Technical Data

Core Function

key support to ensure stable operation of photovoltaic systems

Electrical connection function: the basis for efficient transmission of electrical energy

The MC4 connector utilizes precision-machined metal contacts, achieving a low-resistance connection through optimized contact structure and material selection. This design not only reduces power loss during transmission, ensuring maximum utilization of the power generated by the photovoltaic system, but also avoids localized heating caused by excessive contact resistance, laying the foundation for safe system operation. It is the core of the connector's power transmission capabilities.

Safety locking mechanism: an important safeguard against unexpected risks

The connector has an integrated locking clip that automatically engages and locks the connector when the plug and socket are mated, creating a secure connection. This automatic locking design, requiring no additional operation, prevents accidental disconnection during routine maintenance, minor external collisions, or environmental influences, thus avoiding system downtime losses caused by sudden power outages. It also reduces safety hazards caused by human error, providing reliable safety protection for the continued operation of the photovoltaic system.

Environmental protection capability: a key barrier to adapting to complex environments

When the MC4 connector is mated, its sealing structure can achieve high-level protection standards such as IP65, IP67, and IP68. IP65 completely blocks dust intrusion, while IP67 and IP68 prevent moisture penetration at varying water depths and durations. This powerful protection effectively withstands the harsh outdoor environments common in photovoltaic systems, including dust, rain, dew, and even salt spray in coastal areas and low temperatures at high altitudes. It protects the connector's internal components from damage and ensures stable performance in a variety of complex environments.

Diverse configurations: Flexible solutions to meet different wiring needs

The MC4 system is not a single plug and socket combination, but covers a wide range of product types. In addition to the basic plugs and sockets, it also includes branch connectors, test plugs, device connectors and other variants. Branch connectors can realize parallel or series wiring of multiple photovoltaic modules, meeting the complex circuit layout requirements of large systems; test plugs facilitate operation and maintenance personnel to perform parameter detection without interrupting system operation; device connectors can adapt to the interfaces of different photovoltaic equipment such as inverters and combiner boxes. This diversified configuration allows the MC4 connector to flexibly respond to wiring needs in different scenarios such as residential rooftops, large power stations, and commercial buildings, without the need for additional customized adapter components, greatly improving the convenience of photovoltaic system installation and expansion.

Product Features

To better utilize its core functions, the MC4 connector has matching product features: it supports a maximum DC 1500V rated voltage to meet the needs of large power stations; its housing is made of impact-resistant material that is UV-resistant, corrosion-resistant, and adaptable to a wide temperature range; its advanced connection technology ensures long-term low contact resistance; and it offers crimping and tool-free installation options for simplified operation. These features provide strong support for the stable performance of its core functions.

Application areas

Actual scenario implementation of core functions

With its powerful core functions, the MC4 connector is widely used in large-scale ground power plants (deserts, high-altitude environments), distributed photovoltaic systems (commercial, industrial, and residential rooftops), special environments (coastal saline-alkali land), building-integrated photovoltaics (BIPV), and emerging fields such as solar carports and charging stations. Its core functions can ensure stable system operation in various scenarios.
