After I released the clip of high-voltage solar cells for inverter air conditioners, it received a lot of attention. I thought that solar cells could be connected directly to the hot coils of the air conditioner. In fact, it is not possible. You have to insert the bridge diodes backwards before you can use the solar cells. It is a continuation of the previous clip that Professor Kai explained the method and revealed the technique, but new people may not have seen it. Today, I asked Professor Kai to explain again, clearly about the method of converting the hot coils of the air conditioner to use with solar cells. There are hot coils of 2 brands of air conditioners to show. But I would like to warn again that not all brands of inverter air conditioners can be used. Some brands used to be able to use them, but the new hot coil boards do not support solar cells. The latest one we found is the new Heier brand. It can no longer be used. I don't know about other brands. I am still testing them.
