Help for my solar battery installation

[Matenjo]

For the regulator with its hybrid inverter that at the start I wanted to go only through the hybrid but believing that this one does not charge my battery I invested in a regulator that I would have liked in the past.

For the batteries I uh the same thought to say that it was rinse voila why I tell to resume but this blow if new because I had bought used, I but the photo of the batteries in attachments.

For its 8mm2 wiring

This morning I went up on the roof with an ampermeter and I found that 1 panel produced nothing so in fact I only have 3 panels of 200wt which work in series, perhaps the cause comes from the so I decided that next weekend I remove all its 200wt and install the 300wt instead with the same assembly (series and parallel) hoping that its the right solution and that finally will work.

Did you use suitable connectors! ??? Waterproof, with good contacts?

[Matenjo]

Yes mc4 and I have control today if his spanks well contact and these from there that I realized that I only had 3 panels that finally work 3 +2 from the other series of 3 so I disconnected the panel which produced nothing and connected the 2 which works in series
I put the 3 in series which works connected to the regulator and its marks me 80vlt and 4 amp and the 2 others which works and which I put in series connected to the inverter is it marks me 52vlt but 0 amps.
My batteries have to charge because there is only 1 line missing so that they are full,
In fact I am annoyed, but battery goes down when I connect a device of more than 300wt.

The regulator also marks me that for the 50,2vlt and 5amp batteries.
I don't know if this is normal? I also don't know if I need to configure my inverter and also use the regulator?
Thanks for trying to help me

Here are the batteries that I intend to invest before Christmas hoping that it will solve my problem

Above all ... You will understand that your situation is a bit of a bag of knots to unravel ... Already that being on site it is not always easy to find ... Then try something remote by the net. .. It is more than uncertain (or not recommended ...)

Yes I doubt it but taking advice from a little bit of everyone helps me.
And having advice is not negligible.
Because maybe and I hope that she will offer me another configuration with the material I have !!
And also I would like to know how to configure my hybrid inverter? But no one still has that answer unfortunately for me. Because maybe that would solve all these problems.
In any case, thank you all for taking an interest in my installation and trying to understand me.

PS: thank you to izentrop for advising me another forum but I already know it and find to my taste that it is not terrible and far from being better than that.

I fully agree with AD44, even if I understand your impatience given your isolated situation from the network, in my opinion you lack a bit of "methology" in the search for a solution. It would of course be best if someone could advise you on the spot, but it will certainly be difficult to find, except "good soul" that you could perhaps locate on a forum more specialized.

That said, I think the first thing to do, because the panels and batteries are used, is to make sure of their condition. The fact that you discover this morning (if I understood correctly) that one of your 6 panels is HS, it made you waste time and think / try in all directions when it just couldn't work properly on a 3series / 2parallel diagram like the one you described.

Then, but here I am not a specialist and it deserves to be confirmed or denied, I do not think that a diagram with two chargers in parallel (the controller and the "charger" part of the hybrid inverter) can really well function. In other words, you will (in my opinion) have to choose your side! As already said by others, it seems to me that the hybrid inverter is made for that, by only drifting towards the batteries what is not directly consumed in real time during the period of solar production.

Finally, and above all that is the message, do not spend almost 2000 € on batteries before to have managed to make the system work properly, you just risk shooting them faster!

[Matenjo]

Thank you but I would like to spend only on the hybrid inverter but for that I would have to manage to configure it, and its its things that I can not do, and if someone would be how to do and well it would be with pleasure. Because I searched but in vain, I know how to enter the menu but after I do not know what to select.
I found a doc on a solar mppt, almost like mine but in the settings it is not exactly the same, so really the hassle of knowing what good adjustment made.
After its works as I did but impossible to put more than 300wt see 400wt without the batteries go down to almost empty.
So here is prk I think of the drums that do their job more but how do you know?
Thank you

????? Isn't that the one?

No these not this one, thank you for this link but these the same doc that I found too
Its really looks like it but mine has more parameters is only some of the parameters corresponds to the one I have.
