00:00 If you keep this panel, you will change your output voltage of the field.
00:05 That's why he asks, do you want to adopt the voltage of the panels as the output voltage of the field?
00:12 If we say yes, he will take it into consideration and modify the output voltage.
00:20 If we say no, we want to keep our voltage as the standard, we say no.
00:28 He will send us a second message.
00:32 You see, there is a change at 24 volts.
00:41 Because there we were on the voltage levels of the panels of the voltage levels of 24.
00:46 So we're going to go in and change in the panel.
00:51 Because if we keep this panel, there is no problem.
00:55 He warns you just on that.
01:00 If you wanted to go out in 12 or you wanted to respect the standard of 12, as we know,
01:08 he warns you that with this panel, it is no longer possible.
01:14 So what we do, we will modify, we take the voltage of the level of 12.
01:20 We take the 130, the voltage of the level of 12.
01:27 And we restart the calculation.
01:32 Now it's good, for the wave, he checked, there is no error.
01:38 Now he gives us a instruction.
01:41 We have another instruction on the regulators.
01:46 You can see it displayed in blue.
01:51 He tells you that the constraint on the regulator with the system you currently have,
01:58 the constraint on the regulator is that you have to use only one regulator.
02:07 The ideal in a project is to use a regulator.
02:10 Do not get into the configuration of using several regulators.
02:16 The ideal is to use only one regulator.
02:20 He tells you that your regulator must respect the constraints he has just given.
02:28 We must have a current greater than 85A.
02:32 And a UPV greater than 12V.
02:39 Is that what we have here?
02:42 No.
02:43 It's not that.
02:44 It means that if we continue with these regulators, if the software recommends several regulators,
02:49 we will have to use several regulators in our system.
02:53 Ah, okay.
02:55 We can continue like that.
02:57 But at the end, if you look at the results table, you will see that he will say,
03:01 such number of regulators, he will give several regulators to use.
03:07 But in this constraint here, it is to use one regulator.
03:16 What I'm going to do, I'm going to see how to lower the current.
03:22 The current?
03:23 Yes, because the current is great.
03:25 I think we can play on the panels.
03:30 Because the panels that we have used are the panels of 7A.
03:37 We have the panels of 7A.
03:41 Almost 7A.
03:43 The panels of 7A.
03:47 It means that ...
03:49 Wait, I'll look.
03:51 Yes, our concern here is precisely ...
04:03 Because to keep the output voltage level,
04:11 we have the panels of 130V, but which give us a lot of branches.
04:17 You know that more branches also increases the current.
04:23 Yes.
04:25 You see, the reason that can lead you, for example, to say that I rather adopt the voltages,
04:31 I rather adopt another level of voltage.
04:36 Yes.
04:38 I don't know if you see a little.
04:41 Yes, to compensate a little for the current.
04:45 Yes, the current is high.
04:48 So when you take the software, it does a calculation and a quick simulation.
04:52 It tells you directly.
04:55 Even as we will have the large simulation at the end to see the output and everything.
04:59 But directly, as it is with the regulator, there are the problems in a PV system,
05:04 which are usually the regulator.
05:06 It's often a problem.
05:08 It does directly and advises you what to do.
05:15 There was a call that cut.
05:19 Who wants to cut us?
05:23 So what we're going to do is that we're going to keep the voltage.
05:29 We keep the 300V panels and we modify the output voltage level.
05:37 I think it will be much less constricting in terms of current.
05:43 So that's what we're going to do.
05:46 I don't know if you understand the explanation of how the software works.
05:50 Yes, I see.
05:52 So if we restart the calculation, we have the same message and we will say yes.
