Voltage Energy Achieves First-Ever 2 kV EBOS Certification from UL Solutions

Voltage Energy Achieves Groundbreaking 2 kV EBOS Certification

In a major milestone for solar technology, Voltage Energy Group has secured the first-ever 2 kV EBOS (Electrical Balance of System) certification from UL Solutions, as announced on December 15, 2025. This certification recognizes Voltage Energy's commitment to facilitating the transition to more advanced photovoltaic (PV) systems, marking a significant advancement in the solar energy sector.

The industry is increasingly shifting from 1500 VDC (volts direct current) to 2 kV systems in large-scale solar projects, acknowledging various benefits, such as improved energy output, lower capital costs, and enhanced long-term reliability. The EBOS solution from Voltage Energy encompasses full system integration, covering their LYNX®, IBEX®, IBEX PLUS®, and ALEX® product lines, all optimized for 2 kV applications.

Importance of 2 kV Systems

Angel López, Voltage Energy's Director of Quality, emphasized the significance of this certification, stating, "Receiving UL certification for our 2 kV full EBOS solution demonstrates our commitment to providing technologies that assist the industry in scaling next-generation PV designs." Transitioning to a 2 kV system goes beyond merely upgrading components; it necessitates a coordinated effort across the entire value chain. This includes joint validation of modules, inverters, and EBOS, aligned with rigorous standards and cross-testing, all aimed at reducing variability in field implementations.

The certification process involved substantial testing by UL Solutions to ensure compliance with the strict requirements set for 2 kV systems. Evan Xiao, the regional general manager of UL for Asia, commented on the importance of this accomplishment: "Unified system validation and repeatable installation practices are essential for scaling the 2 kV ecosystem. Voltage Energy's certification underscores an ongoing investment in system integration and verification, providing the market with a clear benchmark for evaluating reliable 2 kV implementations."

Moving Forward with Support and Collaboration

Following the certification, Voltage Energy plans to extend further support to Engineering, Procurement, and Construction (EPC) contractors and developers by collaborating on design, technical integration, and training. This proactive approach aims to help teams adopt consistent engineering and installation practices for 2 kV projects, fostering an environment conducive to the widespread adoption of this technology.
