DC 1500V Solar PV Inline Fuse Connector Extension Harness (Cable Jumper with Fuse)
Solar Extension Cable Fuse Connector
MC-Compatible Male and Female Connectors
IP68 Waterproof
Customized upon request
Product Introduction
Save Installation Time. Protect Every PV String. Built for 1500V Solar Systems.
Modern photovoltaic (PV) systems require more than reliable electrical connections—they demand fast installation, effective overcurrent protection, and long-term outdoor durability.
NSPV 1500V PV Inline Fuse Connector Harness, also known as a Cable Jumper with Fuse Connector, is an integrated pre-assembled cable solution that combines a PV extension cable with a DC inline fuse connector. It enables installers to complete both cable connection and string protection in one step, significantly reducing field wiring time while providing overcurrent protection through a correctly selected PV fuse.
Designed for residential, commercial, utility-scale solar farms, and energy storage systems (ESS), This solution is designed for 1500V DC photovoltaic applications, subject to the applicable component ratings and system requirements. and is available with TÜV and ETL certifications, ensuring reliable performance in global solar projects.

Why Choose NSPV PV Inline Fuse Harness?
Faster Installation, Lower Labor Cost
Traditional installations require separate extension cables, fuse connectors, and additional assembly on-site.
The NSPV Cable Jumper with Fuse is factory-assembled and tested before delivery, allowing installers to simply plug and play.
Benefits include:
- Pre-assembled factory wiring
- No field crimping required
- Reduced installation time
- Lower labor costs
- Fewer installation mistakes
- Consistent connection quality
For EPC contractors and solar installers managing hundreds or thousands of PV strings, these time savings translate directly into lower project costs.
Complete Overcurrent Protection
Every photovoltaic string should be protected against overload and reverse current.
The integrated PV fuse is designed to interrupt excessive current within its specified operating characteristics, helping protect the affected circuit against overcurrent-related damage. Correct fuse selection must consider system voltage, expected fault current, cable ampacity, module specifications, and applicable installation requirements.
Typical Installation Configuration
The inline fuse is installed in the conductor or conductors specified by the PV system design. Fuse placement and ratings must be selected according to the system grounding arrangement, module specifications, expected reverse current, and applicable electrical codes. A standard cable jumper without a fuse may be used on the other conductor where permitted by the design and applicable requirements.
This configuration is widely adopted because it:
- Meets PV string overcurrent protection requirements
- Reduces component costs
- Simplifies system design
- Maintains high installation efficiency
The result is an optimized balance between electrical protection and project cost.
Designed for Modern 1500V Solar Systems
The NSPV Inline Fuse Harness is suitable for:
- Utility-scale solar power plants
- Commercial rooftop PV
- Residential solar installations
- Floating solar systems
- Agrivoltaic projects
- Battery Energy Storage Systems (ESS)
- PV combiner boxes
- String inverter systems
- Central inverter systems
Compatible with industry-standard PV connectors, it is designed for outdoor PV applications under the specified environmental conditions.
