Photovoltaic (Solar Panel) Connectors

As a type of photovoltaic (PV) power supply, photovoltaic (solar panel) connectors have become widely used in the recent years. The high-efficiency solar cells and efficient PV modules require efficient connections to enable their successful operation. There are various types of solar panel connectors available on the market, including H4CMN2DM for residential, commercial, and industrial photovoltaic systems. This article will focus on the application field and working principle of H4CMN2DM.

Application Field

H4CMN2DM connectors are designed for residential, commercial, and industrial photovoltaic systems in high-power applications. They are suitable for a wide variety of systems, including rooftop systems, solar parks, and large-scale projects. H4CMN2DM connectors have an extra layer of protection between the contacts by using an insulation material, thus protecting against water and dust. In addition, the connectors are able to handle currents up to 20A and a voltage rating of up to 600V DC, while ensuring the highest efficiency and reliability.

Working Principle

H4CMN2DM connectors are based on the ‘push and pull’ principle, which enables the easy installation and safe operation of the connectors. Both the male and female parts of the connectors are equipped with notches that allow for an easier mounting of the connectors on the panels. The entire assembly consists of a housing, contact pins, and locking ribbons that are designed to provide reliable connections between the conductors in the panel. The housing also provides a secure mechanical attachment between the contact pins and locking ribbons, preventing accidental disconnection or mechanical wear and tear due to vibration.

The contact pins are made of silver-plated brass material and have an insulation material at the base of the contact pin. This insulation material ensures that the voltage is constantly maintained even in the presence of humidity or harsh climate conditions. In addition, the contact pins have a tapered design to ensure that the connection is secure and reliable even in the presence of current and voltage variations.

The ribbons on the H4CMN2DM connectors are made from Nickel-plated copper material and are designed to be corrosion-resistant. The ribbons are arranged in a unique overlapping fashion to provide a secure connection between the contact pins and the panel, and to prevent accidental disconnection. The locking ribbons also feature spring-loaded plungers that allow them to expand when connected to the panel, thus providing a tighter fit and an extra layer of protection against corrosion.

In addition, H4CMN2DM connectors are also designed with safety features such as over-current and over-voltage protection. This feature helps to protect the system from over-voltage or current sensing by monitoring the current and voltage and disconnecting the circuits if these values are exceeded. Additionally, the connectors feature an LED indicator light, which helps to indicate the status of the connection and prevents accidental disconnection.

H4CMN2DM connectors are an efficient and reliable solution for PV systems in high-power applications. The connectors are designed for secure and reliable connections, while ensuring that the current and voltage are maintained even in the presence of weather and other environmental factors. These features make them an ideal choice for a wide range of photovoltaic applications.
