Hi
I am thinking of setting up a 5kw installation with the possibility of later expansion. I was offered 3 sets (2 standard 5kW and one with the possibility of expansion)
1. Afore 5kW + 16pcs Ja Solar 325W inverter for PLN 25300
2. Afore 5kW + 16pcs Sharp (NU-AC310) 310W inverter for the price of PLN 24900
3. Fronius 8.2-3 + 16 pcs Sharp (NU-AC310) 310 W for the price of 28 600 PLN
What do you think are these good prices? I want it to be correct (sometimes investing too much in the best components alone is unprofitable). I am asking for advice on what to look for when guarding the team, what security, etc., should you divide it into two strings or do it on one strings? (the roof of the farm building is a simple gable, 13mx4.5m, there is only a chimney in 1/3 of the roof (installation from the south).
Thanks in advance for your answer

Take Huawei - and I have it myself and it's great, 1500 cheaper than Fronius and no fan. Its temperature is 36-39 degrees Celsius. I already have an operational 1850 kWh from mid-February with a 9 kW panel

I bet on the diode because it is the weakest link here

Not necessarily, I bought a used IBM 230W quite a long time ago and all of them had breaks on the tape connections in the can (8), and the LEDs were good.

one broke after 3 years

Or maybe it can still be repaired by yourself ..?

Probably a diode or a break on some connection because 1/3 of the panel does not work.
But this is just an example of how the long-term guarantees that everyone so praises work.

I bet on the diode because it is the weakest link here (repair as simple as the sun - you can probably fix it yourself ... )

Unless the entire can is flooded with an undefined mass (plastic) that you want to remove on average.

gaps on the tape joints in the can

This also goes to do ... ;-)

It can be hard, but also to be done in my opinion ... You can heat up and pick out how much acetone you need to use (before that, I would advise you to protect the back of the panel if it is not made of glass ...)

Well, I did, soldered and have been producing for four years.

When it comes to lab performance, Huawei wins.

Huawei:


Fronius:


When it comes to guarantees, you can extend Fronius up to 20 years, Huawei max up to 10 years.

From my experience and experience, I can add dozens of inverters, SMA is without fail and the best made of all.
But this is my opinion and experience.

As for me, these charts do not show that any one is better than the other because they are identical ...

Do you have a friendly team that will not wear out - I want to set up a 9.9 kW set on the ground?

On FB Photovoltaic, ask, this is not the forum

Only recently have I finally removed Facebook permanently and now I have to assume again to find out, no one can just write?

Maybe it will be easier if you write where you are from.

This is the name of the company that installed 4.44kWp on the Longi 370Wp half-cut with this Huawei SUN200 4ktl inverter at the most competitive price ...

Does anyone know if this Huawei SUN2000 has Modbus on board?
Manual talks about M-Bus and RS485. I can't find any communication details or info about the RS-485.

Has a modbus. On the manufacturer's website it is described in detail. Link It also has modbus TCP for wireless communication.

Thanks a lot, I couldn't find such a document.

And what does it do ..?

Access to various information from the inverter. Take a look at the instructions from the link and you will see what can be read in real time. I use it to integrate with Home Assistant. And I dump statistics into the database.

4,000 for 1 kWp is the normal price for these components with assembly

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 ...

Certain elements of the installation are fixed: switchgear, AC and DC protection, cables, pin or ring earth electrode, earth wire, mounting structure for 3kW and 10kW is not a proportional price for kWp, the 3kW Fronius inverter costs about PLN 5500, and more than 3 times the larger 10kW Fronius costs only PLN 9,500 - it is also not proportional to the price. Therefore, companies will not come for the same price per kWp to install up to 5kWp and up to 10kWp. Remember that each installation has an official final invoice and they pay 17% income tax on their earnings (because the investor deducts the official amount from the invoice as part of the thermomodernization relief from the tax, of course reduced by the subsidy of PLN 5,000 from My Electricity). In addition, correct installation on the roof is the basis, if they screw up something, it will not take a roofer to climb on the roof and fix it. As in any service industry, it is easy to count how much money the contractor earns, because for us, income = income, and this is not the same, there are always costs that we investors do not want to think about, and contractors must.

I would choose Fronius for 100% - my experience shows that it is the least emergency.
Huawei - it's also very good - BUT - has problems: for example, it is impossible to reset the inverter I currently have 5 Huawei inverters in which another company has set a password - the customer has changed the WiFi name - and we can NOT reset and reset the communication of the inverters. The described procedure does not help - Huawei responded with support, YES, WE KNOW and we are working on it, please try again one time after two hours of trying, I failed.
I have had no problems with the Fronius for 7 years, even the old IG series still has support and works great.
Sharp panels - good, very good panels.

PRICE - the smaller the installation, the more expensive - costs such as employee wages, travel, accommodation, equipment depreciation are fixed. When we install 3 - 4 kWp on the tiles, we can install 10 kWp on the trapezoid
Calculate how the fixed costs are distributed over the price of 1 kWp :)

The average price per kWp for installations up to 10 kWp is from 4,000 to even 6,000 PLN - (I assume decent components, an experienced, decent team, making a set of measurements), while 30 panels on a low, not too steep trapezoid with a simple connection will be much cheaper than 12 panels per 3-storey house, covered with tiles (each screwed), with an angle of 50 degrees and the need to make your own grounding.

So the price of PLN 6,000 for 3 kWp should come as no surprise.

I recommend Ekofachowców

Companies like Ekofachowcy are companies that are intermediaries with a shiny website and traders who (now even from Cyfrowy Polsat) sell photovoltaic installations, then contact local contractors to do everything and finally drink the cream ... You really have to understand, that Photovoltaics is another new construction industry and, just like when installing a roof, it is worth looking for decent local teams to whom there is constant service and warranty access. When we spend PLN 50,000 on the roof, we carefully check the materials (while some Chinese panels are really good, it is really worth adding to the inverter) and we give it to an intermediary who will come in a suit and then I will send a team out of nowhere with a predominance of Ukrainians . The question is how much this intermediary company will exist and where to look for Sp. z o. o. with a share capital of PLN 5,000. Each installation will somehow work, but the point is that it should work optimally and as soon as possible, the energy production will pay for the costs incurred and work flawlessly without extending profitability by adding to investments for repair or replacement, for example, a Chinese inverter or even a top inverter only damaged due to the lack of good overvoltage protections or incorrect earthing (with measurements).
Design and execution errors will not come out in the first year of use, they will come out after a few years, remember that good panels will still produce energy for us for up to 25 years at the level of 80% of their nominal power, but what about the rest of the installation? ...

Hello,
Please help me choose panels and an inverter for 3.3 kW installations. I am a woman with very little news on this subject. I have many offers from companies that differ in terms of products and prices. Each company says their product is the best.

In my opinion, the most interesting offer is:

Jinko panels / Fronius Symo or Huawei inverter.


I might be wrong??
Please help .

Thank you.

Because

How an inverter at home is huawei because fronius has a fan. In addition, Huawei is at least PLN 1000 cheaper.

Thank you for the hint.

The company gives me Huawei or Fronius S falowiniki for the same price - I think it's a good price.

One of the above inverter, plus 10 Jinko 330 panels for PLN 14,000.

Should I choose something else?

I haven't signed the contract yet.

Best regards.

If it is the same price, I recommend Fronius of course.
More experience and quality than Chinese.

Are Jinko panels ok?

This Fronius is at the same price because it is without the datamenager. So without the possibility of viewing everything via the Internet. If Fronius is only M, but it is about PLN 1000 more.
