Product Features

High Current Capacity with Low Contact Resistance

The connector utilizes precision-machined copper alloy contacts with high-conductivity plating to ensure efficient power transmission. Low contact resistance minimizes energy loss and heat generation, helping improve the overall efficiency of photovoltaic systems while supporting continuous operation under high current loads.

1500V DC High Voltage Design

Designed for next-generation photovoltaic installations, the connector supports systems up to 1500V DC, making it suitable for large commercial rooftops, solar farms, battery energy storage projects, and utility-scale renewable energy applications. The enhanced voltage rating contributes to longer string configurations and improved system design flexibility.

IP67 Waterproof and Dustproof Protection

Multiple sealing rings and precision housing design provide excellent protection against moisture, dust, and environmental contaminants. The IP67 protection level allows the connector to maintain stable electrical performance even in harsh outdoor environments exposed to heavy rainfall, sand, humidity, or snow.

Excellent Weather Resistance

Constructed from UV-resistant PPO or PA engineering material, the housing resists aging, corrosion, and long-term ultraviolet exposure. The connector remains mechanically stable across a wide operating temperature range, making it suitable for installations in deserts, coastal regions, tropical climates, and cold environments.

Secure Locking Mechanism

The integrated locking structure provides a reliable connection that resists vibration and accidental disconnection. During installation, connectors can be quickly assembled without complicated procedures, reducing labor time while maintaining a secure electrical connection.

Compatible with Standard PV Cables

The connector is designed for use with common photovoltaic cables and supports several conductor sizes, making it suitable for new installations as well as system upgrades. Factory customization is also available for different cable diameters, branding, and packaging requirements.

Factory Quality Assurance

Every connector is manufactured using precision injection molding and automated assembly equipment. Finished products undergo strict inspection procedures, including contact resistance testing, insulation testing, waterproof verification, insertion and withdrawal force testing, and visual inspection to ensure consistent product quality.

Product Specifications

The 30A 1500V PV connector is suitable for virtually all photovoltaic power generation systems that require reliable DC cable connections. It is commonly installed in residential rooftop solar arrays, where long-term outdoor durability and safe electrical performance are essential. Commercial rooftop photovoltaic systems also benefit from its low-resistance contact design and weatherproof construction, helping maintain stable power generation over extended operating periods.
