Importance and selection of protective door lock for photovoltaic inverter

In the photovoltaic power generation system, the inverter is an important device to convert the direct current generated by solar cells into alternating current, and the protective door is one of the key devices to protect the inverter from external factors. As the "goalkeeper" of the protective door, the door lock of the photovoltaic inverter protective door is a link that cannot be ignored.

1, the role of photovoltaic inverter protection door lock

Protection door lock of photovoltaic inverterIt mainly plays two roles: one is to prevent non-professionals from opening the inverter box at will; The second is to avoid damage to the inverter caused by natural environmental factors (such as rain and dust). A good door lock can not only ensure the safe operation of the inverter, but also effectively extend its service life.

2, photovoltaic inverter protection door lock selection criteria

① Excellent material: The door lock made of high-quality material can better resist bad weather conditions and external shocks, and has strong corrosion resistance.

② Structural stability: A good door lock should have a firm and stable structural design, which is not easy to be damaged or pried open.

③ Easy operation: Convenient and quick opening and closing function is very important for maintenance personnel, which can improve work efficiency.

④ Good waterproof and dustproof performance: especially when it is installed and used outdoors, it needs to have certain waterproof grade requirements and good sealing performance to effectively isolate moisture from entering the box and affect the working effect of internal electrical components.

3. How to properly maintain the protective door lock of photovoltaic inverter?

Regularly check and clean the impurities on the surface of the door lock;

Timely replacement of parts with serious aging and wear, such as spring leaf, screw and other parts;

Pay attention to heat preservation measures in winter to avoid freezing and blocking, which will lead to abnormal switching;

In case of special circumstances, maintenance should be carried out immediately to ensure normal use.

4. Summary

With the rapid development of China's new energy industry, "green energy" has become a hot topic of social concern, and more attention should be paid to safety issues in the process of building distributed photovoltaic power plants. Therefore, it is particularly important to reasonably purchase qualified and reliable photovoltaic inverter protection door locks! I hope the above contents can help you to understand this field more deeply.
