00:00:02,590 --> 00:00:05,800
Hi everyone welcome back to this solar energy course.

2
00:00:05,800 --> 00:00:15,310
In the lecture named by solar inverters sledding vote is a device that is used to compare the DC voltage

3
00:00:15,310 --> 00:00:25,670
coming to of parties over TV solar cell into AC voltage given the time constraints.

4
00:00:25,880 --> 00:00:33,980
We will not go into Zane Turner circuitry of the inverter but we will talk about the future of the solar

5
00:00:33,980 --> 00:00:43,770
inverter and its application in it as a model to be v tested now inverter could be classified based

6
00:00:43,800 --> 00:00:51,300
on zero size or even mode of operation or implementation too bullish.

7
00:00:51,330 --> 00:00:59,170
He and I will talk about the classification based on that mode of operation under this inverter could

8
00:00:59,170 --> 00:01:03,270
be classified into a silly old category.

9
00:01:04,520 --> 00:01:17,020
Let's start with the stand alone inverter system that load inverter in this case ZBB system is a stand

10
00:01:17,020 --> 00:01:23,140
idle that loop can only depend on the DV system for bar.

11
00:01:23,600 --> 00:01:31,990
So Zain Verjee resists up light DC power tools and Newt has to be appear as the boldest source with

12
00:01:32,500 --> 00:01:44,840
a sensible voltage and the frequency supplying power to any three volt E C or one hundred then then

13
00:01:44,930 --> 00:01:52,740
volt E C or as if their voltage is standard as a location.

14
00:01:53,910 --> 00:02:00,020
So the second type is connected inverter.

15
00:02:00,300 --> 00:02:10,620
In this case z v v system is grid connected means the loop can depend on z v v system as well as a great

16
00:02:10,620 --> 00:02:11,710
for power.

17
00:02:11,840 --> 00:02:23,130
Zero is it any sea change between a grid as inverter and Xenu mean then vertical latches on to the correct

18
00:02:23,280 --> 00:02:25,160
frequency and voltage.

19
00:02:25,200 --> 00:02:31,290
Zain Verjee is the main task is to only bomb power into the grid.

20
00:02:31,860 --> 00:02:37,970
So then there are those that supply AC power to say grid as a carbon source.

21
00:02:38,010 --> 00:02:39,660
Why in the room.

22
00:02:39,720 --> 00:02:48,630
Obstacles on hold the source ends the system is fully felt by the grid zealous type is hybrid TV system

23
00:02:49,070 --> 00:02:50,570
like this one.

24
00:02:51,180 --> 00:02:58,100
This configuration are much more ZBB system is capable of all.

25
00:02:58,360 --> 00:03:07,870
If there is then an old system with better storage or get it connected more zip in vertical play a critical

26
00:03:08,080 --> 00:03:15,960
role as it has in its sorcery hardware implementation to work in is a mode based on the operating condition.

27
00:03:17,510 --> 00:03:26,420
As it can operate in the stand alone mode the grid is disconnected as the system might catch up to some

28
00:03:26,420 --> 00:03:32,970
special backup loop within inverter behavior as easy voltage source.

29
00:03:33,320 --> 00:03:44,710
Or it can operate in Garret connected mode at which the inverter behave as an easy target source.

30
00:03:44,710 --> 00:03:52,680
This buying model inverters as is usually more expensive and are less use of it.

31
00:03:52,780 --> 00:04:01,180
There can be four different category under this classification first one is central inverter which are

32
00:04:01,180 --> 00:04:13,810
usually around several to want to one hundred megawatt range second type is more the inverter or micro

33
00:04:13,820 --> 00:04:22,830
inverter typically rated between 50 to 500 Meg given what the string inverter typically rated at around

34
00:04:22,830 --> 00:04:24,340
500.

35
00:04:24,420 --> 00:04:36,620
What do I feel you key to what a string is nothing but a number of TV module connected in series mastering

36
00:04:36,660 --> 00:04:42,470
inverters typically rated around 1 to 1 to 10 kilowatts range.

37
00:04:42,470 --> 00:04:47,290
This is started the way central inverter central inverter.

38
00:04:47,360 --> 00:04:55,960
This is the most to throw an additional inverter to bullish use as seen in the disfigure symbol implementation

39
00:04:56,000 --> 00:05:07,530
with while center in Merthyr catering to all the b v module is that the easiest the main problem of

40
00:05:07,530 --> 00:05:08,800
this style.

41
00:05:08,970 --> 00:05:12,170
It can do work with any BBT to.

42
00:05:12,330 --> 00:05:21,690
The second type is my calling inverted let's look as a micro inverter or module level inverted as the

43
00:05:21,700 --> 00:05:30,430
name suggests it should hold you has its all inversely with N in BBT Dragon.

44
00:05:30,700 --> 00:05:41,900
So as it normally is more efficient to partial shading effect as compared to central invert the micro

45
00:05:41,900 --> 00:05:51,030
in terms of providing the highest system flexibility since the extending size of the system under a

46
00:05:51,040 --> 00:05:53,060
system ology is far simpler.

47
00:05:53,110 --> 00:06:02,980
As a DC While calls are greatly reduced however the investment as the man Thomas calls tend to increase

48
00:06:03,290 --> 00:06:04,480
especially.

49
00:06:04,670 --> 00:06:06,230
It was a cross to bear.

50
00:06:06,390 --> 00:06:14,410
While unconfirmed said of thought it is strange in Perth that we have the string inverted commas which

51
00:06:14,410 --> 00:06:22,900
you seek to strike a balance between Zed build your level inverter and the central inverter to abolishes

52
00:06:24,610 --> 00:06:29,390
sustaining the inverse of topology is more efficient to mismatch.

53
00:06:29,390 --> 00:06:37,730
Zen is the center of invert because it's just string is independently operated and it's all MBP and

54
00:06:37,750 --> 00:06:46,280
broods use a higher energy yield is strength inverter are a smaller Zen and Zen central inverse however

55
00:06:46,280 --> 00:06:48,860
Zen implementation is more complex.

56
00:06:48,860 --> 00:06:53,240
Zen Zen module embarked also zap partial shielding.

57
00:06:53,370 --> 00:07:02,020
When have agreed the influence of this trend converts to bullish lifestyle is modest today to convert

58
00:07:03,190 --> 00:07:11,880
this concept seek to combine the higher energy year of string and with the lower cost of central input

59
00:07:11,990 --> 00:07:22,980
as each of this string is Breitbart processed using the low power DC DC converter it just think has

60
00:07:22,980 --> 00:07:34,260
its own MBP drug implemented alongside the DC DC convert all the second part out order connected sudo

61
00:07:34,330 --> 00:07:44,770
DC bus to the DC AC inverter with an assertive about range only and use the link with DC DC converter

62
00:07:45,100 --> 00:07:49,770
has to be improved to expand the system size.

63
00:07:49,810 --> 00:07:55,080
We now have an overview about the solar inverter and zip technology.

64
00:07:55,240 --> 00:08:02,080
Of course this choice of Zee used to policy for the implementation will depend entirely on the assessed

65
00:08:02,200 --> 00:08:05,820
needs or size or even your system budget.

66
00:08:05,890 --> 00:08:10,870
But in general why choosing any inverter for your b v system.

67
00:08:10,870 --> 00:08:14,970
What are the requirements for both solar inverters.

68
00:08:16,770 --> 00:08:23,970
There are several characteristics dated from those solar inverter furnace then.

69
00:08:23,970 --> 00:08:32,760
Furthermore most of the more efficient typically efficiencies or is the range of between 95 percent

70
00:08:32,790 --> 00:08:35,290
to 99 percent.

71
00:08:36,120 --> 00:08:42,860
Second thing then versus are expected to have a very low harmonic content.

72
00:08:43,980 --> 00:08:54,380
Also like comes Icelandic refers to the situation in which the inverter in a great tie and still continue

73
00:08:54,380 --> 00:08:56,480
to power the system.

74
00:08:56,480 --> 00:09:03,370
Even zero support from the grid operator has been restricted due to safety issues.

75
00:09:03,380 --> 00:09:10,650
Icelandic will need to be prevent last thing depending on the tablet.

76
00:09:11,720 --> 00:09:19,640
It is expected that the inverter had an built in EBV tracker.

77
00:09:19,860 --> 00:09:31,460
Now we already summarize that we need more components to bend the BBC solar system such as battery solar

78
00:09:31,460 --> 00:09:33,540
charger inverters.

79
00:09:33,710 --> 00:09:35,280
It is a make a section.

80
00:09:35,330 --> 00:09:45,350
We are going to connect all this together to better for the types of V V systems and in the last section

81
00:09:45,680 --> 00:09:52,820
we are going to size each component of this component and the NS A last lecture.

82
00:09:52,820 --> 00:10:01,370
We are going to size each component of those component according a given loop so see you in the next

83
00:10:01,370 --> 00:10:10,560
lecture or you will be able to understand the types of b v system see you by.
