Causes of burnt out solar photovoltaic connector
Solar photovoltaic connector may burn due to the following reasons：
【overcurrent】
Overload current is one of the most common causes of connector burnout in photovoltaic systems. When the current in the system exceeds the rated current capacity of the connector, the connector may not be able to withstand overload, leading to overheating and eventually burning out. This can be due to poor system design, failure, partial shading, or other problems.
【Poor or unstable contact】
Poor or unstable connector contact can lead to high resistance and resistance heating. This can be caused by connectors that are not properly installed, loose, falling off, corroded, oxidized, or damaged. Poor contact will increase resistance, cause local heating, and eventually trigger connector burnout.
【short circuit】
A short circuit inside the connector is another common cause of connector burn. Short circuits may result from direct contact between the wires, or accidental contact between the wires and the metal housing or other conductors. A short circuit can cause a large current to flow through the connector, causing overheating and burning.
【Material aged or damaged】
Materials used in connectors may undergo aging or damage over time. This can be caused by long-term exposure to harsh environments such as high temperature, UV radiation, humidity, chemicals, etc., or due to mechanical stress or other external forces.

To prevent connector burning, the following measures can be taken:
【Select the appropriate connector】
Ensure that the rated current capacity of the connector matches the design requirements of the system to avoid overload.
【correct installation】
Install connectors correctly according to the manufacturer's installation guide and recommendations to ensure good contact and stability.
【Regular inspection and maintenance】
Check the status of connectors regularly, including loosening, damage, corrosion, etc. Clean, tighten or replace damaged connector parts in a timely manner.
【safeguard procedures】
Protective measures such as the use of waterproof enclosures, sealants, etc. are taken to protect the connectors from humidity, moisture, and chemicals.
【load management】
Ensure that the current and power in the system do not exceed the rated capacity of the connector and avoid overload situations.
