Grid forming vs grid following BESS is the most important inverter control decision in battery storage today. In April 2025, Spain and Portugal lost power within minutes. The cascade knocked out supply across most of the Iberian Peninsula. Investigators found one root cause: too many grid-following inverters and not enough grid-forming ones to arrest the frequency […]
What Are BESS Communication Protocols? BESS communication protocols are the rules that let every part of a battery storage system share data. So without them, batteries, inverters, and grid systems cannot work together. Each device in a BESS speaks a different digital language. But a shared protocol gives them a common way to talk. For […]
Battery energy storage systems are expanding rapidly across the United States. As projects grow larger, safety requirements are becoming stricter. Because of this, developers must understand modern ESS codes and standards before starting a project. Today, battery storage compliance affects: In addition, many utilities and authorities now require proof of compliance before approving a project. […]
What Is BESS Grid-Following? BESS grid-following is the most widely used inverter control mode in battery storage today. In simple terms, a grid-following (GFL) inverter locks its output to the existing grid voltage and frequency. Because of this, the battery system follows the grid — not the other way around. This approach works well in […]
BESS grid-forming technology is transforming how power grids stay stable. As renewable energy now accounts for more than 80% of new global capacity additions, grids are losing the mechanical inertia they once relied on. BESS grid-forming technology solves this problem directly. It lets batteries create their own voltage and frequency — rather than following the […]
Most facility managers focus on battery capacity or inverter size when evaluating a BESS. However, one component quietly determines whether the whole system works as promised. That component is the Static Transfer Switch (STS). It is the device that makes power transitions invisible to your equipment — and your operations. In this guide, we cover […]
EMS architecture is the control backbone of modern battery energy storage systems. It helps batteries operate safely, efficiently, and reliably. In addition, EMS architecture improves grid stability, renewable energy integration, and power management. Today, battery storage systems support much more than backup power. They also help utilities balance electricity demand and stabilize renewable energy output. […]
Introduction: Why ACIR LFP Battery Testing Matters ACIR LFP battery testing is critical in Battery Energy Storage Systems (BESS). It checks each cell before assembly. As a result, it prevents hidden defects early. In contrast, DCIR measures performance under load. However, ACIR focuses on physical structure. Therefore, it gives a fast and clear view of […]
ACIR gives us a snapshot of a cell’s physical integrity. However, DC Internal Resistance (DCIR) tells us how that cell performs when the grid calls for power. Understanding DC Internal Resistance LFP metrics is critical for managing grid-scale BESS. ACIR provides a snapshot of physical integrity. However, DCIR determines performance during immediate power demands This […]
The debate over Sodium-ion vs LiFePO4 winter performance has reached a tipping point in 2026. While Lithium Iron Phosphate (LiFePO4) is the industry leader, its struggles in the cold are well-known. Consequently, many users now want better options for cold weather. As energy storage expands, Sodium-ion (Na-ion) is emerging as a top choice. In this […]
