Choosing a MPPT

[elliot]

Hi,
I am wondering about MPPT regulators.
I explain the context:
I currently have a photovoltaic panel whose characteristics are as follows:
Pmpp = 135Wp
Umpp = 18.3V
Uoc = 22.0 V
= Impp = 7.40 A
Isc = 8.56 A

I would like to know if I can take a Mppt sized for 4 panels like the one described above and connect only one for the moment?

Subsidiary question: I started building a vertical wind turbine which I would later like to connect to the Mppt ... are there models with 2 separate inputs?


Thank you in advance for your answers .

Forget the mixed solar-wind regulation: as much want to add salads with carrots.
What are the characteristics of your Mppt regulator, what is the load, do you want to connect in series or in //?

Good evening elephant and thank you for this quick response.

For the characteristics, I don't know anything about it, I'm still looking for it ...
I specify the electricity is not (but then not at all) my strong point, but when you speak of series or in //, I suppose that it concerns the batteries ... and in this case I think that I will do simple and stay on 12v and in this case, it will surely be ... ... I recovered several 12v batteries but given that they are not all of the same capacity, I suppose that excluded the serial connection ..
Suddenly, my first question evolves, namely how to recharge from two sources the same set of batteries?

Thanks again ..

I take note !

Hello.
For 4 panels like the one described above in the posts, 10A will be much too weak.
For an OK sign but not 4.
What do you call 2 sources?

I take note !

Very positive this reaction especially since almost all the commercial sites do not give enough technical information, which sometimes are very complex !!

The ideal for the customer is to be able to consult online before purchasing all the manufacturer's instructions, to avoid any error or misunderstanding, even with user opinions !!

The store page says:
Buffer battery connection or live use

While the pdf specifies that a battery is essential (and that it must even be connected before the solar panel).

Who is right ?

[jpiasecki]

The pdf indicates the use of a battery because it is the main function of this regulator: to recharge a battery by exploiting the maximum power deliverable by the panels.
For direct connection, I do not see any drawback because the regulator will automatically adapt to the load connected to its terminals If it is well designed it will adapt very quickly.
However, it is still preferable to connect it to buffer batteries.
What do others think?

Hard to say...
Without a battery, the regulator may simply not even start.
You have to know how it is designed.

Well if I wrote it in the product sheet is that I had read it somewhere (but there, remember where).

Grid feed-in inverters (SMA brand or other https://www.econologie.com/onduleur-sola ... -4118.html ) are MPPT and without battery, am I wrong?
