Good, better, BESS: Polarium Battery Energy Storage System Explained

In an era where energy security and sustainability are more crucial than ever, businesses need flexible, reliable, and efficient solutions to meet their energy demand. Polarium Battery Energy Storage System (BESS) offers exactly that—a scalable and intelligent solution designed to store and manage energy for commercial and industrial applications. 

We sat down with Samuel Wingstedt, Product Manager, BESS at Polarium’s Commercial & Industrial (C&I) Business Area, to learn more about how this cutting-edge technology can transform how businesses approach energy consumption.

Can you describe Polarium’s BESS?
Samuel Wingstedt: Polarium Battery Energy Storage System (BESS) is a flexible and scalable solution for storing energy from various sources. Designed with modular lithium-ion batteries and inverters, it supports energy security, renewable integration, and electrification. By adding our Energy Management System, the BESS optimizes consumption, reduces costs, and enables revenue generation—all automatically and without interruption.  

What makes Polarium’s BESS stand out in the market?
Samuel: Polarium Battery Energy Storage System (BESS) has a modular and scalable design. It can seamlessly integrate with various energy sources—like solar or wind—and even be incorporated into existing infrastructure. Our system grows with your business, so whether you’re scaling up your operations or aiming to transition to renewable energy, Polarium has you covered. Safety and reliability are standout features and top priorities for us. Polarium BESS includes several key features to ensure that it operates safely, even in demanding environments. For instance, our Battery Management System (BMS) ensures each battery operates efficiently and is protected from potential issues like overheating or discharge problems. Our Propagation Protection System (PPS) rapidly detects and prevents any thermal event in a battery module from escalating. This system has been tested to the highest standards (IEC 62933-2) and provides an extra layer of safety, ensuring that your energy storage is as safe as it is efficient. 

What kind of integration options do you offer for businesses looking to implement BESS?
Samuel: We understand that each business is unique, so we offer flexible integration options to fit various needs. You can opt for a turnkey solution, where we provide the entire system, or you can choose to integrate BESS into an existing infrastructure.  

For businesses looking for hands-off management, we also offer Fleet Management, which allows you to remotely monitor, update, and configure your system, ensuring it operates at peak performance around the clock. 

What are the key configurations of Polarium BESS?
Samuel: Polarium BESS is available in two main configurations to cater to different energy needs: Power BESS and Energy BESS. 

• Energy BESS: This configuration is ideal for businesses needing large-scale storage and energy flexibility. With 8 batteries and 8 inverters (up to 1,120 kWh), it’s perfect for load shifting, peak shaving, and providing ancillary services to the grid. 

• Power BESS: On the other hand, for businesses with lower energy demands, the Power BESS, with 4 batteries and 8 inverters (up to 560 kWh), offers a more compact yet powerful solution. 

Both configurations are scalable, so as your energy needs grow, your system can grow with you. 

How does Polarium support businesses after installation?
Samuel: Once your BESS is up and running, we offer continuous support to ensure it continues to meet your business’s needs. With Polarium Fleet Management, we can monitor, control, and optimize the performance of your entire battery fleet remotely. Our predictive and preventive management systems enable us to detect and address potential issues before they become problems, reducing downtime and maximizing the system’s lifespan. 

Additionally, our Energy Management System (EMS) helps businesses configure and aggregate energy usage to make the most out of every charge and discharge cycle. Whether you’re looking to reduce costs, improve energy efficiency, or even generate revenue, our team is here to provide ongoing support. 

How can businesses get started with Polarium BESS?
Samuel: Getting started is simple. Our team works closely with you to understand your specific energy needs and goals. From there, we design and implement a solution that meets your requirements—whether you need a small setup or a larger, integrated system. Thanks to our vertical integration, we can offer end-to-end solutions, from development and manufacturing to installation and aftercare. We make it easy to own, operate, and scale your energy storage system.
