Panel mount solar connector 1500 V performance and ratings

The H4 PV Panel Connector is designed to carry more current than typical industry-standard PV panel connectors while maintaining low contact resistance and stable performance over decades of operation. Certified to UL 6703 and IEC 62852 standards, it supports high string voltages common in today’s utility-scale and commercial rooftop arrays. Current ratings span multiple conductor sizes, allowing system engineers to right-size conductors without sacrificing ampacity or safety margins.

A single power contact simplifies the DC path while maintaining robust creepage and clearance distances inside the housing. Tin-plated copper alloy contacts deliver consistent conductivity, and the proven H4 interface supports repeatable mating with compatible connectors in the Amphenol PV portfolio. This combination of high voltage rating, high current capability, and low power loss helps maximize energy harvest and system efficiency.

Rugged panel-mount construction for harsh environments

Outdoor PV installations demand interconnects that withstand UV exposure, temperature extremes, and moisture intrusion. This panel mount solar connector 1500 V uses a durable thermoplastic housing paired with silicone rubber sealing components to achieve IP68 protection when properly mated, along with IP2X touch-proof safety. The design is rated for an operating temperature range from -40 °C to +85 °C, supporting installations from cold climates to hot desert conditions without derating beyond published specifications.

The panel-mount form factor provides a secure mechanical interface to module junction boxes, combiner enclosures, or power conversion equipment. With an integrated locking element that meets NEC 690.33(C) requirements for tool-operated unmating, the connector resists accidental decoupling due to vibration, cable tension, or handling. Long-term UV and ozone resistance of the housing materials further supports extended service life in demanding outdoor environments.

Standards compliance and safety features built in

The panel mount solar connector 1500 V is dual approved to UL 6703 and TÜV-certified to IEC 62852, giving OEMs and system integrators a straightforward path to code-compliant PV designs. It meets NEC 2008/2011 requirements without additional locking collars or sleeves, reducing part count and simplifying the bill of materials. Touch-proof geometry and reverse-gender construction help minimize the risk of accidental contact with live parts during installation and maintenance.

These safety and compliance attributes make the H4 PV Panel Connector a strong choice for global projects where regulatory expectations and inspection practices vary by region. Using a connector that is already qualified to leading standards can shorten design cycles, streamline approvals, and support repeatable system designs across multiple projects and geographies.

Flexible options for panel and system designers

The panel mount solar connector 1500 V is available in multiple current and conductor size options to match a wide range of PV module and system architectures. Typical configurations cover conductor sizes from 2.5 mm² (AWG 14) up to 10.0 mm² (AWG 8), with corresponding current ratings that support both standard and high-power module outputs. Designers can select the appropriate gauge to balance voltage drop, cable cost, and mechanical flexibility.

Field-assembly capability enables installers or value-added partners to terminate connectors close to the point of use, supporting custom harness lengths and routing. Full mate-ability with Amphenol’s broader PV product line allows the panel connector to interface cleanly with cable-mounted H4 connectors, junction boxes, and other DC balance-of-system components. This portfolio approach helps standardize on a single interconnect family across modules, home-run cables, and combiner inputs.

Typical applications in modern solar installations

The panel mount solar connector 1500 V is suited for use wherever a sealed, touch-proof panel interface is required in PV systems. Common applications include utility-scale solar farms using high-voltage string or central inverters, commercial and industrial rooftop systems, and residential arrays designed for long service life with minimal maintenance. The connector’s rating and environmental robustness also make it appropriate for tracker-based systems, ground-mount arrays, and carport structures exposed to wind, dust, and precipitation.

Because the connector is panel-mounted, it provides a clean transition from the module or enclosure wall to external cabling, simplifying service and replacement. Installers can disconnect external leads while leaving the panel connector secured in place, supporting efficient maintenance practices and reducing the risk of damage to the enclosure or internal wiring.

Why choose the H4 PV Panel Connector

Selecting the right panel mount solar connector 1500 V solution is critical when reliability, safety, and long-term energy yield are priorities. The H4 PV Panel Connector combines high ampacity, proven H4 contact technology, and durable IP68-rated construction with comprehensive global certifications. Its panel-mount design, multiple gauge options, and compatibility with a broad PV connector ecosystem give OEMs, EPCs, and installers a flexible, system-level building block for DC power collection.

Backed by Amphenol Industrial Operations’ experience in alternative energy and harsh-environment interconnects, the H4 PV Panel Connector offers a dependable path to standardize PV panel and enclosure interfaces across projects and product lines.
