Huawei SUN2000-10KTL inverter or Fronius Symo 10.0-3-M which one to choose?

Hello - I have the opportunity to buy the entire 10 kW PV system in good money, i.e. about PLN 40,000. the company offered me a Huawei Sun 2000 10Ktl waveform
I have always thought about Fronius - my question is whether Huawei is worth considering or staying with Fronius.
I am asking for help in making a decision.

Stay with Fronius. No Chinese. And what panels and what power do they propose, or maybe

Q cells 325 Duo

They can be ok, but 40,000 for 10K is a lot.
counting Bruk-bet panels at 10k, you pay a maximum of 18,000 gross, an inverter about PLN 9,500.
also a lot, because Elnix 12kW is 4200 PLN.
But OK, as Fronius is less than PLN 27500, installation is about PLN 3000, so - where do such costs come from PLN 40,000?

Ask the company for a detailed cost estimate of individual elements of the installation and you will be able to compare prices.

I do not know - maybe the other things of the mounting system + cables and mounting make the difference - but I do not know how much should be for such a system, so now I was a bit curious about why such a difference.

4,000 for 1 kWp is the normal price for these components with assembly. Nobody will install 10 kW of panels for free.

Added after 2 [minutes]:

Stay with Fronius.

These are not bad inverters. Only check if a software update is available. I still have Android 4.4 KitKat, this is a drama, instead of reading online parameters, I have reading every half a day on teletext. As you have bought the whole with reasonable money, there is no need to save on chinchin and although you should buy a decent inverter, I recommend Siemens, Samsung.

I have a Chinese and he is 5 years old. And he is more efficient than fronius, I have 2 knocks in the installation, the Chinese are not bad, they improved the technology.

Buddy prose, I will not agree with you. Take fitness measurements and Fronius beats the Chinese.

In my experience, it all beats chniczki. Get yourself a random pyrometer and measure it. No Chinese will assemble it to you like in the west, their certificates and warranty do not correspond to reality at all. In addition, a good look at the situation of Huaweia in Poland and possible penalties and the withdrawal of the company from Poland after the last action that spies. So you don't stay on the ice without a guarantee. In addition, your data may be used and used without your consent, for example, for a future attack on energy independence in Poland. Hence, it is worth supporting our domestic business, you buy in Poland and support the economy. best regards

I will add my three cents about inverters ...
I started in 2014 with the Aurora 3600 and by 2017 I had 10 inverters, I had: Power-one, Saj, Afore, Froniusa, Growatt etc. etc ...
I had them to repair, some, I took apart almost everyone and you know what, there is nothing better than SMA, somehow the elements and their assembly are book-like, the worst were Chinese Afore, Every etc., soldered like a gutter soldering iron ...
I am also surprised by the popularity of Fronius, the interior of the d ** y does not stop and some technical solutions are downright stupid in these inverters, but one likes butter, the other margarine ...
I only recognize SMA and I know that if I have SMA inverters, they will still work after 30 years, as it is visible at auctions that their 30-year-old inverters are still operational ...
As for Polish production, at the price alone, you can expect the interior of the inverter in the lowest, cheapest quality ...

It is a pity that Sma has recently moved most of its production to China. Now I have the impression that it will take several years for me to trust the brand. Unless they sell at Chinese prices, that's fine.

And here, unfortunately, I agree with you, recently SMA is no longer SMA Germany, which was so far :(

So maybe instead of Fronius and Huawey, for example, go to Solar Edge and an intelligent power management system - a total price from PLN 7,000? what do you think worth

You can try SolarEdge with it, it is an Israeli invention, the inverter itself does not have MPPT built-in and each panel must have its own Optimizer, it is important that you buy a set with panel optimaizers and not the inverter itself ...

I know - the set costs about PLN 10,000, but I am offered 14 kW and Q cells 325 W duo panels. Do you think this is a good option? Surplus for domestic hot water.

I don't know, I didn't have this inverter in my hands, I know that in the west they put them on en masse, and how long it will last, how it is built and what is hard for me to say ...

Normal warranty of 12 years can be extended to 20

Rather, the basis for DHW and CO, because it is a pity to give energy for free to operators in accordance with the PIS and RES Act. And another forum -
We have a simple formula X * 0.8 = Z + Y where the energy given to the operator indicated by the numerator is X and Z is the energy consumed by the user indicated by the numerator. X * 0.8 -> this is the energy that the user can receive from the operator and it may be that this value is greater than his demand and we get a surplus of energy, i.e. our Y. Can a RES user sell this energy and at what price? Can he keep it with the operator as in a bank for the following years? NO Pursuant to the RES Act of June 22, 2016, paragraph 4.11 stipulates that the surplus is at the seller's disposal and is not subject to sale. According to the explanations of the Minister of Energy, surplus energy is not sold or stored! From the point of view of installers and RES distributor, it is understandable, because the larger the installation, the greater the profit for them, but for the user there is a problem with the surplus Y, which, according to the act, gives the energy operator and the proposed installation larger than 2 KW for free, and this is causes the giving of energy for free. The townspeople will not be happy that they give their energy away for free, and will say it is theft. Many Z demand calculations were made in 2010 in cases where the user had many C or D energy class devices. Now there are replacements for A or even A ++ energy class devices, which means that our Z (demand) decreases, which automatically increases Y A real installation in accordance with the new RES Act PIS is a maximum of 1.5 KW, and with a higher power of the installation, Y is created, a surplus for which nothing is paid.

You know with these guarantees that everyone is so excited that 10, 20 or even 30 years (the Chinese give so much) it is so that today there is a company and in 2 years there is no trace of it, like for example Suntech (a giant producing panels a few years ago a now it practically does not exist) it was the same with Siding on the house in the 90s, 15-20 years of warranty and a few years later the companies did not exist anymore ...

I do not understand why only 1.5 kW, since my consumption is almost 6 kW and I already have everything in LEDs, etc. I plan the surplus for hot water and heating with foil and maybe one day charging an electric car - this is the plan

Again, someone writes nonsense and has not read the current law. These were only plans for the law in 2016, but they have not been entered into.

You never know what will happen in a few years, but you have to believe in something - in 10 years it may not be a PV system anymore, but some space technology will supply us with electricity. 30 years ago, a cable telephone was a miracle of technology, today we keep the data in the cloud - what in 10 years we do not even dream about it.

Then why everyone wants from me from 16,000 to 20,000 for 3 kWp ..? ;-p
I think I have to look for a company that will install it for me for normal money ...

Maybe you have a heavy roof or difficult access to the switchboard? ; P
16 thousand I can understand for 3kW, but not much for 20.

It's not a light, wooden structure like most, but the ceramic tile and fixings are a bit more expensive, but it's a matter of a few hundred, not a few thousand ... ;-p
I noticed that most companies for the installation of these 3 kWp cost from PLN 2,500 upwards and the better the components, the price for the assembly decreases, but the final price increases anyway ... ;-p
Transport also makes me wonder (min. PLN 900 up ...: - /)

The problem with small installations is that the workload is not much less than with a large one. Because you have to pack the equipment,
you have to get there, take care of the security, the roof tile elevator and all the rest of the crap. There is work on the inverter, AC and DC connections
identical. The only difference between a small installation and a larger one is the dozen or so modules with the roof structure more.
Therefore, the higher the power, the cheaper the kilowatt.

Well, a kilowatt is cheaper but why the labor itself is more expensive with cheaper installations ..? After all, there are fewer robots if there are fewer of these panels to be installed, right?

And did you read and understand what I wrote? Because I don't think so.

But still smaller and the price for the assembly itself is bigger ... But these are your words not mine ... I guess you don't understand what I am writing about ... ..)
