YePV IPC4116120 Solar Insulation Piercing Connector

Product Introduction

The YePV Brand-New Solar Insulation Piercing Connector is a premium no-strip solar tapping connector for photovoltaic power systems, featuring IP65 environmental protection and dual-voltage options: AC 1000V and DC 1500V. As a reliable solar IPC piercing connector, it delivers typical contact resistance ≤5 mΩ to cut power loss and maintain efficient energy transfer.

Constructed with durable PA/CU materials, this insulation piercing cable connector adopts optimized structural design for stable field performance. It supports broad cable specifications: tap connection for 2.5-16mm² (max OD 9.0 mm); main connection for 10-120mm², compatible with both copper and aluminum conductors. Wide cable compatibility simplifies on-site wiring and reduces spare-part inventory costs.

The piercing-type structure removes the need for cable insulation stripping and greatly speeds up installation work. With UV-resistant and IP65 waterproof performance, it sustains long-term service under tough outdoor conditions, lowering maintenance expenditure and improving whole-system reliability. YePV IPC provides a cost-effective, safe and efficient solar cable tapping solution.

Product Specifications

Built with high-grade PA/CU composite materials for excellent mechanical durability and electrical conductivity.

Typical contact resistance: ≤5 mΩ for low-loss power transmission

Tap connection cable range: 2.5-16mm², max outer diameter 9.0 mm

Main connection cable range: 10-120mm², fits aluminum and copper conductors

Core Features

This heavy-duty solar insulation piercing tap connector is a time-saving wiring component for PV projects. It reaches IP65 dust-tight grade and resists low-pressure water jets from all directions, well-suited for outdoor solar installations. Dual-voltage versions (AC 1000V / DC 1500V) cover diverse application scenarios, ranging from residential rooftop PV to large-scale utility solar farms.

Our Advantages

Dual-Voltage Compatibility: Supports 1500V DC and 1000V AC, adaptable for most solar power distribution applications.

Low Contact Resistance: ≤5 mΩ contact resistance guarantees efficient power transmission with minimal energy waste.

Tinned Copper Contact: Premium tinned copper insert brings high conductivity and anti-corrosion performance.

IP65 Environmental Protection: Dust-proof and jet-water resistant, stable for long-term outdoor deployment.

High-Torque Nut-Locking Structure: Locking force＞12 Nm, achieves firm cable clamping and prevents accidental loosening.

Application

YePV IPC4116120 solar insulation piercing connector is widely used as a PV cable branch tapping connector in photovoltaic systems for connecting solar panels, inverters and battery energy-storage units.

Thanks to its insulation-piercing working principle, there is no requirement for stripping cable insulation before installation, shortening construction time and reducing human-caused wiring faults. It works for both DC-side high-voltage solar array transmission and AC-side grid-tied connection. Rugged housing enables continuous operation under harsh outdoor climates for stable solar power generation and distribution.

Capacity & Safety Calculations

Under standard working conditions, one main cable can safely mount up to 6 IPC tapping units.

Take standard 4mm² (12 AWG) solar panel cable as reference:

Max theoretical loading: 4 cables × 4mm² × 6 units = 96mm²

When using 120mm² (4/0 AWG) main cable, the cross-section margin exceeds 96mm²; 95mm² (3/0 AWG) main cable cannot meet this requirement. Follow this rule for safe project design.

FAQ

Solar DC Insulation Piercing Connector — buyer questions

What makes YePV IPC4116120 solar insulation piercing connector different from ordinary connectors?

This solar IPC tap connector uses an insulation-piercing contact mechanism to skip wire-stripping work. It features IP65 outdoor protection, low contact resistance and multi-size cable compatibility, bringing better convenience and reliability for solar field tapping connections.

Can this piercing connector work with both aluminum and copper cables?

Yes. YePV IPC4116120 supports both aluminum conductors and copper conductors, giving more flexibility for different solar project cable schemes.

Is the insulation piercing connector easy to install?

Very user-friendly. The piercing contact design removes insulation-stripping steps and speeds up field wiring. Proper nut-torque operation ensures stable clamping and avoids loose-connection risks.

What voltage ratings are available for this solar piercing connector?

Two voltage options: AC 1000V and DC 1500V, to satisfy different DC PV array and AC grid-connected system requirements.

What practical benefits does IP65 rating bring?

IP65 grade achieves dust-tight performance and defense against low-pressure water jets. It protects internal contacts from outdoor dust and rain splash, extending service life for solar on-site installations.
