The solar industry is rapidly evolving, and as photovoltaic systems scale up in size and voltage, balance-of-system (BOS) innovations are becoming critical. Nextracker’s NX PowerMerge™ eBOS Trunk Connector is a next-generation solution designed for utility-scale solar projects that demand high efficiency, lower installation costs, and long-term reliability. This advanced trunk connector is engineered to support the transition toward 2,000-volt solar arrays, making it one of the most future-ready DC connection systems available today.
Key Technical Features of NX PowerMerge™
- 2,000 V system readiness – Built to handle the new industry standard for high-voltage solar arrays, ensuring long-term compatibility.
- High ampacity performance – Designed for 400 A and above, enabling greater current capacity for large solar farms.
- Flexible tap capacity – Supports up to eight tap wires (6–8 AWG), consolidating more PV strings into a single trunk connection.
- Heavy-duty conductor compatibility – Works seamlessly with trunk conductors up to 1000 kcmil (MCM), ideal for large-scale deployments.
- U.S.-manufactured option – Meets domestic sourcing requirements for certain incentive programs, while also being globally available.
- Availability timeline – Available for purchase now, with deliveries scheduled from Spring 2026.
Why NX PowerMerge™ Matters for Utility-Scale Solar Projects
As solar plants continue to expand in size and complexity, traditional combiner box solutions often lead to excessive wiring, higher labor costs, and more potential failure points. The NX PowerMerge™ DC trunk connector addresses these challenges by:
- Reducing field connections – Fewer joints mean faster installation and lower risk of connection failures.
- Lowering balance of system (BOS) costs – By consolidating multiple string inputs into a single high-ampacity trunk, EPCs can cut both material and labor costs.
- Improving reliability – Expanded contact areas and optimized conductor interfaces ensure low resistance and reduced energy loss over decades of operation.
- Streamlining operations & maintenance – With fewer components to monitor, plant operators save on O&M expenses while improving uptime.
Market Context and Industry Evolution
Nextracker’s launch of the NX PowerMerge comes shortly after its acquisition of Bentek, a well-known name in solar electrical BOS solutions. This strategic move allows Nextracker to integrate proven trunk-bus technology into its global tracker and fixed-tilt solutions, creating a more holistic offering for EPCs and developers.
The push toward 2 kV DC solar systems is a significant industry milestone. Compared to 1,500 V systems, 2,000 V architectures enable longer strings, reduce the number of cables, and drive down overall LCOE (Levelized Cost of Energy). NX PowerMerge is among the first eBOS trunk connectors built specifically for this transition, giving utility-scale developers an edge in both performance and economics.
NX PowerMerge vs. Traditional Combiner Boxes
Traditional combiner boxes have long been the standard for PV array wiring, but they come with drawbacks such as higher installation costs, more failure points, and larger O&M footprints.
By contrast, the NX PowerMerge™ eBOS trunk connector:
- Cuts down the number of enclosures required across a site.
- Reduces cabling complexity and installation time.
- Lowers spare-parts requirements, since fewer combiner units are deployed.
- Provides scalability and flexibility for both solar tracker and fixed-tilt systems.
Pricing Insights and Availability
While Nextracker does not publish country-specific prices, the cost of the NX PowerMerge connector will vary based on:
- Project size and order volume.
- Regional manufacturing origin (U.S.-made vs. global supply).
- Additional options like surge protection or integrated fusing.
- Local import duties, shipping, and taxes.
As a reference point, similar heavy-duty trunk/combiner products in the market often range from the mid-hundreds to low-thousands of U.S. dollars per unit, depending on specifications. For an accurate quote, EPCs and developers should contact Nextracker’s sales team directly with project details.
EPC Checklist Before Specification
To ensure seamless deployment of NX PowerMerge in large solar farms, project owners and EPCs should:
- Request the official datasheet with torque specifications and wiring diagrams.
- Verify UL/IEC certifications and IP/IK enclosure ratings.
- Confirm ampacity derating curves for local temperature and altitude conditions.
- Determine the fusing and surge protection approach for project compliance.
- Obtain a formal quote that includes shipping, duties, and installation accessories.
Conclusion
The Nextracker NX PowerMerge™ eBOS Trunk Connector represents a significant step forward in utility-scale solar BOS innovation. With its 2 kV readiness, 400 A+ capacity, flexible tap design, and reduced connection architecture, it helps developers lower project costs, improve efficiency, and future-proof solar investments.
As the solar industry accelerates toward larger, higher-voltage systems, solutions like NX PowerMerge will play a central role in shaping the next generation of clean energy infrastructure.
