PV-30A PV-45A 1000V Solar DC Connector

The PV-30 MC4 Connector is a widely used electrical connector in photovoltaic systems, primarily for connecting solar panels and other components. Here is some basic information about the MC4 Connector:

1. Definition and Origin:
   - The MC4 connector is an electrical connector used in photovoltaic (PV) systems to connect solar panels and other components.
2. Features and Functions:
   - The MC4 connector consists of a cable end and a panel end, with the term MC4 typically referring to the cable end.
   - It offers quick, reliable connections and is known for being waterproof, dustproof, and easy to use.
   - The MC4 connector housing is made of high-strength, anti-aging, and UV-resistant materials, effectively resisting harsh environments to ensure long-term stable operation of the system.
   - It features a male-female engagement mode, with the male and female plug design making installation more convenient.
   - It has characteristics such as structural design, self-locking mechanism, waterproof and dustproof properties, and flame retardancy.

3. Applications:
   - MC4 connectors are widely used in solar photovoltaic power generation systems, mainly for the series and parallel connections of solar panels.
   - They can also be used for cable connections to ensure efficient power transmission, with compression and clamping rings for reliability.
   - In system expansion and upgrades, MC4 connectors can easily connect new panels with existing systems, enhancing overall performance.

4. Design:
   - The MC4 connector features a two-piece design, including a male and a female end. The male end has an exposed contact point in the middle, and the female end has a socket that accepts the male contact point.
   - When connected, it provides a single contact between solar panels and cables or any other electrical components.
   - The single-contact design allows for quick coupling and decoupling while handling high currents.

5. Environmental Adaptability:
   - The MC4 connector is designed for outdoor use and can withstand harsh environmental conditions. It meets the IP67 rating, meaning it can prevent dust intrusion and can be submerged in water up to 1 meter deep for 30 minutes without damage.
   - The connector and its factory-crimped contacts are suitable for high-voltage direct current up to 1000V and can operate in a temperature range of -40 to 85°C.

The MC4 connector has become the standard connector in the solar industry due to its quick connection, waterproof performance, and durability, suitable for various solar energy applications from small consumer systems to large utility-scale installations.
