DC Wiring

String Wiring

String wiring connects PV modules into efficient circuits designed for optimal voltage and energy flow. Nexus Solar Group routes and terminates string wiring with careful attention to shading, wire protection, and troubleshooting accessibility. Well-executed string wiring maximizes system output.

Combiners

Combiner box installations aggregate multiple string circuits cleanly and safely before delivering DC power to inverters. Nexus Solar Group ensures code-compliant terminations, labeling, and testing for every combiner installation. Organized combiners simplify system maintenance and monitoring.

Inverter Installation

Inverter installations are performed with precision to ensure smooth DC-to-AC energy conversion. Nexus Solar Group handles inverter mounting, terminations, grounding, and system integration to meet project specifications. Proper inverter setup improves energy capture and system reliability.

Expert Wire Management

Expert wire management prevents cable wear, shading issues, and long-term maintenance problems. Nexus Solar Group secures wiring with clips, conduits, and supports to maintain clean, efficient cable runs. Protecting cables improves system appearance, durability, and performance.

Harness

Pre-manufactured harness systems simplify field wiring and reduce labor costs. Nexus Solar Group installs harnesses to minimize string mismatch, voltage drop, and connection errors. Harness use leads to faster builds and higher installation quality.

Trunk Bus

Trunk bus wiring systems are installed to consolidate DC collection efficiently across large sites. Nexus Solar Group plans and routes trunk buses to minimize losses and support easy system maintenance. Proper trunk bus installation increases system scalability and performance.

DC Wiring Experts

DC wiring is at the heart of solar energy flow, and Nexus Solar Group brings unmatched precision to every wire, combiner, and inverter connection. Our teams specialize in high-efficiency string layouts, expert terminations, and advanced wire management techniques. We ensure each conductor is sized, routed, and secured to maximize performance and minimize long-term degradation.

From harness installations to trunk bus systems, we apply standardized, quality-controlled methods that improve consistency across utility-scale and C&I projects. Our wire management practices reduce shading risk, prevent abrasion, and allow for easier maintenance access down the line. Every cable run is designed to meet both NEC requirements and the real-world demands of field conditions.

Nexus Solar Group’s DC crews are trained to execute installations quickly without compromising accuracy. We use pre-fabrication, smart layout planning, and robust QA/QC processes to keep wiring clean, safe, and compliant. With our team, every connection counts—and every watt is protected.
