Lessons / Learning Mode

Yes, PV Solar Sim app have a section that you can learn about entire solar system!

Why to learn about solar energy ? Because, let`s say that :

For example

Your inverter can deal with 500 volts and you can use only 3 solar panels ?

Yes! Because is limited by 40 amperes! To solve this, you have to wire all in series!

Or if you don't know this, you will put more panels and in the best case, the system will not work!

Or it will work if there is not enough sun when you put it into operation and when the sun comes, the system will overload your inverter and in the best case the fuse will act and the system will automatically shut down, or it will be irreparably damaged.

In addition, there is a very high risk of fire.

So, for this reason it is very important to learn at least the basics.

What and how will you learn?

I chose a method that seems easy to me, like a kind of simulator and at the same time you can learn.

#### Visual PV Solar Sim

On the left side you can see what one of the lessons actually looks like.

###### What is he asking us?

We have to build a 2000w system

- 1. The first time, we have to look at the details of the inverter to see what limits it has?
- 2. The first time let's put batteries. They are at the bottom of the image, at point 3 and 4.
- 3. Point 3 is in parallel, which means that we will have a current of 12 volts and 400 Ah Point 4 is in series, where we will have 24 volts and only 200 Ah.

###### What do we choose?

If the inverter works on 24 volts, normally we will choose point 4, yes?

- 4. Up at the panels we have 2 options, point 1 and 2 yes?

At point 1, we see that 6 panels of 500 watts and 33 - 36 volts each are connected and at point 2 there are only 4 panels, also connected in parallel. What will we choose here ?

If the inverter supports a maximum of 2000 watts?

Point 2, of course !

To use 6 solar panels, we will have an inverter that supports 3000 w yes?

Because 500w multiplied by 4 is 2000 and 500 multiplied by 6 is 3000 yes?

Was I clear enough?

# Next, Lesson

On the right side, we see a scheme almost similar to the one above, right?

Is not!

It is so different that it can break the system if you choose wrongly! Let me explain! At point 1 we have 6 photovoltaic panels connected in parallel, of 500w each, that is, 6 multiplied by 500 is 3000w, so the inverter in the example above can handle it!

At point 2, we have 4 photovoltaic panels connected in parallel, so to cut it short, we have 2000 watts!

### Can we use them with this inverter or not?

We can, of course we can.

Why ?

Because the 3000 watts are within the parameters and the voltage is also within the parameters.

One panel produces 33 - 36 volts and the inverter supports from 12 to 160 volts, and the 60 amps are in the graph, so we are good.

Point 3 is represented by 4 batteries connected in parallel, this means that the voltage will not increase, 12 volts will remain, so they are in the graph.

Point 4 will destroy our inverter or the fuse will blow and it will not work, because it is designed to work only with 12 volts, and there will be 24 volts.

This was one of the lessons, you can see more below, or you can even install the application on your phone.
