So
, guys, how are you, today, we're going to bring you the complete wiring diagram of a well-sized solar system for anyone to assemble, even a layman friend will be able to do it through a solar energy system, this connection here will be able to assemble your system So let's not go waste time and let's go peace explanation and all the components dimensioning of all the components of this system and in the end You comment and take the rest of the doubts but everything will be dimensioned there in this system liking the class and the teaching to paste will pay weak like and subscribe to the channel by activating the notification bell just pass the balance at the end of the video let's see the system come on guys I'm bringing you here a yes it's full solar energy well explained we will bring the sizing of all items system here for you to clear up any doubts and even if you have any doubts you can ask them here in the comments as always we here at Finally, we answered our friends who subscribed to a Super Institute system at the same time complete so that anyone, even a layman, is now coming to solar energy will be able to assemble their system quietly, a quality system with few components and that will meet a good demand there, let's start here o we are using two 450 watt boards that will have a power taken and 900 watts peak hour and we are going to work in this system here with our boards associated in series And then what will happen we are going to maintain the current of these boards and we are going to add attention as our 450 boards we have there an attention see mpb41. 4 volts put 10.87 amperes of maximum production current we are going to put it inserts here the negative of one spliced into the Positive of the other, leaving the positive tip that goes here in Now in the solar fuse holder and the other negative tip also here in ours solar fuse holder and we are going to add this voltage and forty-one point 4 goals per board that will not give us here in this Association here in this Spring we will have eight point 8 volts and we will keep the unit current of the board which is 10.77 amperes maximum So here at the end of this circuit breaker here this attention here from the circuit breaker not from the fuse holder only there we will have an attention there of 80 and 2.8 volts maximum peak voltage vmp and only 10. 87 also so now we are going to choose our solar fuse holder solar fuse holder it is very cool because it works with a variable current it accepts the possible ones from 23 amps to the maximum 30 so we will be able to put fuses around 12 amps there And then you will choose see the commercial value as we will have a maximum current circulating in this Spring of 10.77 amps the group cooked there in this range up to 12 amps will quietly protect our circuit So you should look for a fuse around 12 amps or well next to protect our circuit to it decide this circuit here will obey this polarity plus and minus and it will enter here in our DC circuit breaker me current with theme and this circuit breaker will be here in parallel to a DPS our juice device where The negative of the of PS will come here at the output of the circuit breaker to be at the negative output of the circuit breaker it must be and the positive input of the DPS will come here at the positive output of the DC circuit breaker , our DPS there is a connection here that goes to ground has a symbol Zinho de cana do DPS The terminal that goes to our ground bar over the grounding system we have a class here on the channel that is already here on the card there will be some explanatory posts during this vid eo e in this system Here We chose that this grounding of the photovoltaic plates that can suffer atmospheric discharges will have the only isolated ground there with the single rod As I said in the class you will see that you could unify all these groundings in one or three arts together here for safety reasons as already explained at the time I said we are going to choose an individual busbar for this system here for the production of the Plates I'm leaving for there leaving let's not find out now which current we are going to choose our circuit breaker to be current with the theme here of the descent of the plates that comes after the possible protection system as we already know that this current there will also not exceed 10.77 standing, although the plates have a short-circuit current around 11. 47 knots we can also use commercial circuit breakers in the range of 12 amps And then you try to adapt the closest commercial value Remembering that they all have a tolerance not a work tolerance for more then you can choose a circuit breaker very close to this cal Because we are going to pay attention here but it is to take 82. 8 Plus the maximum current that does not reach 11 amps entering our charge controller here. or ml pro that a controller there of 60 amps and it accepts an input voltage here at the PV input panel releases voltages of up to 190 volts so we will be working there with 82 flights 80 and 2.8 with a considerable gap working there a quiet range with the our 60 amp controller over the down current Let's make a calculation here , yes, we have our seven batches in production and we are working without considering the losses . will work in a system that the batteries Where is in series that is the 24 volt bank of 220 amps because we have two batteries of 220 amps and the bank remains only 220 amps because in the sociation in series or of plates or batteries we have the sum of the voltage and the maintenance of the current so attention will form 12 + 12 24 and the bank current will continue to be 220 amps very important time to say this 220 standing hour because you it can be from Picos in a battery like this one with more than 1000 amps, but it will discharge quickly and it's just that it's not the power, the peak current isn't here, it's 220 amps that it can supply in an hour, ready missing here ours the bank is 24 volts but us and send via charge controller an attention and at least 28 comp 8 volts for some time So that the recharge of these batteries occurs So we will divide there the Total power of the plates that gives 900 divided by 28.8 volts and we will have a peak current that will come out here will be going to the output of the controller that goes to the batteries, passing through a bus that is optional but we put it here in our system with a bus we will get a production of 31.25 tampers at 28 volts to charge our battery bank now let's talk about recharging this bank see guys it has a minimum current of 10 to 20 amps for charging so that you can have a healthy charging system some batteries the manufacturer recommends that you can use them and a maximum current of up to 25 percent but we are going to work here between the range of ten to twenty percent percent if you look at 10 percent of this bank of batteries here it would give 22 amps at 28.8 volts but if you calculate the twenty percent it would give 44 tampere so we work here with the recharge around thirty-one point 25 amps we go to be working between the minimum and maximum limit there already very close to the maximum with a reasonable current so that we can charge our batteries and there is a high consumption during the day let's talk a p little bit now from our sharpening sharpening here usually from solar panels we should use a 6 mm cable the ideal is to use solar grass yes who can spend with solar grass which have a greater resistance to more than 1000 I'm going to go down there's one more special is more resistant to the sun but it is more expensive it can work and this wire works with currents above 36 amps and who can't, we have there the guy made common girls that he has an insulation There depending on the brand around 800 votes he it doesn't have a protective mesh and it's not so resistant to the sun when it's sunny but it works there quietly without any loss well assembled everything right so you can work here with 6mm heat here from the boards to the Audi fuse holder together like this from the boards Hello all with 6 thousand meters until the entrance of our charge controller put it Mr pro or m60 pro new with Mr there, now see what the gauge of the wire here from the controller to the battery bank this controller accepts and wires between 3mm to minus plus six is what we recommend the minimum between spray to 25mm for them the current here decide a 16mm wire would be well dimensioned because it will get there up to 68 amps as we are going to work and with peaks and 31. 25 amperes would still have a slack for future expansion of the production system without compromising the assembly so you can work quietly with 6mm both from the controller to the bus and from the bus to the battery bank and that same 16mm cable can be used in ours an inverter and I'll explain why because in this project here we only put a 1,500 inverter, the general oil reaching 3,000 with what we could work there with this current here of 68 amps, it would easily pass even the production we need for this inverter we are going to do a simple calculation here where we can take the power port of the inverter 1500 Watts y the nominal power if we are going to use all the nominal power 1500 o glasses and let's go And then for 24 volts that would be the minimum voltage of the battery bank we will have 1500 watts of power 6 inverter divided by 24 flight we will have a current drained from the battery bank around 62 Ton 5 amperes we put here so a 63 amp circuit breaker and the 16mm cables that would easily supply 68 amps there must be they would not be very close to the limit no I will explain why we work here with the nominal 1500 inverter but the manufacturer recommends that we use at least Twenty percent at least continuously That is, we would be working with the 1,200 lots, I'm still real and then I'll have a very high clearance and then you can see if you need more and at the peak than the peak at 3,000 years, but everyone circuit breaker these cars It works quietly in these peak currents why Because this peak here is very fast it doesn't reach seconds sometimes milliseconds that is and hates it together it has an actuation time and it has a margin and it is dimensioned to work with these peaks we must dimension it not by the current or the peak current voltages but by the nominal because these peaks are very fast well so let's continue here a second grounding that we did here we made the grounding of the battery bank that will already be connected here to the controller and another individual bar Remembering that a sol bar could have unified the grounds but for safety reasons and the option Wow, we separate the grounding by block a block from the photovoltaic panel another charge controller battery block and another grounding here that you will see already on the inverter housing let's ask me if I could work there with that is this higher power inverter you can yes it's just you don't necessarily have to putting it on top of your little one here you can scale a bigger inverter and in the future when you can put more batteries and more boards there you will do the some and like the cabling that didn't invest there I'll give an example universe then it opens the 3000-hour Label we use it here already the 100 amp circuit breaker without the 125 amp and I'll explain later why in another dimensioning and the cable of 25 millimeters that would be fine, but if you are going to use this one, you can easily take the 16-volt path that will go up there, these fifteen hundred, we have it here, but the output of our inverter has already converted the 24 volts to 110 or 220 because I say that because the system here you can work with any Attention if you want or 110 127 220 volts because all this here we just go mode and getting some scaling of the current all the positives work with these two voltages and then you will choose according to your equipment with your equipment, that is, your load that you will connect at your house beer that the system is very dry any layman assembles a witness of it here calmly Let's go , here's an example of a voltage output at 127 volts So there's another class here on the channel where I talk about the sizing of this circuit breaker to protect the inverter you don't burn the inverter due to an overload using a safe calculation I decided to join it here output to be and how do we do it here see in this case here we are going to work now with the voltage 127 volts And if I have this inverter manufacturers ask me to work with it then form with Tina with a margin of twenty percent So I'm going to remove the videos percent of 1,500 here, which will give 300 , the other one will be left with 1,200 so I'm going to dimension this circuit breaker here for 1,200 the glasses because it can work with 1,500 for a while, but it also made it work with 1,500 during one longer this circuit breaker it will even trip protecting your English because it is not black to work in a way Confirms with maximum power then we calculate the 1,200 lots we divide it into 127 volts and we get the output current to be 19.44 amperes they and then you will throw here a circuit breaker there the commercial value of 10 amperes you will be able to work at some point in peak power both at 3,000 vote in a few milliseconds as many one thousand five hundred nominal for a few minutes it goes yes and safely if you work for a long time with it 1500 its tendency to trip that even protecting your inverter so that it doesn't burn easily So for protection reasons to work at 110 Volts with this power then in up to 1,200 lots we put the circuit breaker there to be 10 amperes to cover this current there of 9.44 amperes in current as and see guys it's not Thai class but this investor here he doesn't typically have a neutral output and they don't inverters usually this output is alternating one side and neutral f Hi and then later we will talk about the reference to ground to define a standard neutron but for now keep observing here that I even put the same colors because by now it will be about to be phase here already I put it here in the system that goes to our automation to neutral EA Tell yours to identify the input terminals let's go then we already have the sizing here of the circuit breaker And then you say Tarcísio and the gauge of the output wires to be seen guys we have a current and maximum that we will work with 10 amps and that at 127 volts so a wire of 1.5 millimeters we can work up to - _ _ _ mail and an e-mail you can choose without having to spend a lot I would like the digital relay inside the March because I put this digital relay here I could work here with the delay relay because to explain air for a lay person who wants to assemble his system here from scratch this inverter when we turn it on here it will take a few seconds so attention is worth zero volts here at the output from 0 volts to 127 KC and this we feed ours appliances with this attention with rising is not good for appliances for Home appliances there is already a class on the channel about this here I'll even leave another Card here about this phenomenon But going back, ideally, we delay Figure this inverter voltage before reaching this key here and go to Home appliances automation until it stabilizes then we can use this relay here called digital relief and here there is also a complete class on configuration and about it here that I will also leave on the other Card above and it will do this protection function by holding it there for a few seconds that you program this is this attention until it stabilizes and after it stabilizes it will count 5 seconds and go l Iberar this attention to our automation via ETs switch because you I could have placed here the digital relay a contactor a battery bank monitoring plate to do automation, yes quietly, but the switch alone has all this together not only device and it makes it much easier to assembly mainly for the more lay friends on the subject and then with a very lean assembly very simple It even does all this automation it will have the output here that goes and in the battery bank see positive here from the bank at 24 volts there will be a little entry here from the positive or negative bank will come in the negative here of the 24 volts and she will monitor this attention of the battery bank to define if attention here in her output that she has an output here she will be working either with the dealership or with an inverter if I battery voltage is within what you configured it will switch to solar energy when this battery voltage is lower it will monitor the attention here tion and goes to switch the air to the dealership indicating that its solar production is already low and its batteries are already discharged And then it will do this ultra-fast automation through relays here inside it all inside this box in a super fast complete automation in one device it's only here that the public energy or utility input comes back to drinking wine here to make it easier and it has an indication here of the neutral of the utility's phase it has here the input of attention coming from the inverter of the solar energy voltage inverter and it has here the general output where hours will have energy from the utility, time will have energy from the inverter of the solar energy system and who will say that attention of the battery bank where you user will configure here via digital commands attention that will start the transfer and attention that it it will transfer again to the dealership when the battery voltage is below the level you programmed the other day it has charged it has gone through two times example 28 points the four flights went up it went from that she tea what goes into solar energy again who will do all the automation work there is this key let's just review this system with the battery bank there of 24 volts in 220 amperes hour of discharge capacity what would it be without solar production solar production is over you would have a healthy discharge from this bank of between 20 and 11 amperes per hour what would this give you multiply these 11 amperes per hour times attention there from the bank at 24 goals you would have a possible discharge around let's do the calculation here quick it's around 24 volts let's go there for you to make a healthy discharge of your battery bank 24 volts 1311 amperes we would have around 264 votes For now we we're talking don't go out in the area there is already solar production and not to run out for your battery Your battery bank has a reasonable life span making a discharge and controlled in servent of 264 several per hour when the power stopped production of solar energy you will have your battery lasting much longer during the day with the production Of course you will be producing 31.25 amperes per hour peak you will have your bank there already charged So you will be able to use it with solar production much more power the discharge point to be controlled during the night so that you can keep your battery bank healthy there we have other classes on the subject at the moment we are here bringing this little solar energy system to the Lei do Bem Simple there for friends mount in the description of the video as always we leave exactly all these items here with the best discounts that the site sends to the
