Trunk Bus Solution

A fully customizable large-power collection system, engineered for performance, simplicity, and reliability.

Simplified System Design

Voltage's Trunk Bus Solution replaces point-to-point wiring with a centralized backbone for a cleaner layout and faster installation.
Centralized Power Collection

The Trunk Bus combines power from multiple PV strings via lateral harnesses, cutting conductor count and simplifying field deployment.
High-Capacity Power Backbone

A large-gauge, direct conductor path efficiently delivers power to inverters minimizing losses and improving system reliability.
