lighting
• HVAC systems
• Electronic displays
• Security systems
• Audio systems
• Gym equipment
• Event-related peak loads

In Texas, commercial electricity pricing and grid stability challenges make energy storage systems increasingly valuable for facility operators.

Battery ESS systems help sports facilities:

• Reduce utility demand charges
• Maintain uninterrupted operations
• Improve emergency backup capability
• Optimize energy usage
• Support future solar integration

Flexible Low Voltage ESS for Distributed Energy Applications

The 56kWh low-voltage ESS was specifically designed to support flexible power management within the sports facility.

Compared with large-scale centralized storage systems, low-voltage battery solutions provide several unique advantages:

Modular Expansion

The system uses four 14kWh lithium batteries connected in parallel, enabling future expansion based on operational requirements.

Wide Inverter Compatibility

The batteries are compatible with U.S. market hybrid inverters, supporting stable communication and intelligent energy management.

Simplified Installation

Low-voltage systems offer easier deployment and maintenance for distributed commercial applications.

Reliable Backup Power

Critical equipment inside the sports venue can continue operating during power outages or grid fluctuations.

The system provides stable power support for commercial environments requiring reliable daily cycling and backup energy capability.

Integrated High Voltage + Low Voltage ESS Architecture

One of the highlights of this Texas sports facility project is the deployment of both high-voltage and low-voltage battery systems within the same commercial environment.

240kWh High Voltage ESS

The previously installed SunWell Energy R60 high-voltage ESS system serves larger commercial energy management functions, including:

• Peak shaving
• Large-scale energy storage
• Demand charge reduction
• Commercial load balancing

The high-voltage system integrates with SunWell hybrid inverters and utilizes certified commercial battery technology.

56kWh Low Voltage ESS

The low-voltage system provides:

• Flexible distributed backup power
• Supplemental load support
• Critical equipment protection
• Enhanced operational redundancy

Together, the two ESS systems create a more resilient and intelligent commercial energy ecosystem.
