1500VDC Solar DCDB Panel: Maximize Performance, Ensure Safety for Utility-Scale PV

Product Overview

The 1500VDC Solar DC Distribution Box (DCDB) Panel is the critical link in high-voltage photovoltaic (PV) systems, designed to aggregate DC power from multiple solar strings while providing robust protection and efficient distribution to your central or string inverter. Engineered for the demanding requirements of utility-scale, large commercial, and industrial solar projects, this DCDB panel ensures maximum energy harvest, uncompromising safety, and long-term reliability in even the harshest environments.

Optimized for 1500VDC systems, our DCDB panel significantly reduces current, minimizes resistive losses, and allows for longer string lengths, thereby reducing Balance-of-System (BOS) costs and enhancing overall system efficiency.

Key Features & Benefits

1. 1500VDC High Voltage Capability

• Optimized for Modern PV Systems: Designed specifically for the latest generation of high-voltage solar arrays, supporting higher power ratings and reducing overall system complexity.
• Reduced Current, Enhanced Efficiency: Operating at 1500VDC significantly lowers current, minimizing I²R losses across the system and maximizing energy yield.
• Cost-Effective Cabling: Enables longer string lengths and fewer combiner boxes, leading to reduced cable requirements and associated installation costs.

2. Advanced Multi-Level Protection

• Individual String Overcurrent Protection: Equipped with high-rupturing capacity (HRC) fuses (or optional DC circuit breakers) for each individual string input, safeguarding against overcurrents and short circuits.
• Integrated Surge Protective Devices (SPDs): Includes Type 2 (or optional Type 1+2) surge arresters, offering robust protection against lightning strikes and switching overvoltages, extending the lifespan of valuable PV components.
• Load-Break DC Disconnector/Isolator: A high-capacity, lockable DC disconnector switch provides safe and reliable isolation of the entire DC array, crucial for maintenance, troubleshooting, and emergency shutdowns.
• Reverse Current Protection: Diodes or appropriate circuit design prevent reverse current flow, protecting modules and ensuring system stability.

3. Robust & Weatherproof Enclosure

• Superior Durability: Constructed from high-quality, UV-stabilized polycarbonate or powder-coated galvanized/stainless steel, ensuring exceptional resistance to corrosion, impact, and extreme weather conditions.
• IP65/IP66 Rated: Provides comprehensive protection against dust ingress and powerful water jets, making it suitable for outdoor installation in any climate.
• Wide Operating Temperature Range: Designed to perform reliably from -25°C to +60°C (or wider, configurable), accommodating diverse environmental conditions.
• Optimized Thermal Management: Internal layout and optional ventilation allow for efficient heat dissipation, preventing component degradation.

4. Optimized Performance & Reliability

• Low Resistance Components: Utilizes high-quality, low-resistance busbars and connectors to minimize power loss and ensure maximum energy transfer.
• Efficient String Aggregation: Flawless aggregation of multiple DC strings into a single, high-current output for seamless connection to the inverter.
• Long Lifespan: Engineered with industrial-grade components and meticulous assembly for a guaranteed operational lifespan of 25+ years.

5. Ease of Installation & Maintenance
