In this video I will teach you for free how to set up an offgrid solar energy system even with few financial resources without giving up quality items that meet all safety standards and you spend very little. I responded to a request from a friend As Tarcísio said, I'm poor, I have few resources, but I dream of having a solar energy system, even if it's a small system that guarantees me production to save money during the day, in case of a blackout, turn on a fan, connect some lamps, a TV connected for a few hours help me and then we will teach you step by step I'm telling you that you will see all the items here connected I will set up this mini system spending little if you spend a lot you will spend about R 900 on equipment along with the solar plate inverter charge controller mppt and still taking advantage of an old car battery a battery that can still be used for this little system see now let's get started I'll teach you how to assemble everything Let's start with two plates the solar panels that's what the we need it for generation, so for this small system you will work with either two 100w boards or two 150w boards, preferably working with the 150w ones which at the moment we can find on some websites starting at R 250. So you go spend around R 500 with two 150 w plates, we are going to work with a small pure sine wave inverter, we did a test on this channel, which gives about 450 460 real w, which is enough to connect a fan like this , light bulbs a blender a TV a router not letting this load pass through that we said maximum 450 w So let's use less and use pure sine wave quality Remembering that all the links here are in the video description we will also use a controller mppt charge yes You will work with mppt Real there is a video on the channel showing that it is a real mppt that will take advantage of the maximum quality of the production of your boards, the maximum power from them to charge your battery bank and this mppt at the time we paid 129 and today on average ranging from 140 to 150 and we will leave some options of this same mppt with different brands also for you to save, we will not give up safety items such as the DPS DC and the DC circuit breakers on the boards and the battery and we will take advantage of it Since it is to save money so that those who have few financial resources can set up their system you will save on batteries you will get two car batteries there they can be used but still work properly two 60 Amp batteries get them in your city for a little price cheap way to set up your solar energy system, let's now start with assembling this system, come on guys, let's get to work straight away because your system isn't there, you bought your two plates, either 100 w or 150, what are you going to do when You buy the boards here, I had already left it more or less fixed, it comes like this, a 100 or 150 board here will change just a little bit in size from one to another They will come like this, what are you going to do, there is a positive connector and negative, each with a type of fitting, you will take the positive of one and fit it to the negative of the other, it only fits one way, there is no way to go wrong, you got the po You just can't take both of them from the board and close them, but you took the positive of one with the negative of the other or vice versa, connected one to the other with this connector called MC4 and that's it, here it has a little dent, just give it a little squeeze, new board, that's how it is, let's take the other one here and invert it, that's it, you got the positive MC4 here from one negative to the other there will be two ends left, one positive and one negative, where are we going to connect this to the PV input of the charge controller, which is the charge controller ? higher when you take a plate like this If you take a Zinho meter and measure the voltage the volts of this plate here it will give an average of 22 v then when exposed to the sun a plate like this When you put it in series it will give more or less 44 V will add the voltage to the voltage And then your battery in this case here will be 12 V let's use two 60 to 12 V batteries in parallel and how are we going to connect these 44 V in a bank of 12 v, we will use the mppt charge controller, it will take these 40 and a few volts from these two plas in series and will regulate the voltage, it will send between 13.8 to 14.4 v to this battery bank and it will be used This voltage on the plates, which varies according to the intensity of the sun, will leave it unavailable in your battery and even more so when it is MPPT, different from PWM. They are two different technologies. It will take advantage of this remaining voltage . of 12.6 which is 13 is the voltage of the battery bank but it works with two voltages 13.8 and 14.4 and what it does is there is a lot of voltage I will reduce it and I will take advantage of it I will transform this excess voltage these 44 into Current So, more current will come to the battery bank, if it were the PW, you wouldn't lose it, you would just regulate it, the maximum nominal current of the board would go to that bank and in the mppt we will make the most of it So you connected the solar panels here to the PV input of the controller and the output here goes to the battery bank And you already have part of your system connected, we are going to make this connection, but you connected the two boards, insert a reserve here in the corner so we can make this connection to the mppt charge controller now, let's go reserve the plates here already connected in series and we will make the connection to the mppt now we will start with another part of the assembly we will assemble Here the battery bank two automotive batteries Let's put it in parallel and we will connect it to the inverter and let's see now very close like this assembly here, look guys, we put the two 12 V 60 Amp batteries here and we're going to connect them in parallel, as it's parallel guys, we're going to take the positive of one battery and connect it to the positive of the other, we're going to take the negative of one and connect it to the negative of the other and then we will get the same voltage 12.6 V which is the nominal voltage of the battery but we will double the current 60 + 60 120 ah in this lead battery bank when we go to this assembly made the connection here between the two batteries see two positive poles interconnected two negative poles interconnected What are we going to do first, take our inverter, which is the inverter, it will take the current, the energy from these 12.6 batteries, and will transform it into alternating current that feeds your blender your TV 110 or 220 You choose it has input 12 and then you choose the output when buying I want my network is 220 you will buy the output 220 my network is 127 So you will buy the output 127 What is important This one is a pure sine wave, the wave is pretty round, just like the one used by the dealership for your devices to work Ok, and 60 Hz is the speed that this wave makes in one minute, in one minute, 60 waves per minute, 60 hz per minute, not per second, and that's it. within the standards 60 R pure sine wave we connected this inverter here on the battery bank if we Fer this now with the cables that come with it let's connect it here we already have a voltage here we already have a little system working charged batteries connected on the inverter It took a few seconds there will be 110 or 220 V here the solar energy system is ready, isn't it ready the first stage here of the inverter with the battery let's assemble what are you going to do that I'm not going to do here you'll get it the negative cable from the battery bank will connect here to the inverter and the positive one you can use a single-pole circuit breaker to be able to put between this cable here, cut and connect a circuit breaker between the inverter and the battery bank, generally it is a one circuit breaker of a high current 80 100 aamp to be able to protect your low system here for educational purposes I will connect directly here but you know that you have to have a Zinho circuit breaker between here and on the Positive between the positive of the inverter and the positive of the battery bank Let's get this assembly ready guys, here we connect the positive of the inverter from the inverter input here to the positive of the batteries and the negative of the inverter input to the negative here of the battery connecting the inverter Zinho here, he turned it on, the light turned green, it's ready 12 V coming in is already coming out 127 here we can feed some load to this inverter Zinho Don't do that I'm trying to connect a wire here just to show that it's connected but then you run the risk of making a short ol It's connected there's voltage to be here we go For the next step, here the batteries are already working with a load, the inverter is working You could connect several loads here and it would work, but that's what will happen without the solar energy system on the plates charging this system Ah, you were using it using the batteries discharging the inverter would shut down you would run out of energy now we are going to assemble the plate cisterns which are used for charging the batteries And during the day when it has a lot of energy in addition to charging the batteries you can use the plates' own energy DC that will be converted into this system so that during the day, in addition to charging, you also use the energy from the plates to power your load directly. So let's do the step now from the solar panels to get to this battery bank, get to this inverter to start the new step here what we need the Zinho mppt charge controller that I already explained to you and an MC4 cabin that you can buy ready-made or assemble buy the connectors and assemble there is a video on the channel teaching you what we need will do it inside the mppt charge controller, it has the PV input inputs which is for connecting the solar panels and the battery output has a load output which we then say is for powering a small lamp, a small thing but what matters here is We're going to connect this little cable here from the solar panel input here to the PV input of the mppt and then we're going to connect its output to the battery bank, we're going to strip the 6 mm wire and we're going to put it here at the PV input, observing the polarity more and less correctly, here, see and a note the solar board will be the last item you will connect to it first you will connect these wires then you will connect it to the battery bank and lastly the solar panels here so as not to damage your mppt charge controller stopped stopped stopped guys, it would be that simple, right, connect the Mc cables here I even already stripped it, I took pliers, oh poof, I took off the little tips here, stripping it so you can connect it here, but then we wouldn't have our protection What is the protection that the We are going to use it in the solar energy system Before connecting this little cable here to the MPPT, before connecting this cable we are going to use this little protection system, it is called the DPS, which is the device against surges, what is an outbreak, imagine your little plates on top of the house and then a storm comes a flash of lightning everything then this little electromagnetic wave this discharge can cause the voltage at the output of the plates to rise to a very high level and could burn the mppt charge controller So before the plates arrive at the controller we will pass this wire from the boards through a DC circuit breaker and the circuit breaker that we can turn off is already a protection against shorts on the boards the circuit breaker goes down more and less and at the output of this circuit breaker we will turn on the DPS this DPS when it detects that the voltage has become too high, instead of letting it pass to the charge controller, which will send this same current to the battery, it will direct this surge to the ground, we will take a ground wire, put a grounding bar on the ground and it will pull that little green wire and connect it here to the DPS output and the connection is simple, see the negative circuit breaker output goes to the negative input of the DPS the positive output of the circuit breaker goes to the positive input of the DPS And then, in parallel, the little wire goes here to go, yes and for the mppt we will connect this output here to the PV input of the mppt and the Zinho connector on the boards that went directly there would be left without protection, come here, the plus and minus of the Cabinho MC4 comes to the circuit breaker to come down from the circuit breaker comes here to the DPS and at the top output of the DPS it goes to the mppt charge controller, let's make this connection and you'll see how pretty it looks, look, look, how it's already looking nice and still simple, the plate entry cabin here, look at the path of the cable Input of the plates we connect them positive to the positive of the circuit breaker negative to the negative of the circuit breaker negative of the circuit breaker to the negative of the DPS up here positive of the circuit breaker to the output of the circuit breaker to the positive input of the DPS remember that there are only two cables here, one in parallel on the other side, here on top of the DPS, there is the same cable that is spliced here in this negative that comes from the circuit breaker and comes to negative input minus the PV of the controller carries PV input which is PV photovoltaic panel and the positive Zinho here is from the positive terminal of the DPS which is the same as the positive output of the DC circuit breaker comes here making the curve at the input plus PV of the controller load and here, the Green cable, the ground output goes to the ground bar to protect it from the surge, if it comes to the normal voltage on the plates, 40 V goes through, cute, there was a surge, 1000 V, this 1000 will go through here, it arrives at the DPS, it goes to the ground, it doesn't burn the mppt it doesn't even give a protected shock Ready and what are we going to do now the output to the battery bank we are going to connect we are going to connect now the mppt output of the solar charge controller to the battery bank and the first thing before connecting the photovoltaic board you have to connect the battery bank here to the charge controller, what are we going to do, let's get another DC circuit breaker and let's put it here at the battery output of the charge controller, take the Cable here, the positive of the battery output of the controller on the Positive of the negative output circuit breaker hits the controller on the negative and then at the output of this circuit breaker we will connect directly to the battery bank to connect the charging controller to the battery bank And then we will use the boards to pass through the controller and charge the battery bank and power the inverter, now let's do this here, another step completed guys, we connect here the output hits the circuit breaker and from the circuit breaker it came to the positive battery bank Zinho of the battery on the Positive of the circuit breaker the circuit breaker here the positive output on Battery positive same thing negative on negative circuit breaker negative output circuit breaker on battery bank negative circuit breaker is off for protection the mppt is off if I connect the battery bank here what will happen turned on the charge controller now the charge controller Have you already got your reference bank of 12 and now I can connect the solar panels But let's go into detail about the circuit breaker What is the current of the circuit breaker is it a direct current circuit breaker the link is there in the description of the video battery circuit breaker solar plate circuit breaker circuit breaker of the inverter, everything is fine and in this case here are two 150 w plates in series I will have 44 4 V for 8 A 9 Amp current So I will put a 10 circuit breaker to protect here 10 Amp to protect this little system Desc of 10 Amp PR input of these two 150 boards in series the DPS its description is there you just take it from the solar DPS and put it in this little system and the output here from the mppt controller to the battery bank as a rule the current from your controller output is maximum 20 Amp circuit breaker of 20 is 60 to at least a circuit breaker of 60 is 80 to circuit breaker of 80 to protect the maximum current then just to protect this charge controller from short circuit and in this case here the mppt one of 20 so we put it circuit breaker Desc of 20 to like this inverter here it pulls more or less there to give its 400 V it pulls around 40 to 50 Amps from this battery bank to the maximum it supports so we would put it there and cut a little red wire Here I would place between them a minimum 50 Amp circuit breaker for this little system and it would already be sized so what are we going to do here, take the terminals left over from the solar panels and fit them there to the Zinho MC4 connector of the charge controller at the end of our connection system here for the plates, took the cable, the tip joined the two as I said at the beginning of the video, positive from one to the negative, to the other, two tips remain, there will be a positive tip left, it is a negative tip, the positive tip connects here to the positive terminal of the MC4 and the negative tip here, at the negative input of the MC4, connected this little cable here, it's giving me trouble, connected it here, made the connection there, ready, while it's daytime, your signs are in the sun, don't let them get shade, don't put the block on the side, don't put anything in, find a way not to getting shade on the plate, shadow kills the plate, even if it's just a little bit of shade, it's terrible, so if you attach it with a very low clip, don't let it create a shadow on your plates, your plate has to get all the sun in that blue area, which is the silicon, you put it there. 300 W peak is coming to this system and it will be sending the maximum something to the battery bank around 20 if you divide the 300 w peak by 14.4 which is the maximum voltage that we will send to this battery bank you will have a generation of 20 / h to charge this bank it is a small solar energy system for those who don't want to spend a lot, have few financial resources and want to have access to a solar energy system and for you girls out there who want to set up the system, I'll also give you a quick review here on the panoramic call with your cell phone so you can see what it's like. easy, easy, let's go, my people, Zinha panoramic view there for the girls, for the students who want to make their little system for a science fair, show the teacher there how this system works, let's go here, MC4 entries, we got here the final result of the series association of these two plates and let's enter this MC4 connection, it will go through a DC circuit breaker, the plus and minus 10 aamp Zinho circuit breaker , why? successively See the negative output of the circuit breaker goes to the negative input of the DPS the positive output of the circuit breaker goes to the positive input of the DPS and is in parallel ol the two cables are together in the same little hole here in the connection And then it comes out above the DPS comes here at the PV input input of photovoltaic panels of the charge controller both in the negative and in the Positive PV input and this part here the grounding is connected to the wire in an earth bar connected to the ground and then there is protection against shorts that come from there. on the roof, if there is a surge, a high voltage that comes from it will go to ground, the DPS will throw this voltage there to ground instead of sending it to the charge controller and at the battery output there is a negative output with this little white wire with the little black one representing it. and the positive output comes to the battery bank before putting on the circuit breaker the controller is 20 Amp the maximum that comes out here is 20 Amp so 20 Amp Zinho circuit breaker on the negative input on the positive input of the circuit breaker And then it goes to the positive on the Positive from the battery bank that the batteries are in parallel and The negative here in the negative of the battery bank And then directly from the battery bank comes the Thick wire that goes to the inverter plus here positive input of the inverter negative of the battery bank in the negative of the inverter turned on the inverter Zinho waited a few seconds this voltage here when you turn it on it starts from zero and goes up until it reaches 127 or 220 V it takes about 6 to 7 seconds after 6 to 7 seconds Ok just connect it here and it's ready it has 110 or 220 for you to connect your loads, there is a more complex automation system, there is solar automation, we will install a board or an ATS switch that will monitor the battery bank and if the battery bank discharges too much, it will take it out of the inverter and throw it at the dealership, somewhere where there is a dealership, but then there are other stages of the system that we won't talk about today, then your solar energy system is set up with the main equipment, mppt inverter boards, you spent them and disassembled them, DPS, more or less R$ 900 is the batteries if used used have a better battery today is Live po4 they are batteries that last 10 to 12 years much safer they are more expensive than aum bast in relation to the initial investment but later they become cheaper because you use countless times more than these pellet batteries, but for a beginner system, one who does not have financial resources and wants to have a solar energy system, yes it is possible, we show you how to set it up if you follow step by step here you have your solar energy generation for feed some loads cool Oh wait, let's connect here just to show that it's working get a reflector I could here Turn on the fan I could turn on a lot of things ap Ah, I can connect a refrigerator, you can guys, it depends, this inverter can't handle a regular refrigerator, but there are inverters that can. So, let me leave the inverters that can handle in the video description. If you want an inverter that can handle a refrigerator, you will remove this bug here and put in a more robust one that can handle a refrigerator with greater power and your refrigerator will work according to the investment you make, you want to save money, turn on this 400 w one, turn on a lot of things fans lamps router TV receiver some blender some rice cooker do you want to put a more powerful one to connect a fridge beauty just change it, it arrived, my people, today the shout out is for all the friends subscribed here on the channel, we prove that it is possible to set up a system of solar energy, even with few financial resources, you can use an MPPT, a good Zinho charge controller, a small Zinho inverter on the pure sinusoidal two small plates of 150 W and you can still send 20 Amp h to a battery bank during the day generate savings Connect some loads and in case of a Blackout Do you have an energy reserve for that moment so as not to be left in the dark turn on a fan and also generate savings? Yes, it is possible to take advantage of some car batteries . the offgrid system is the Live po4, it's worth every penny the investment And then in a little system like this you want to put a Life po4 stool of 30 40 50 Amps, there's a class here on the channel how to assemble this Zinho stool, four Life po4 cells for those who don't know how to Those who still don't know, it's a lithium iron phosphate battery that has been around for over 10 years, you can discharge more than 80% of it, it's worth a lot and your system has much greater autonomy, but it's robust and more durable, so you can get it. this is the system that we taught you how to set up and just change those two 60 batteries for a Live po4 stool, calmly, a quick message, right now we have Blue's promotions on Planet Earth's day with 40% off on several devices, check out the list in the video description and in the comments there are bluet equipment at the moment we also have Kingo's Live p 4 batteries on sale, free shipping on the ever R 330 R 3 330 and something with free shipping Top There are cost-benefit batteries from Lit Cala for R20 and a little R$30 too and the tip is at Litocar buy them one at a time, at least every day, buy one here, no, you buy them four at a time, they send them separately and for If you are already a member of the channel, you want to participate in the draw at the eb3 station and at PV 1220, just go to the subscription tab on the channel's main page, subscription tab, there will be a post with this draw and you go there and choose your hundred then I will make a complete video showing how to get there, choose your centen, there was no individual save, very tiring today, the video came out late, it's good, it's still a little weak today, big hug, see you next time
