For commercial businesses, maintaining a reliable energy supply is crucial to continuous operation. Unlike the storage of fossil fuels, energy derived from renewable resources has a unique challenge: it cannot be easily stored for later use. As a result, battery energy storage systems have become crucial for capturing energy at its source and delivering it to the grid.
The Sol-Ark L3 Series LimitLess Lithium Battery Energy Storage System is designed to provide a dependable and resilient solution for business owners seeking more energy independence. This energy storage system offers technical advantages that address common energy challenges businesses face today: seamless power backup, industry-leading safety features, and scalability for larger energy demands.
What is a Battery Energy Storage System (BESS)?
A battery energy storage system is an electrochemical device that collects energy from the main electrical grid or other renewable energy sources. This allows businesses to achieve more energy independence by discharging this stored energy when it’s needed, providing backup power during outages. It can also be used to reduce electricity demand on the grid, especially during peak periods.
Seamless Backup Power During Grid Outages
When the main electrical grid fails, business operations often halt, causing potential losses in productivity, revenue, and customer satisfaction. The Sol-Ark L3 Series provides uninterrupted power during grid outages through its advanced lithium-ion battery storage and inverter technology. This seamless transition to backup power is achieved with minimal delay (a 5ms transfer rate), meaning critical systems stay operational, from lighting to computer systems and even heavy machinery. Unlike traditional diesel generators that require startup time, this lithium battery system activates almost instantly, ensuring businesses stay powered when they need it most.
Sol-Ark’s battery management system (BMS) is designed to deliver efficient discharge rates without compromising battery life or stability. This allows the L3 Series BESS to meet sudden surges in power demand, a key feature for industries like healthcare and manufacturing, where downtime can have serious repercussions. The robust design and quick discharge capability ensure that even during prolonged outages, essential systems remain powered, safeguarding productivity and operational integrity.
Industry-Leading Battery Energy Storage Safety Features
Safety is a top priority for business owners. That’s why the Sol-Ark L3 Series meets and exceeds the standards and certifications needed such as UL 1973, UL 9540, and UL 9540A, which ensure superior system safety and operability.
Standards & Certifications
- UL 1973: Assess aspects such as fire resistance, electrical stability, and overall thermal safety; batteries are rigorously tested for their ability to withstand thermal and electrical stresses without catching fire, leaking, or short-circuiting.
- UL 9540: Certifies the entire energy storage system (ESS), all the components, work together seamlessly and safely: battery management system (BMS), inverters, and controls
- UL 9540A: Large-scale fire safety test standard testing for fire containment, ensuring that any potential thermal runaway in a single battery cell or module does not ignite surrounding cells or cause a broader system fire.
Both L3 Series BESS models have a built-in local management system that can manage and monitor voltage, current, and temperature that ensures high performance and safety features. The BMS plays a crucial role in balancing the battery’s capacity and extending the system’s cycle life.
HVAC & Aerosol-Based Fire Suppression
The L3 Series HVR battery energy storage system, which is our outdoor solution, incorporates built-in aerosol-based fire suppression systems within both the cabinet and battery modules to provide a strong defense against thermal runaway events. The aerosol canister would rapidly deploy and fill the battery module interior with the non-toxic agent to suppress any potential fire before spreading. The aerosol canister, located in the cabinet, is triggered by sophisticated fire detection sensors that monitor for smoke, heat, and gas, which ensures a response to any abnormal conditions. In addition to fire safety, our integrated HVAC system manages the interior climate of the cabinet, offering cooling, heating, and dehumidification to maintain optimal battery performance.
Scalable for Increased Commercial Business Power
Sol-Ark’s BESSs are designed for scalability, allowing multiple indoor and outdoor BESS units to be connected in parallel to meet higher demands. Businesses can parallel up to 16 L3 HV-60K/40K units per inverter and up to six (6) L3 HVR units per inverter as their energy needs grow.
Several customers have successfully met their energy needs by incorporating multiple L3 HVR-60 Battery Energy Storage Systems (BESS). For example, Pinder Tile in the Bahamas installed an integral solar and energy storage system using three Sol-Ark 60k inverters and four L3 HVR-60 BESS, this impressive installation allows them to achieve their decarbonization goals while significantly reducing operational costs.
Finally, the rigorous testing and certification to UL standards for the L3 BESS solutions and final assembly provide the most reliable option in the commercial and industrial applications market. Our customers can meet their renewable energy goals, sustainability, and power their business with reliable energy storage technology that can be expanded according to their demands.
How The Sol-Ark L3 Series BESS Compares to Other Commercial Solutions
The Sol-Ark L3 Series LimitLess Lithium Battery Energy Storage System offers a powerful solution for commercial businesses aiming to enhance their energy resilience, smooth out renewable energy fluctuations, and reduce dependency on the grid. With seamless backup, consistent energy smoothing, and reduced reliance on external power, the Sol-Ark L3 stands out as a forward-thinking investment in business continuity and energy independence.
