00:00 Change our voltage level. And you see that the current under the constraint is almost irrespective of what we have here.
00:07 You see that we have a current of 49. We must have a current greater than 49 and we have a regulator of 50.
00:18 It's good. Voltage on the side of PV of 75 which exceeds 24. It's good too.
00:24 The number of branches has decreased.
00:30 The number of branches has decreased. In fact, the number of branches is because we have increased the voltage of the panels.
00:41 You have here a small summary on the assembly of the system.
00:53 We will go to the table of results as you see there.
01:00 At the level of each equipment, there is first a reminder on the equipment.
01:08 Then, the reminder on the equipment. There is now the number of each equipment to use which is specified.
01:18 We will not dwell on it. I guess it will be a little problem for you to see.
01:26 Hello? We will not dwell on it too much since we already have.
01:33 We come back and there is a first thing to do. Calculating the sections of the cables.
01:43 What are we going to do?
01:46 By default, as I said, the software is configured to work even for someone who does not yet know how to use it.
01:58 What does that mean? By default, it has stopped the values. Look, at first we had started at the level of the choice of the inclination.
02:05 By default, it had stopped a value. So even if we advanced without modifying, we should always have fair results.
02:13 But maybe it does not pose too much the realities of our field.
02:18 We did a round there, we modified. If we did not modify, it should work with the minimum value.
02:22 And we had to choose the inclination of 6 degrees as we saw there. Which is not optimal when we install.
02:29 To make an inclination of 6 degrees, it is slow for all the reasons we mentioned at the beginning.
02:36 Secondly, at the level of the output voltage fixation. It also works with the standard.
02:45 So you do not even have to manage that.
02:48 And thirdly, at the level of calculations of the cable sections. You will realize here in the results.
02:56 Hello?
02:58 Yes, I am here.
03:00 Do you realize here in the results that we already have the cable sections that are specified?
03:06 Ok.
03:09 Here, at the far right up there.
03:12 Okay.
03:15 And you see, to go from the PV field to the wavelength.
03:18 Well, that does not exist. Because according to the one who has already analyzed the configuration of the system.
03:24 He knows that there is no direct connection between the PV field and the wavelength.
03:28 It is according to the configuration. We used a regulator first and all.
03:33 If it was a system where we went directly from the field to the wavelength.
03:38 It should display the cable sections.
03:42 So you see here, field regulator.
03:45 It tells you. So here are the non-standardized sections.
03:49 These are the minimum constraints. These are the minimum constraints to be respected when you choose the sections.
03:56 It is now up to you to do as we often say.
03:59 Take the standard section strictly superior.
04:02 So, we will not go back on that.
04:06 So it tells you, for example, here that you will have to take the sections of more than 10 mm².
04:15 According to a certain price.
04:19 And this, as I told you, he calculated it because he has a default configuration.
04:28 We will go back to this default configuration.
04:31 It is done here, at the level of the connections.
04:35 We will open it to make our own description.
04:41 According to the constraints we have on our site.
04:45 So you will realize that by default, the software is set by default as a goal for determining the cable sections.
04:53 It is set by default.
04:56 Not to exceed a voltage drop in the case of more than 3%.
05:02 This is the first constraint.
05:08 This is the first goal that he sets to respect.
05:12 And secondly, the length of the routes.
05:16 It is said that between the field and the regulator, we have a length of 10 meters.
05:23 You know that all these calculations, the cable sections, the voltage drops, it integrates the length.
05:35 So he says, okay.
05:40 Assuming that we have a maximum length of 10 meters.
05:45 And that we must not exceed a voltage drop of 3%.
05:49 This is the minimum section that you must take.
