Hey guys, how are you, welcome, another video from the professor pardal Brazil channel, my friends in this video today and before we start I want to tell you something very serious Guys, this video has no tricks, it's all the information that I brought it to you , it's true for you, especially my friends, for you who want to save energy, okay, I can guarantee you that at the end of this video, we'll be turning on this refrigerator without spending even R$1 on the electricity grid outside, we'll be running this refrigerator with its own energy Okay, this battery here my friends, this battery is just a detail, everything that comes in this video is very important, this battery is just a detail Okay, so let's go, let's go to the next step and I'll show it to you, my friends, ok the refrigerator It is 110 Volts alternating current and the personal battery is 12 volts direct current it is very different both the attention and the wave model here there is no wave that is direct current so I can try to connect this refrigerator here to this battery anyway it won't work it wasn't made for that ok so it's as if the refrigerator spoke a language it spoke English and it's as if the battery spoke Portuguese we need to get a translator for one and start understanding the other Ok so for that my friends what the hell we're going to do this, I bought an inverter, this device here, my friends, it does this conversion, it takes either 12 volts or 24 volts or 36, you'll choose the model of the device from 220 to 110. And there are also different models like this one, but then I'll Leave the link, ok, there's a small one to connect light things, and there's also a bigger one, a bigger one, this one with 4,000 watts, okay, this one works like that, much bigger, a refrigerator, a sander, various types of machines, a washing machine, and so on, this is a I paid for the canopi inverter on today's date of the video, it's R$ 500. I'll leave the link there to prove it to you, ok, the price varies mainly there, but sometimes you can't get it later, even for a lower price.
Ok, so we're going to use this inverter, let's connect it to this battery and then we're going to run this refrigerator, set up a system that you'll see, we're going to spend neither R$ 1 nor 1 kg, right, from the utility grid Ok, so let's go, this refrigerator my friends, you have to remember that it was a more or less refrigerator around 80 to 100 watts, just these small refrigerators here, they consume little, so this small motorcycle battery will be able to start it, okay, but if it's a bigger refrigerator, a duplex refrigerator, right ? I'm going to do it, I'm going to connect them here now, we can't, guys, be careful, we can't turn on the inverter and invert the polarity, otherwise it will burn a direct current device. If you invert the polarity, it was already alternating current, there's no problem .
one way on the pin but when running the wall corresponds they have the right position you can't invert so red positive on red so on Ok so I'll call it and we'll be right back connecting the refrigerator So guys, inverter connected to the battery is the same as I already told you tighten the tight terminal on this battery, my friends, the motorcycle battery is only 5 amps, the small battery is 5 amps, so we're going to plug this one in because otherwise it won't work, we're going to plug it in here, come closer, go, come from this side, Please, guys, from the moment here, as I show you here, from the moment on, guys, I'm turning it on here, the refrigerator is about to start. Probably the inverter will scream because the battery current is low, but it will still start and the motor It's going to call Look and see for you, one two three and the refrigerator is working, guys, without any tricks Ok, everything here guys, today this information is very serious, there are no tricks, everything is true information, okay, because this is very serious and people need to save energy, the refrigerator is working Show here the engine running, guys, come down, Rafael, I'll put the microphone on so you can hear Ok, so guys, the fridge is already working. Let's show it here , and the light has already turned on, the sound of the gas circulating inside, it's already started to freeze, Ok, it's already started to freeze, so that's good.
So guys, I've already set up a multimeter here for you, here I put it negative and positive so you can see that the battery is already discharging 12. 8 12. 7 show it here Rafa Show it Ok then guys And now you can tell me So Joel you charge the battery how are you going to do it you will need electricity correct That's right, my friends, for this we've already done something, look here for you to see, we're already here with this wire in our hands, to show you there's an electric current, okay, it gives a shock, it's 40 volts, it's still not good, it can give a very light shock, but no it's not harmful Let's show here guys where this wire is coming from I already set up a solar panel up there guys and it's coming straight from there it's a 550 W solar panel this extension cord, show it here guys there, the extension cord is coming straight From there, my friends, a solar panel like this used to cost a lot, like R$ 2,000, a really expensive panel and today I bought a panel, then I'll give you the link, 750, I bought each panel like this and I'll show it to you too That one is the same, it's a solar panel, my friends, it lasts a long time and many years after 30 years, they already come with a 10 or 15 year warranty, just to give you an idea, that's why many companies are putting up solar panels, they 're not stupid guys, they're going count things that will last so you can put this in, it will only be assembled once in your house, ok so here we are an electrical competitor, the refrigerator has already turned off because the current has dropped too much, ok we are already at 12.
2, I tried to start it here, I didn't want to because it dropped too much battery current and if it passes on this side, guys And if I try to turn on this current, this electrical energy that is coming here directly to the battery, it will charge the battery, it will charge the battery, you can observe it with the multimeter. which is going to go up, look at the maximum film here now but the maximum that the battery can reach at personal voltage is 14. 5 14.
7 around 14:30 these lead batteries are ideal So how am I going to do it if I'm turning it on? the battery will pass the current, it will damage the battery, it may even burst, correct, so for this, for us to regulate this energy and connect the battery, we will use another device, ok, and with this device, we will automate this entire system here . and this refrigerator will work all day all day for free and we will be able to connect several other things, not just the refrigerator you will see that many other things Ok so let's leave this thread here guys I will show you that a solar panel is just one panel can even work a drill, this drill is 110 Volts, if there were two panels, this drill could work at full power than direct current, it is a little stronger, it delivers more due to the fact that it is continuous So here it is guys, just like I showed for you, I can even touch that you are not in shock, the electric current coming, okay, I'll show you, if I turn the drill on, I'll turn it on here, it even works.
Look, just the current, electric energy coming straight from the panel, you can even drill a hole. What if If I had two countries connected in series, this drill would work like a charm, many things don't even need to go through a converter, none of them work directly, few people know about this, so guys, this part controls the power coming from the panel and the battery will keep the battery always charged and it also has other functions that you will understand that will keep the refrigerator running and not let it damage the battery because this battery discharges a lot and it also damages it. So this part does the control and will also protect the battery It could be this one or it could be this one too, this one is cheap, you can buy it from R$ 100, you can get it, it's the famous blue one, the famous blue controller, Ok, this one is the mpppt, it costs around R$ 500 reais, but this one can do it deliver about 70% of the panel's power and this one already delivers about 90%, this one is much more efficient, so if the person This is Paul Mr it looks like that's the name and this is the little blue one, but the person is able to start with one one of these is better , but if you don't have one, this one also works very well, ok, but I've already prepared this one because it's more efficient to show you how it works, then we can connect this one too, since this one The controller will make the interface between the socket that is coming to the panel and the battery to keep it charged and the refrigerator running all the time, right?
Or at least when the battery runs out, everything will stop so as not to damage the battery. I have already prepared a socket, this socket. I'm going to connect it to the panel and this other one will come to the charger, always watching, always watching that you can't reverse polarity, okay guys, direct current if it reverses, it's gone, so black, I had already prepared the positive input in my socket, which is yellow, I've already painted it.
in red too so there's no mistake here, so I'm going to call here guys, look, film here close by, then here, in black here, look, I'm going to call here guys, it's a trick But it's just to show you, OK, if someone is going to put it together, they have to do it something better done to make it look cool There's also more security, the first thing is to connect a controller, we have to connect a controller to the battery for it to recognize the battery, then we can connect it to the panel Okay, so here's the input for the battery. It's even written Ó BT plus and BT - which is the positive and O negative and now I'm going to turn it on, I can't reverse it, it's already marked, I'm going to turn it on and it will light up ok but it's not charging yet, I'll show it to you, oh oh the battery is 12. 3 12.
2 and it's still not charging, right ? wrong here I almost burned my controller ok And here I also have red coming from the panel ok so we go to the place it shows here ok it's 12. 3 from the moment place now you will see that it will start charging ok Then, when you come back , the amperage has gone up here too guys, it shows the amperage, it shows it close up, it's getting a reflection, so Oh, this guy is showing the amperage that's coming in and here is the voltage, OK, it's showing that our battery is charging So guys, look at the battery Charging the battery, it didn't even have a charge anymore, I couldn't start the refrigerator but let's see if it will start now, it's already started, I'll show you here, I'll show you, the compressor is already working again, which is the filter connected here, show here an inverter is coming, look here, coming to the inverter, which is connected to the battery, which is connected to the personal solar system, so we already have a panel charging the controller, charging the battery, the battery supplying energy to the inverter and the refrigerator is connected, so it's here We can keep this refrigerator running all day long, it doesn't matter.
It may be sunny or there may be clouds in the sky because this panel is very large. Its proportion to the refrigerator is very large. for the refrigerator to work but what will happen is that it will arrive at night and the battery will discharge, correct if the battery discharges, it will ruin it, it cannot discharge, there is a minimum voltage, these lead batteries, in general, the ideal voltage for you to let them discharge is up to 12.
2, you shouldn't pass this load down. So we're going to automate this now and everything is very simple to automate because this device already comes with an output to automate the inverter, it's called load output, we just need to connect a positive wire here and the negative no load connect to a relay connect to the relay and this relay we will open There connect there it will turn off and turn on when the battery is discharged or charged the battery has charged it identified turns on the inverter the refrigerator turns on the battery discharged it identifies the battery It is discharged it also turns off the inverter, we automate this very simple one, every controller has the load output to automate the inverter, which is this little lamp output here, and here it also has this load output, we configure it, you can configure it for several types of battery if you want it to turn off with 12. 5 you want it to turn off only with 12 volts if you want it to turn on only when the battery is fully charged it is configurable with this we can now automate this battery here it doesn't even need to be a big battery new could be a used large car battery like I have Then I'll show you, ok, so we're going to automate it now, guys, something happened that's interesting, you notice that it's cloudy now, you notice it's not sunny, show the sign to everyone, so at this moment, show the sky, right now, here, right now It's cloudy at the moment and I'm going to show you that even so it's still working o Let's mark here to move on to charging the battery 12.
6 12. 7 and it's still delivering 12 amps look at how much it's charging o 13. 1 the battery charge So guys, even when it's cloudy it still works because the system, the board provides a lot of energy Ok, it will be possible to connect a lot of things, a lot of things besides a refrigerator, so here is the load output, which is what we are going to automate there, it is generally the output on the right but it can vary every time the battery the load output is charged, it provides energy to us, that's what Turns on this lamp, we're going to show it to you, every time, guys, like this, every time the light is on, it's because the load output is active and it indicates that the battery is charged, so if the battery is charged, 12 V is coming out here to get out of the way.
This is what this 12 volts are for, we will use it to connect a relay and this relay will perform the function and this personal relay we will connect two wires to this button here it will perform the function of turning the inverter on and off, it will be like our finger, the battery is discharged, we come here and disconnect the battery, it is charged, it identifies it, comes here and turns it on, we will connect a relay to do this service, okay. so I'm going to do it now, we're going to open it here, I'm going to have to turn off the system, we're going to open it and connect it to this little relay button and also connect it to the far exit, ok guys, I have a relay here, I bought it at auto electrical car it is a four-pin relay, it was R$ 15, this relay I bought there, so here it shows us, output 85 and 86 is what we are going to connect there to the load output, okay And here above the switch Turn off and turn off will do that function is the 30 and the 87 so the 85 and 86 we will connect to the load output and here it is already marked there are the numbers back here So we will solder the legs we will connect there and we will connect there Ok I'm going to weld it and we'll be right back, I've already made the connection here at the relief, I'm going to show you how I did it to connect it here to the inverter, the wire is already going in here but it's coming back here to both of us on the button, okay, it's ready to be removed. I didn't even need to open the lid.
I just stuck the knife here and the button has already come out, so one of the wires will be connected to one side of the button and the other wire to the other side. This will do here. What will this do?
As if the key were automatic when it identifies the battery here is charged it will send 12 volts to release arming and it will turn on the button when the battery is discharged it will disarm this little button So I can now assemble it here I will show the relay connection so you can see how simple it is also the output that comes out From the inverter we connect to 87 and 30, the four-pin 12 V relay came out of the inverter in 87 and 30, there is no order, it can be like this or that, there is no problem, ok, the output 85 and 86 85 86 has no order It's also power, which is the bottom part, it goes to the 12 V, it's what goes in reverse, to the controller, so you can see a wire, I already connected it to the controller and the battery is charged, so it's as if the lamp was on, okay? When I turn it on, I'll even put it on so you can hear it, it'll make a click, oh, it turns on if I take it off and then it turns off, so it's like I'm turning on the switch, turning it off, okay, so we're going to connect it here, connected, okay, we're already connected here to the inverter and now we're going to connect the inverter cables back, which is from the battery, to feed the inverter again, the inverter will already be connected because it's connected here to the loud and aloud is supplying power here, already making the cool key, it already shows with the inverter it's connected, okay? I can try to tell him here that it won't turn off, it's not obeying here anymore So guys, just turn it off here and then it turns off I have to turn it on here but the controller is already controlling it Ok, so the controller is already controlling the inverter if the battery discharge or charge it will turn on or off the battery there are settings but I think it is better for another video showing this video is very big but it's very simple and there are other videos even on the internet teaching how to configure the output load the battery charge Ok so now guys we can turn it on again o the fridge is already on again compressor it's working So guys everything is working now automatically the solar panel is charging the battery the controller is already managing the inverter, if the battery discharges it will turn off the load output and the low output will turn off the inverter battery has charged again guys it will turn on the load output will turn on the inverter is already working automatically, our solar panel system with the batteries And then you ask me and at night what would be a really cool way for us to solve this would be to automate it, we put a contactor but I think that it would be too big for this video, place the contractor so that when the solar energy system is not producing during the day, when it arrives at night it stops producing, it switches to the automatic electrical grid, it's just through a very simple contactor, this is also very simple, or if If you don't want to do this, just take advantage of the day's energy, we can turn the refrigerator to maximum during the day it will work at maximum, freezing it as much as possible and at night it can stay off all night and the next day it turns back on again when the sun comes out, but the personal ideal is for us to connect to the electricity grid and keep creating a contactor system that makes the automatic transfer very simple.
I also think it fits in another video, but this way, if the person wants to use it, it's possible because it put the refrigerator on maximum it works at maximum all day it freezes and takes the temperature it does not lower the temperature to many degrees and it supports the whole night freezing it's on Let's show the battery charge Then, even if it's cloudy, the battery is still charged 12. 9 loading cloudy show it so people can see the weather it's cloudy look there cloudy there's no sun battery fully charged refrigerator working oh I'm going to put it here so you can hear the noise [Music] so the fridge is already on and this fridge here guys could work all day like I'm showing you even when it's cloudy at most and at night it stays on all night if we want to set it up with bigger batteries it lasts even longer even if it's cloudy for an hour It rained and such the battery sustains as soon as the battery goes out a little sun charges the battery another personal idea that would be really cool this battery here guys, it's a little scrap iron flag that I got Even though it's charging it has 12. 5 volts but it can't start but you want a scrap battery but for this one system to regulate it works, so if you don't want to start it, you don't need to buy a new battery, this battery works perfectly now guys, I brought this fan here, I'm going to even turn it on and the refrigerator is on, it's working, I'm going to turn on the fan more and the system can still stay even if it's cloudy 12.
6 is 12. 6 and 6 and a half amps of charge is charging solar panel my friends if you mount it with a nice battery a bigger battery You can run a refrigerator like this all day You can run a fan You can run TV These three things you can work together with just the panel now can you imagine guys if you set up more panels just think about the amount of equipment you can connect to this system without connecting anything to the network if it is automatic and what do you need you need guys It's not zeroing out your account, you simply need to spend enough to reach the minimum rate that we need from the electricity grid, right ? we turn it on and everything works so it works as a backup, even the systems, a Grid that people are setting up, but today companies set up the system, it's a Grid, it's connected to the network They pay a minimum fee, the important thing is that we take the bill up to the amount of the minimum rate, you know, so this way it's just a North that I'm passing on to you, there's a lot of things, we're going to continue showing you the panels Where to buy, so be very careful at MercadoLivre which is having a lot of scams So I'll leave the personal links to places you can buy without worry, especially on Mercado Livre, there's a way to filter the sellers, my solar house in Belo Horizonte has the website and they also sell the panels on MercadoLivre It's Aldo solar, there's the website, I think Nelson solar, too, people buy from these people, there are people on Mercado Livre selling panels, advertising there just to collect the shipping from the person, so he gets in touch with you, now you have to deposit the shipping, I'll give you one account is it the pix or is it an account for you to transfer you transfer it to him he doesn't send you a panel and you lost shipping we only have to buy from those who have a good reputation they already have more than 100 sales per year 200 sales per year ok be wary of very low prices, we can get them on promotion, just like I'm talking to you.
This panel was purchased at my solar house in Belo Horizonte on the free market, they have it. If you don't understand buying online, ask someone who understands so you don't take loss Then you can buy everything, I'll leave the logical links, the prices change, it was 750 today . you are the values that I bought everything correctly the panel made 750 R$ 500 this inverter and it is R$ 500 Okay so with such a large investment you can set up a solar system to supply a large part of your house and suddenly you can even enter for minimum rate Ok, this video here guys is a guide for you to understand the basics of how the solar panel works, it lasts for many years, it doesn't defect for many years, it's ok battery, it could be a used car battery, it would be even better if you buy it from the iron old, a battery that still takes a charge but is no longer useful for the car but that you can use, like the one I already tested, it also works ok, but this video on how to connect a refrigerator to a car battery on a motorcycle battery is exactly for that purpose.
