DFUN Successfully Concludes Its DCW Madrid 2026 Exhibition

DFUN successfully concluded its exhibition at Data Centre World Madrid 2026, held on 4–5 November at IFEMA Madrid. At Stand 5C66, our team connected with data center operators, partners, and industry colleagues to discuss practical pathways from periodic inspection to continuous, data-driven battery monitoring.

Three Solutions for Data Center Power Reliability

Throughout the two-day event, DFUN showcased three solution areas addressing different layers of data center power infrastructure:

Battery Health Monitoring Solutions

DFUN’s battery monitoring systems provide cell-level visibility into voltage, temperature, internal resistance, and state of health. By tracking trends against each battery’s installed baseline, operators can identify weak cells earlier and make replacement decisions based on data rather than fixed schedules.

Array Cabinet Solution

The array cabinet solution supports centralized monitoring and management of battery arrays in UPS rooms. It helps operators maintain consistent visibility across multiple strings and cabinets, reducing the need for manual spot-checks and improving maintenance planning.

Busbar Monitoring Solution

Busbar monitoring extends visibility beyond the battery itself — covering the power distribution path that connects batteries to critical loads. This helps detect abnormal conditions in the busbar system that could affect overall power reliability.

Together, these solutions reflect DFUN’s focus on supporting the full power path in data centers, from individual battery cells to the distribution infrastructure that keeps IT equipment running.

Conversations on Moving from Periodic Inspection to Continuous Monitoring

Many visitors to Stand 5C66 shared a common challenge: backup batteries are often inspected on a fixed schedule, yet degradation can occur between inspections without obvious warning signs. A battery string may appear normal on overall voltage while individual cells are already drifting.

DFUN’s team discussed how continuous monitoring addresses this gap by providing real-time and historical data on every battery, enabling operators to:

• Detect weak or abnormal cells before they affect the string.
• Track internal resistance and temperature trends over time.
• Prioritize maintenance and replacement based on actual battery condition.
• Integrate battery data with existing DCIM, BMS, or SCADA environments.

These conversations reinforced that data center operators are increasingly looking for monitoring solutions that are practical to deploy, scalable across sites, and capable of delivering actionable information rather than overwhelming alarm noise.

Meet the DFUN Team

Our team at Stand 5C66 welcomed a steady flow of visitors across both days, allowing for detailed technical discussions with data center operators, power system integrators, and industry partners. From battery-level monitoring to array cabinet and busbar solutions, the conversations reflected a shared interest in improving visibility and reliability across critical power infrastructure.

The team also took the opportunity to exchange insights with partners and industry colleagues, reinforcing DFUN’s commitment to supporting the data center ecosystem with reliable battery monitoring and management technologies.

Thank You to Everyone Who Visited Stand 5C66

DFUN extends sincere thanks to the Data Centre World team for organizing a well-run event, to partners and customers who made time to meet us in Madrid, and to everyone who stopped by Stand 5C66 to share their challenges and requirements.

For those who were unable to visit during the show, DFUN remains available to continue the conversation. Whether you are planning a new battery monitoring deployment or looking to improve visibility across existing UPS battery infrastructure, our team is happy to discuss your specific requirements.
