After nuclear sewage, I can hear the voices of plants

For this solar panel, Lu Linlin has been learning about mechanics and circuits since she came back. Fortunately, Jiang Yan has a variety of books at home, otherwise she would not know how to repair this solar charging panel.

Giving up his position, Jiang Yan signaled Lu Linlin to start, squatting next to the solar charging panel, and Lu Linlin turned the entire panel over, revealing the circuit structure on the back.

"This has a waterproof function. If the outer shell is not damaged, it can work normally."

After carefully checking the casing of the solar charging panel to ensure that there were no cracks or damage, Lu Linlin explained to Jiang Yan, who was also squatting next to her.

"But something seems to be missing."

Looking at the solar charging panel, Lu Linlin recalled the content in the book and kept looking for something on the back of the solar panel.

"What is missing?"

Jiang Yan on the side heard this and spoke hurriedly. Such an important thing made Jiang Yan very nervous now.

"There should be a voltage converter missing. The current released by the solar charging panel is not stable, so a voltage converter is needed to stabilize the current. But currently there are only boards and batteries, and I don't see anything that looks like a voltage converter." Put it down. Solar panels, Lu Linlin kept looking for things similar to voltage converters around.

Hearing this, Jiang Yan was confused and didn't know what the voltage converter Lu Linlin was talking about was. After scratching his head, Jiang Yan asked.

“What should that thing look like?”

"It might be a larger plug, or it might be a box." After searching around, Lu Linlin drew a rough shape with her hands.

Hearing this, Jiang Yan kept searching the memories in his mind. When he brought the solar charging panel back, it seemed to be accompanied by a square box. But at the time, Jiang Yan thought this thing was from a battery car, so he didn't think anything of it. Pay attention.

"wait for me a while."

Recalling the memories in her mind, Jiang Yan returned to the farmhouse. After a jingling sound, Jiang Yan walked out carrying a box.

"Is this it?"

Placing the metal box in front of Lu Linlin, Jiang Yan rubbed her arms.

Moving the metal box in front of her, Lu Linlin recognized the words on it and nodded excitedly.

With the transformer, solar panel and battery, the next operation becomes simple. You only need to connect all three, and a simple solar charging panel is completed.

Holding the copper wire, Lu Linlin cut the plug of the solar panel to short, then tore off the outer covering of the wire, connected it with her own copper wire, and then wrapped it tightly with waterproof black tape.

"Sister Yan, where is this solar charging panel?"

After connecting the circuit, Lu Linlin raised her head and asked Jiang Yan. After hearing this, Jiang Yan stood up and looked at the entire yard, and then set her sights on the roof of her house.

If the solar charging panel is placed on the roof, the lighting efficiency will be much higher than on the ground. Moreover, because it is on the roof, Zhao Dabai and Kaka will not damage it when playing around. There is also the wiring. It will be easier.

Seeing Jiang Yan's gaze, Lu Linlin stood up and her eyes gradually glowed as she looked towards the roof.

"Rooftop!"

The two hit it off immediately. Lu Linlin held the ladder, and Jiang Yan carried the solar charging panel to the roof. Along the gap that had been repaired on the roof, Jiang Yan used a claw hammer to lift off the edge of the wooden strips, and then along the side. Slow down the line bit by bit.

After finishing these tasks, Jiang Yan picked up two more hollow bricks from the ground, used them as brackets for solar panels, and then began to repair the roof that had just been pried open.Seeing this, Lu Linlin on the ground returned to the house, took the wire that Jiang Yan had brought down, took out the copper wire and extended it partially, and then connected the other end to the transformer. The method of connecting the electricity was not as expected. The difficulty was only because Jiang Yan didn't have any knowledge in this area and seemed ignorant.

Taking out the tape and gluing the connection, Lu Linlin took out the car battery cable placed outside, connected it to the transformer, and stuck the other end on the positive and negative terminals of the battery.

The knocking on the roof woke up Lu Lili, who was still sleeping. She walked out of the room with her clothes on. Lu Lili looked at her sister's busy figure in the living room, and her brain couldn't turn around for a while.

"what to do?"

Hearing her sister's voice, Lu Linlin raised her head and said excitedly: "We will have electricity in the future!"

"what is that?"

However, Lu Lili, who had never read a book, had no idea what household appliances were. Seeing her sister's excitement, Lu Lili rubbed her eyes and raised her head to look at the ceiling.

"What are Sister Yan doing? Has the house collapsed?"

"No, you go wash your face."

Looking at Lu Lili's stunned figure, Lu Linlin's enthusiastic surprise gradually calmed down. After checking whether the battery was charged, she waved her hand and drove Lu Lili away.

Coming down from the roof, Jiang Yan put the tools he carried into the storage room, then walked to Lu Linlin's side, bending down to observe the two people's masterpieces.

The two car batteries at home are finally able to exert their capabilities. Counting the battery in the battery car, Jiang Yan already has three car batteries at home, which are enough for her own lighting.

"How's it going? Is it useful?" Jiang Yan asked Lu Linlin excitedly after wiping the indicator light on the battery and seeing the indicator light on.

"Useful, very useful." Lu Linlin said excitedly while observing the various characters on the battery.

"How long does it take to charge this battery?"

After hearing Jiang Yan's question, Lu Linlin glanced at the information mark on the battery and then stood up.

"This battery is 1200W, and this solar charging panel is..."

"No need to say this, I don't understand, just tell me how long it will take."

Seeing Jiang Yan's refusal, Lu Linlin said helplessly: "In the fastest case, these two batteries will each take 12 hours to be fully charged, and the battery of the battery car will last longer, taking 23 hours."

Hearing this, Jiang Yan looked at the battery of the electric car in shock. The battery of this small electric car was actually larger than the two car batteries.

"But this solar charging panel depends on the weather. If there are many clouds, it will take longer. If it is cloudy and rainy, this solar charging panel will have no effect."

Walking outside the door, Lu Linlin looked at the sky and faced Jiang Yanjiang's street.

Following Lu Linlin out of the door, Jiang Yan looked at the sky where the clouds were gradually gathering, and the raised corners of his mouth suddenly sank.

"Is it going to rain?"
