6 KWp photovoltaic installation - diagram and connection method

Hello,
Due to the recent favorable conditions (my electricity program, tax deductions), I decided to install a photovoltaic installation. As I have limited funds, basic knowledge of electricity and I like to tinker sometimes - I decided to do it myself. I have purchased a ready-made kit:
22 Just Solar 285W panels
Growatt 3-phase 6000W inverter
wiring with protections

The assumptions are that there will be two strings of 11 panels each (so far I have managed to mount one on the roof).
One string is facing south, the other string is facing south-west.

Now it's time to connect everything to the electricity grid and therefore I have a few questions:
1. I have made a diagram - is it correct? Is such a scheme enough to make a notification to PGE?

- The switch in the diagram is built into the inverter, I think it could use one more just behind the panels, but is it necessary?
- Overvoltage limiter, probably should be additionally of type 1- Can I add it later and does it have to be included in the diagram when submitting?
2. I have SEP qualifications up to 1kV, are such permissions enough to report to PGE? I have already read a few posts on this subject and opinions are contradictory.

No protection on DC side.
PGE also requires a D.

It doesn't have to be a surge arrester, you lack overcurrent protection on both sides. The diagram should also include a ZE energy meter.
Operation permits are sufficient for PGE. This is also the information in the form.

Application form, point 7.3 "I am authorized to perform the micro-installations covered by this application:
......... or a valid qualification certificate authorizing the company to operate equipment, installations and networks No. .... "
In my opinion, SEP is enough.

There is no such thing as a Qualification Certificate.
SEP is the Association of Polish Electrical Engineers and other organizations can also issue a Qualification Certificate
3.1.11. Don't post messages that are misleading

Depending on the branch, some also require supervision.

I guess every branch has the same rules

Still the question is what security is missing on the DC side?

http://www.jeanmueller.pl/?s=11&id_grp=250&id_pck=20 You have ready schematics

On the DC side there should be 10x38 fuses in the bases.

ZE does not care what you have on the DC side, e.g. in microinverters there are no fuses on the DC side, it has to be only overcurrent on the AC side. But of course you should put fuses and a good SPD on the DC and AC sides for your own safety and peace of mind

Dear Mr. Moderator.
I am not misleading anyone, I just quoted APPLICATION / INSTALLATION DOCUMENT CONNECTION OF MICRO INSTALLATION TO PGE ELECTROMAGNETIC NETWORK

Moderated By Topolski Mirosław:

Is this a quote from PGE?
...... In my opinion, SEP is enough .....

I would also like to add that in order to obtain a subsidy from the "my current" program, you also need an invoice for the installation service. Without this, the application will be rejected.
Link

It will not be rejected if it has the appropriate permissions and is the owner of the installation, it can be installed by itself.
Regulations have changed since mid-October.

Some time ago I talked about this with a consultant from NFOSIGW (they are responsible for My Electricity) and when asked if an invoice for the assembly is needed, I got the answer that it is enough to have receipts for the purchase of elements used to make the installation, which must reflect the facts in the event of a possible inspection . Looking at it from a different perspective, if it was not possible to make the installation on your own, the only goal of the "My Electricity" program would be to enrich installers / sellers of solar systems. Although the link in Junkerp's post is puzzling ...

I recommend this text: https://globenergia.pl/uwaga-zmiana-regulktur...L6lHT8BFGMBJwz0fLjIJEEdIvCaxHcQIj8ucEIiAuuLHQ
I called the NFEP 2 weeks ago and received information that without an invoice for assembly, they reject the application from the machine. And here is such positive information.

Hello.

I have a question if someone could submit a diagram to report the installation to ENEA. I have DC and AC protection, a SOFAR 11KTL-X inverter and 34 Bluesun 290W panels, a cable from a 4x16 inverter to a box with a meter and a pylon by the panels. If someone could do such a schematic I would be very grateful as I have never dealt with schematic programs. If this is a problem, please let me know about the cost of such a scheme in PW or send an email to spal84(_at_)gmail.com

Hi. Could someone who has already dealt with the connection of a PV installation, advise me if this scheme will be passed on to Energa?

Gentlemen, can the earthing of individual elements of the photovoltaic micro-installation be connected to the existing earthing of the installation in the house instead of the hammered earthing? The existing earthing is connected to the PGE network.

As for the self-installation and "My current", on the website of the National Fund for Environmental Protection and Water Management, there is a declaration for self-installers in the downloadable documents, which must be attached to the documentation, a nice lady from the National Fund for Environmental Protection and Water Management who deals with the "My current" program told me on the phone that it would be enough.

Hello
I would like to ask about the Just Solar 285W panels that you have purchased, please give me some information.

Hello,

I do not compare with panels from other companies, but out of 22 panels that have reached me, only one had a defect that caught my eye - one guide path was torn, I was afraid that the panel would not work properly, but after measuring the parameters, it turned out that it does not differ from the others. In general, I can not fault anything, workmanship ok, the actual parameters are the same as those given on the nameplate.

Hello, thank you for your answer. I would like to ask you more, you imported these panels or bought them in Poland. Can I ask for some purchasing information?

I bought everything needed for the photovoltaic installation in this store www.solarne.info. The price was not too bad, so you could buy some items cheaper elsewhere, but if you add shipping costs from several stores, it is the same and more confusion is made. The order was carried out without any problems, in addition, the staff knows their stuff because if I had a few questions, they were able to answer.

Thank you for your answer.
I, too, would like to set up an installation, so any comments are very valuable to me.

He already has an offer from them. About 18k PLN. Growatt inverter. They even answer stupid questions very bravely.

I bought them and they received them without any problems. In a few days I am submitting the papers to PGE.

Post No: 1, 8, 17, and Google also does not bite https://www.google.com/search?q=schemat+mikro...dXDEcQ_AUoAXoECAwQAw&biw=1920&bih=969#imgrc=_

I reply to PW " Hi,
I wanted to ask you about this diagram that you showed for the energy of PV installations.
Did they accept him and make decisions about joining? Did you have to change something? Is this form ok?
And an additional question, how did you draw this schema? Any convenient tool?

Thanks
Paul "

I am attaching the current diagram, which I have submitted to Energa Operator and which has been approved and issued the permit.
Drawn in AutoCad.
Important note. It is best to call energy or look at the contract and the data of the object on the application as well as in the drawing should be identical to the contract. Even if it is not covered with reality.



I additionally attach a file in the .dwg version

After the required scheme by energe for the purpose of admitting the installation to the network and consequently replacing the meter with a 2-way one, what more do you need?
In particular, my question relates to the design of the installation.
Because to mount you need to have Sep Eid or Udt Oze or building qualifications for installation.

However, designing requires building qualifications or a permit.
What does this project look like? Is it just this diagram or maybe a wider document?

Wanting to outsource the design part, how much does such a service currently cost?
Assembly on its own considering the possession of sep.

Thanks and regards

Up to 50kW, it is a micro installation, without projects, to be submitted a single-line diagram as above and declaration cards for panels and inverter
