In renewable energy systems, efficiency is more than just energy conversion—it's also about optimizing structure, cost, and materials. Traditional copper conductors, though highly conductive, impose weight and cost burdens in large installations. E91E aluminum busbar from Xinyi offers a smart, lightweight solution, specifically designed for high-current applications in solar, wind, and battery energy storage systems (BESS).

Lightweight Advantage in Structural Design

Wind turbine nacelles and solar inverter enclosures are height- and space-sensitive structures where weight matters. E91E aluminum is roughly one-third the density of copper, significantly reducing the mechanical load on mounting systems and supports. This translates into simpler engineering designs, easier transportation, and lower installation costs—especially in remote or elevated installations.

High Electrical Conductivity for Power Flow

Despite its lower density, E91E achieves ≥61.5% IACS conductivity, making it highly suitable for renewable power transmission applications. By optimizing busbar width and thickness, aluminum can match the current-carrying capacity of copper while offering better thermal dissipation due to its higher volume-to-weight ratio.

Ideal for Solar Inverters and Combiner Boxes

E91E aluminum busbars are widely used in PV inverter cabinets, DC combiner boxes, and AC distribution panels. Their lightweight properties reduce stress on electrical joints and enclosures, while surface treatments such as tin plating or insulation film improve contact reliability under outdoor conditions.

Wind Power Systems: From Tower Base to Nacelle

In wind turbines, busbars often run vertically along towers or are integrated into rotating assemblies. E91E aluminum reduces the torque and weight involved, improving safety and long-term performance. Its corrosion-resistant coating ensures durability in coastal or offshore environments.

Battery Storage and Grid Integration

Battery Energy Storage Systems (BESS) require robust and scalable power connections. E91E aluminum busbars from Xinyi support modular installation with consistent conductivity, low weight, and high formability—making them easy to customize for containerized or cabinet-type energy storage units.

Environmental and Economic Benefits

Besides weight reduction, E91E aluminum busbars are more sustainable. Aluminum production has a lower carbon footprint than copper, and the material is fully recyclable. For renewable energy developers aiming for full lifecycle sustainability, aluminum offers both ecological and economic advantages.
