How Do You Select the Right Connector Model and Specifications?

Solar cell modules heavily rely on photovoltaic connectors, which are designed to function in challenging environmental conditions with significant temperature fluctuations. While the climate varies across different regions, and even within the same area, the environmental factors can significantly influence the materials and their resulting products. It’s crucial to consider these factors when selecting connectors for optimal performance in YORO NEW ENERGY solar systems.

In conclusion, when evaluating photovoltaic connectors for YORO NEW ENERGY solar systems, four primary environmental factors come into play:

1. Solar Radiation: The impact of solar radiation, particularly ultraviolet rays, on polymer materials like plastics and rubber is significant.
2. Temperature Fluctuations: Alternating high and low temperatures pose a rigorous challenge to both materials and the finished products.
3. Moisture and Pollutants: Factors such as rain, snow, condensation, acid rain, ozone, and other contaminants can adversely affect the material.
4. Electrical Safety and Durability: Beyond environmental factors, the connector must offer high electrical safety protection and have a lifespan exceeding 12 years.

Considering these factors ensures the longevity and efficiency of the connectors in diverse conditions.

The performance requirements of photovoltaic connectors are:
1) The structure is safe, reliable, and easy to use;
2) High resistance to environmental climate indicators;
3) High sealing requirements;
4) High electrical safety performance;
5) High reliability;

Key Environmental Considerations for YORO NEW ENERGY Photovoltaic Connectors:

Prioritizing safety is paramount in every facet of life, and this principle is especially crucial when considering the challenging environments where many electrical connectors operate. Adopting a “safety-first” approach necessitates meticulous attention to the customization of connectors.

Here are the pivotal environmental challenges that photovoltaic connectors might face:

1. Water Immersion: Connectors might be submerged, making it vital to ensure they remain functional even when underwater.
2. Exposure to Elements: Connectors can be exposed to water, chemicals, or other corrosive agents that might degrade their quality over time.
3. Temperature Extremes: The connectors should be resilient enough to withstand both scorching and freezing temperatures.
4. Fine Particles: Dust and tiny particles can infiltrate and damage connectors if they aren’t adequately sealed.
5. Abrasive Materials: Rough materials coming into contact with connectors can wear them out, affecting their efficiency.
6. Physical Stress: Connectors should be robust enough to handle bending and flexing without compromising their integrity.

Here are the pivotal environmental challenges that photovoltaic connectors might face:

✅Water Immersion: Connectors might be submerged, making it vital to ensure they remain functional even when underwater.
✅Exposure to Elements: Connectors can be exposed to water, chemicals, or other corrosive agents that might degrade their quality over time.
✅Temperature Extremes: The connectors should be resilient enough to withstand both scorching and freezing temperatures.

✅Physical Stress: Connectors should be robust enough to handle bending and flexing without compromising their integrity.
When selecting a connector for YORO NEW ENERGY systems, it’s advisable to opt for those with the highest IP (International Protection) ratings. An IP rating is denoted by two numbers. The first digit indicates protection against solid objects like dust, while the second digit signifies protection against water ingress. The higher the digits, the better the protection. For instance, an IP00 rating offers no protection, whereas an IP68 rating, considered top-tier, ensures complete dust protection and resistance against prolonged water immersion. Always aim for connectors with superior IP ratings to ensure longevity and optimal performance in diverse conditions.

Key Considerations for Selecting YORO NEW ENERGY Solar Connectors:

1. Shell Insulation Material: Given the challenging environments where photovoltaic connectors operate – from saline coastlines to desert plateaus, and from scorching equatorial regions to frigid latitudes – the durability of the shell insulation material is paramount. It must withstand solar radiation, precipitation, and abrasive elements like wind and sand. The material should possess excellent weather resistance, heat tolerance, flame retardancy, mechanical strength, and insulation properties. This ensures that both the inner copper core and the external insulation remain intact for a minimum of 25 years.
2. Sealing: The interior of a YORO NEW ENERGY solar connector houses the copper core of the plug-in and the cable. Given that these components lack anti-corrosion properties, it’s vital for the connector to isolate the copper core from external elements. When paired with an inverter (or controller), the connector’s sealing function must be impeccable to maintain the inverter’s integrity. During installation, it’s crucial to tighten the sealing screw to ensure optimal protection.
3. Contact Resistance: As per the latest international standard, IEC 62852, for photovoltaic connectors, the contact resistance should not exceed an increase of five mΩ after testing. Alternatively, the final resistance value should remain below 150% of the initial measurement. When utilizing top-tier YORO NEW ENERGY photovoltaic connectors, the energy consumed by the connector is negligible, accounting for less than 0.01% of the system’s total power. Conversely, subpar connectors can consume energy more than 30 times that of premium connectors. The primary cause of connector failures and potential fires is the escalating contact resistance, leading to excessive temperature rises that surpass the tolerable limits of the plastic shell and metal components. The contact resistance is predominantly influenced by the copper core’s material and dimensions. Different brands may have varying connector specifications, so it’s advisable to avoid mixing connectors from different manufacturers. During installation, ensure that the connectors are securely in place. Authentic YORO NEW ENERGY connectors will produce a distinct sound when correctly inserted.
