Key Technical Details of Solar Distribution Box

Although the solar distribution box looks inconspicuous, it has a lot of technical skills. Today, I will break it down and talk about these key technical details.

First of all, we have to talk about the fast power-off technology. Ordinary fuses react slowly, and the daylily is cold by the time it melts. The current solar distribution box uses electronic fusing technology, which can cut off the circuit within one millionth of a second when encountering a problem, which is faster than blinking an eye. Tesla uses this technology, which can effectively prevent battery over-discharge or fire.

Let's talk about the monitoring system. Today's solar distribution box is very smart. It is equipped with various sensors that can monitor current, voltage and temperature 24 hours a day. Temperature exceeds 85 degrees? Abnormal current? It can immediately alarm and transmit data to the mobile phone. The operation and maintenance personnel can know which board has a problem while sitting in the office.

The material is also very particular. The shell is not made of ordinary plastic, but a special engineering plastic that can withstand temperatures from minus 40 degrees to 125 degrees, and it is not a problem to use it for 25 years. It is also very waterproof and dustproof, and can be used in places such as deserts and seaside.

Safety protection is of utmost importance. The lightning protection uses advanced varistors that can withstand 20,000 amperes of surge current. There is also an arc protection function, which can immediately cut off the wires if they are found to have poor contact to prevent fire. Some high-end products also have a design to prevent rat bites, which is very thoughtful.

However, there is still a problem that has not been completely solved, that is, how to ensure sealing while dissipating heat well. Especially in high-temperature areas, this problem is more obvious.
