Welcome, my friend.
I hope you all are agreed to, they are going to learn a very important topic, which is the PV system
connection.
Let's start.
First thing, we are going to start with the upgrade levee system.
The main component of upgrade the system is Zebedee Tunnel.
Boucherie.
And solar charger to control their voltage of the battery, all charging the battery.
And AC inverter or DC to AC converter.
And the easy path.
And for protection, we will need.
D.C. and D.C. fuses, first of all, we are going to connect that, be the panel to that solar charger.
First thing, this little Georgia has a six pence.
First and second one or four, Zebb panel, third and the fourth are for the better in the last two
or four D.C. Luthe.
This, again, to connect this component first thing, we are going to connect the B.V. panel to the.
Solar charger through these fuels like this.
This is a positive terminal of the venom is going to be connected to one end of the fuse and the other
bin is going to be connected to that positive terminal of the terminal in the charge of Madu.
And the negative terminal of Zebedee is going to be directly connected to the negative blow and the
charger like this.
Now, we have connected Zebedee Modu.
Second, saying we are going to do is to connect the battery to the solar charger.
These two.
I'm going to be connected to these other Bence, this.
Now, we have connected Zapater.
The next thing we are going to do is to connect the inverter.
There are two way to connect the inverter in this missile.
First way is to connect the.
Inverter to the positive and negative terminal, these positive and negative terminal.
The second method is to connect the inverter to the battery.
Let's start with the first one.
The first one has a very important disadvantage, which is usually that solar charger, the desired
rating for this, been in the solar charger or 10 percent of the rating current.
So is that solar charger is 100 ember.
So the capacity of this bends are then ampere only.
So the first one is limited to 10 percent of the rating part of that solar charger.
So it has a very bad disadvantage.
So let's go to the next one is we are going to connect the solar inverter to the battery like this.
It's a positive turn them and the negative term.
Now, we have connected that solar inverter or inverter.
Now, we will need to connect this inverter to the AC Bernath.
We are going to connect the line of the inverter to the fuse like this, and the output is going to
be connected to the AC panel and the.
Neutra is going to be connected directly to the AC from.
And if you have a DC lood like this, you only need to connect like this from the solar charger directly.
Now, as you see, this solar panel is directly connected to that solar charger, solar charger has
expen first to offer for that solar panel.
Second to all for the better.
The last two or four D.C. lose, if you want to connect and inverter, you will connect it in parallel
with the battery.
Alexis.
Let's go to the second type of B.V. system, which is on Grid B.V. system.
The main component of Uncrate B.V. System or B.V. panel.
AC inverter or uncrate AC inverter.
Easy find them.
Bidirectional meter.
And for protection, you will need easy and D.C. fuses like this.
First thing, let's start Conexion from the B.V. both.
We are going to connect the positive terminal of the viburnum to suffuse directly like this and the
out of SFUSD is going to be connected to the solar inverter or on grid inverter like this as a negative
term that is going to be connected like this.
Now, the output of inverter is light and neutral.
The line is going to be connected to this AC fuse and the output of fuse is going to be connected to
that.
If watch it is going to supply the easy route as a neutral is going to be connected directly to, is
there enough to supply the absolute.
Now, as you see, we have connected that we've been to the absolute.
Second thing, we will need to connect this terminal also to that bidirectional.
Meter x out of bidirectional meter is going to correct right now, it's a sunny day when the sun exists.
The boat is going from that B.V. module to the AC Dunnam.
Lanxess.
The supplies like this and the extra power from the B.V. bundle will go to the grid like this.
But at Sadaat or in the night, there is no power from Zebley Benim, so we will supply the loot from
the.
Greg, I really like this.
So in the bar to Tuesday.
Good, it is in Boston.
The power flowing from the grid to the ACLU are a negative, so.
You can say the total bill of this and INM is going to be.
Zabar, impulsive, going to great minus the bar.
Coming from the grid to supply the loot.
That's all for today.
Thank you for watching.
I hope I see you in the next lecture.
Goodbye.
