You will now follow in this video the autonomy of this Growatt battery that is here with us in the laboratory I brought a complete review of this battery I showed the inside I showed a series of details and a lot of people but a lot of people are asking me about the autonomy issue, How long does this battery last What is its autonomy? How many hours can I connect certain equipment? And then I have a very interesting tip to share with you.
which is the number of hours it will last Here This battery will directly depend on how much energy you will demand from it instantly This is a very good tip important tip, very interesting, it deserves your super top like and it deserves that you stay until the end of the video to learn more, it's still good "and what this means Eduardo, explains it a little better", it means the following: This Growatt battery that is here with us is a 5kWh battery of stored energy is 5kWh nominal and usable 90% of dod so that is 90% of 5000w gives 4500w the calculation is very simple is 5000 x 0. 9 which is the depth of discharge which is the maximum dod that we can do, we will be left with 4500w of usable energy, then you just take the 4500w and divide it by the instantaneous power that you are using in your inverter and then you will know the number of hours that will take place throughout the video here we will show you more details and at the end I will teach you a super easy formula for you to do the calculations Based on what we will see in this battery here we have it here also the grovt inverter has the SPF of 5000W and 5000W. However, we are going to put around 2300W here instantly so that we can extract it from this battery instantly And then we will see more or less how long it will take give is more or less 1h40 minutes approximately maybe 1h35 1h40 more or less ok, I explained all this to you now I'm going to show you here how our setup is how this connection is made so we can do this autonomy test of this battery from gruat which is here with us for testing and to help you make the best decision so we have the battery here as you can see it is the AX 5.
0 lc1 battery OK it is connected to the SPF 5000 inverter and we have between the battery and the inverter this wattmeter here that will show us voltage instantaneous power instantaneous current and energy in wat and we will also leave this cell phone here so we can see the time we are going to start when I carry out this process I'm going to record a time lapse here for you and then you'll see it in a very accelerated way without interruption, we'll see the time it will start and we'll also see here the time it will end And then we'll see if it goes get close to 1h40 extracting from this battery more or less about 2,300 2600 620 2,600 w more or less it will say 2,300 but 2300 is on the AC side 2,600 on the direct current side, okay and we are going to evaluate that now, well then I'll go do the following I'm going to put it here to record the time lapse ok we have it here now 15:51 on the 16th of July ok And here we have our oscilloscope that will show us the details and I'm going to start loading it In our test gig I'm going to put mixed loads Look at capacitive and resistive loads at the same time, ok, connecting several loads here, let's see what it's like here on our oscilloscope we have 1960 w, we'll get to 2300 or 2340 watt on the oscilloscope now let's see how that it's here in our inverter Look at 2660 w more or less and then we'll take this value that's here now of 2630 w more or less and divide it by the 4500 w h usable from this battery and let's see how the behavior will be Look practically Then 15:52 was the time that our tests started and now we're going to leave it recording here so that we can follow it as soon as it's finished I'll come back here with you we have a super cool partnership with Growatt and also a really cool partnership with Fortlev, Fortlev is the distributor that has these batteries with the Growatt off grid kit here in Brazil and we have already made a super cool video with the complete review of the grovt off grid inverter which you will also find along with the Fortlev here in the description we will leave a link to you can get to know a little more about Fortlev and also register there using a super special discount coupon that we got for you, very cool, even if you are not an integrator, installer, no problem, you are an end customer and intend to have this technology in your home, contact Fortlev right now and they will certainly direct you to a more suitable integrator and installer in your region and yes, Fortlev is that water tank company you know, maybe you have a tank water supply from Fortlev the ones from my home, Fortlev, and Fortlev now has the Fortlev Solar line, meeting a very cool demand here in the market, an extremely trustworthy company that is absolutely worth it to you. get in touch with them today and share the mix of products they have to offer in photovoltaic for you to serve your customer [Music] [Music] Look, at 15% the inverter starts to beep here for us, look, just give us the error 04 indicating that the battery is low This is completely normal, look here we are here with practically 1:37 and it has already been removed from the 4230 battery, we are going to leave it here until we reach 90%, I brought this section quickly here to explain to you how the inverter will alarm here due to low voltage due to low capacity in the battery bank, okay, I quickly came back here to show you that the inverter is still beeping, this is normal, it's because the battery is low, our tests here at all the steam and just look at the oscilloscope here, you can see the SPF 5000 inverter and the Growatt and the interesting thing here is that we are already doing a bit of a fire test here on the inverter as well, right? Already taking it there to practically half its nominal power practically and practically there 1h40 spiker show show of ball really look at that 4360Wh actually, right the wat would be instantaneous watch H instant energy look at that 12% will hit spiked 4500 WH that we have there usable in this battery Growatt So we're already in the final stretch here, the countdown to the 4500w usable H of the axess 5.
0 lc1 battery from grova Tin is a 5000 w usable nominal battery 4500 with a dod of 90% and look, look, we're here practically at 90% of dod of our battery, that period that I told you about, more or less, 1 hour between 1h35 and 1h40 1h42, okay, we haven't reached 4500Wh yet, but look, the inverter has just gone into protection, it's already turned off its output. ca Based on its configuration limit, it's 4455 whe, so you must be asking yourself this question, right, Eduardo But then that means that this battery doesn't provide the nominal 4500 w, I'll explain it to you, let me turn everything off here to remove this noise, here it is. It's good to turn it off here, wonderful, it's not quite there, this battery is there, it provides Yes, this usable capacity of 4,500 wh, calmly, you saw that it came very close, there was practically 50 wh, and why didn't it reach 4,500 wh, simple difference in instruments, ok?
battery was probably probably not definitely checked in a laboratory with certified calibrated instrumentation and This instrument that we used here was a simple wattmeter that we buy super cheap on the internet and that is widely used by people on the offgrid, that's why I chose it This wattmeter here is good because then it will come very, very close to the real one that we have here in the battery, this is a great show, we have just seen here that this battery actually delivers its declared nominal capacity, right? In fact, the nominal capacity does not, right? the nominal declared usable capacity of 5000 w declared of 4500 w hey, you might be wondering too, right, you've reached the end of the video and you're probably wondering Wow, but I buy a 5000 whe battery and I can only use 4500 Wow, what if I need to?
using the 5000 wh unfortunately is not recommended in any way to use these 5000 wh, including the inverter will not allow this so that we can maintain a good useful life on this battery in the range of its 6,000 cycles, with a dod of 90%, that's good. It is valid for any type of battery, if you completely discharge it, it drastically reduces the useful life of the batteries, and LiFePO4 is not different will also reduce, however, just look at the amount of energy that we can use from a LiFePO4 battery like this one, 90% is a lot of energy, close to that, the average is 20 to 30% maximum of Lead acid, it's a great show AX 5. 0 lc1 battery from grovt is approved, thank you for the great partnership with grovt, the partnership there also with Fortlev Solar, as I already mentioned to you, okay, strong leve solar was a great facilitator here for us and it will be in the description of this video and also a comment fixed a link for you to go there now and get a quote with forte leve solar using a special discount coupon that we got for you and here on the side more content like this for you to continue here on the channel big hug until the next video next class next tests tips or Episodes of Aquino Responde here on the channel.
Bye!
