I will also write that after entering the inverter options, there is no possibility to change what I am writing about, the same from the web and mobile application level, a massacre, such an underdevelopment / oversight on the part of Huawei.

Where are the inverter options?
The company set up the entire installation for me and from them I only got the login and password for FusionSolar in advance - but I log in here as a user both on the website and in the application and I can't change anything ... I guess I would have to have access to the installer account - and I don't have it and as the fitter told me, I won't get it.
Can I actually only watch the graph and production bars with only access to the user account?
Do all companies do this to prevent access to the installer account?

Go to the inverter and try like this:

1. Log out of FusionSolar
2. Turn off data transmission on your smartphone
3. Find the inverter WiFi network on your smartphone and connect to it (you have the SSID on the side of the inverter)
4. Click in the top right corner of the FusionSolar login screen (three dots)
5. Select "Putting the device into operation"
6. Scan the QR code on the side of the inverter
7 Enter the password: 00000a and you are in the settings.

If the fitter has changed the password to the inverter, you will not do anything if he does not give you the current one, but I do not understand what it means that the fitter restricts access to your property, take him on a rug and talk him out of it.
If he still does not want to cooperate, request the deletion of your account and you will create an installer account and user account yourself.

Let me ask you in this thread, because I can see that only here you get specific answers from competent people.
I have a question about Huawei inverters.
I will assemble the Huawei Sun2000-5KTL-M0 inverter.
The technical parameters for this inverter do not clearly describe the minimum MPPT value of the inverter, i.e. U dc min.
Two values are given:
1) Operating voltage range: 140V - 980V
2) MPP voltage range for full power: 240V - 850V

I mean the inverter voltage parameter for which it is calculated: "Minimum number of modules in the string due to MPPT of the inverter".
From this formula:


If we take the value: 240V for calculations, it turns out that the minimum number of modules in the string is 6.59.
The company, on the other hand, offered me an installation consisting of 12 panels, 6 in each string. So 6 + 6. Is it not enough?
If we take the value: 140V for calculations, it turns out that the minimum number of modules in the string is 3.84. Then the proposed number of modules in a string, i.e. 6 pcs, would be OK.

The starting voltage of your inverter according to the data sheet is 200 V, now calculate how many planned panels should be connected in series to achieve the required value.

Don't spread the same question over "all" renewable energy .

Sorry for repeating the question. But I have editing tomorrow, time is running out for me and I don't know what to do.
Of course, I calculated the minimum number of panels to get the condition of Start-up voltage 200V. It came out: 4.59, so 6 pcs will be OK.
But according to the formula I have given, you should also check the minimum number of panels due to the inverter operating voltage range, and more precisely to the Minimum voltage value.
According to the formula I gave earlier.
And here the opinions differ, some say that I should use 140V, others say 240V.
For 140V, 3.84 panels are enough.
For 240V, as much as 6.59 panels are needed. And here 6 pcs will not be enough.
People who believe that the assumed value of 140V is incorrect support it with, for example, the following statement:

Quote:

"But what will 140V give you when the inverter does not turn on because it will not see 240V?"

Here are my calculations:

The quote is almost correct, because in fact at 140 it will not start, it needs more. 200

Added after 13 [minutes]:

And you do not take into account the opinion of the contractor, after all, he should be sure that the installation will work and have comparable yields to those in the area, and not only work

So, when reading between the lines, I need more than 200, which is exactly at least 240V.

I take into account the contractor's opinion.
Except that he did not mount these panels on Huawei but on Sofar, which inverter has a lower MPPT voltage. So 6+ 6 will work on it.
He said that Huawei "should" take off. He wasn't making calculations.
However, now I know that Huawei will not start the 6 + 6 panel system.
The starting voltage is supposed to be 200V, but the MPPT voltage is from 240V.
The weaker Huawei 4kW inverter would work without any problems in the 6 + 6 system.

It needs 200 volts to take off, not 240 volts, in the range 240 volts - 850 volts it reaches its best performance.

You have not written what panels Voc have.

I need an area 200 to start working and once it starts it will be at 150
After all, the 5.5 sofar also has the same MPP range

But moment, because it has only now arrived that you have 12 modules, 450 each, which gives 5400W, and with the east-west system, the maximum power from both slopes will be no more than 70%, so calmly the inverter 4 is enough

You have not written what panels Voc have.

The panels are: Jasolar JAM72S20-450 / MR
Parameters under STC conditions
- Open circuit voltage Voc: 49.70
- Voltage at maximum power point Vmp: 41.52
Parameters under NOCT conditions
- Open circuit voltage Voc: 46.90
- Voltage at maximum power point Vmp: 39.19


Using this formula, I calculated that: The maximum module voltage for MPPT conditions is 36.44V, and 6.59 panels are needed to achieve the required 240V.

So it follows that in a 6 + 6 system, they will rarely / or almost never work in the range of 240V - 850V and will not achieve their best performance.
I was even suggested to install 2 additional panels in a 6 + 8 (east-west, because the west part is more south-facing). But this is still 6 panels on one string (East) which will not go into the 240V - 850V range and not achieve its best performance.
So, would a 7 + 7 panel layout be the correct and only correct solution?

Managed to! However, they left the password the default.
But I haven't found too many interesting things here ... I still don't know how I could change the data I see, for example, at https://eu5.fusionsolar.huawei.com
This means, for example, I have a shift by an hour on the chart - now it is 4:00 p.m. and on the chart it gives me production from 5:00 p.m.
Can this page also be accessed with installer permissions?
How is my account linked to the inverter? In the inverter settings, I did not see any ID number or anything similar, so that the data sent from my installation will be linked to the correct account on FusionSolar ...

I do not know what permissions the installer gave you and what you have access to on the web version on the website you provided, for me it is like this:

1. I log in to the website https://eu5.fusionsolar.huawei.com
2. At the top, in the tabs, I have Settings
3.Click on the Settings tab - the System settings / Account settings window should be displayed with your data, user name (partially asterisks), avatar (if you have added one), password (stars), telephone number if you have entered, e-mail address (partially stars)
4. Click in the menu on the left in Manage the installation, give a tick next to the name of your installation and click on modify at the top right, a new window called Modify will appear,
this box will / should contain information, the name of the company that installed the installation, the name of the installation, installation capacity, date of connection and some information such as Installation without social purposes
5. At the top, in the Configuration of the electricity price tab, you can define the price, transmission separately, energy separately
6. In the Other information tab you can set the time zone so that it shows you correctly on the charts.

If you do not have these options after logging in, press the installer to give you the appropriate permissions.

So I should be seeing these settings somewhere here?

On the login screen, select Polish language support, unless you prefer EN.



Then, as indicated in the picture below, select "Settings", then, as I described earlier, if you do not have the "Settings" button, ask the installer for an interview and explain what you mean.

I have a problem logging in to the FusioSolar application.
Please help.
I am an installer, I log in and see both connected installations.
A few days ago I created an "owner" account for one installation. Everything works, the owner can log in.
But today I created another "owner" account for the second installation. Account tested and working. The next time you log in, something happened and when you try to log in, a login or password error message pops up.
Together with the owner, we changed the password (by entering the verification code). password change was successful, login also.
But after a while, it failed to login again.
Repeated attempts by the owner and my installer account to change the password result in a strange message.
"The system is not licensed. Please submit and activate the license."
What's the matter, what license, where to upload and activate it?

A strange situation, because I assigned the same installation to a different owner's account, everything works and it is visible.
I can see and enter the options of the second installation in the same way.

Please help.

Everything is clear
After logging in, I am immediately on the page with the preview of my installation and in the tabs I do not have the settings, only "Kiosk view"


And today I clicked in the tabs on "Home" and the settings appeared (which I had not noticed before because I rarely opened the home page)
So thank you for your help and guidance to solve the problem :D

I also have a question - since I can log in directly to the inverter with the FusionSolar application and I have access to its settings, can I create my installer account and create a new owner as an installer, etc.?
Will this somehow affect the current installer account that the company that set up for me has - for example, will it delete them or maybe there may be two installers for one inverter?

I don't know if you meant it, but to log into the inverter you use the FusionHome application directly (you only need to be connected after that with the built-in wifi) and if they haven't changed your default passwords, you can log in as an administrator without creating any additional account.

Yes, they didn't change their passwords and I can log in like this.
However, I have to stand next to the inverter then. And I would like to see what options my installer account gives me.
It seems to me that they can be large - for example you can see it here: https://youtu.be/5EnFklPXbNQ?t=75

Use the Huawei configurator - https://eu.smartdesign.huawei.com:31943
Create an account and create your installation with a specific inverter and panels. If your panel model is not available in the database (and it probably does not exist), you can manually enter its parameters and add it to the database. The configurator will tell you if everything is fastened correctly.

You won't do this for two reasons:

1. The serial number of your inverter is already in the system and you will not create a second Installer and then User account for this inverter.
2. The e-mail address is already in the system, you will not create a new e-mail either because of the above

The only option is to delete all your installation data from the Huawei system / cloud and a new registration, but I do not know if it is possible.

I duplicate my question because I'm afraid it will go missing after more posts and the owner is pushing me.

The owner cannot log in. Wrong password. Attempts to change the password result in displaying an incomprehensible message: "The system has no license. Please submit and activate the license".
How to fix it?
One thought occurred to me. Could it be because one login was set to Polish, and another to English? Because I think it happened inadvertently.
Because of that, the system blocked "some license" or something?

Alternatively, how to delete the owner account and create a new one for him. Necessarily to the same e-mail address, because he only has one and does not want another one.
In the options of this owner, I can only see the activation / deactivation of his account. Of course, while I am doing this, e-mails with such information come to his e-mail account.
However, I do not see the option to delete the owner account. Can it be done at all?

I do not know if the only option to solve the problem will not be Huawei's support.

Thank you for your response.
I'll try to act.

By the way, not to write a new post.
For an acting user (because he is asking), what and how to enter in the "Configuration of electricity prices" tab?
in your earlier post you wrote:

rokbok wrote:

I do not see: "transmission" and "energy" only: "on-grid price" and "purchase price ..."

I have a slightly different screen / window



In the Electricity price tab I entered distribution, in the Electricity purchase price tab I entered the energy price, did I do it right, I don't know, there is no explanation anywhere.

I also learned about the possibility of changing the currency name from EUR to PLN and so far it is not possible, but it's just a name.

rokbok wrote:

I am trying to analyze it and harmonize it somehow.
If the applications work on the same principle, they only have a different description of "appropriate-same" windows, then maybe it should be interpreted as follows:
1) Price of supplied energy (with you) = Price on-grid (with me). It means the price of energy / electricity that we give to the grid. That is the price for the surplus we sell. If, of course, such a price is specified e.g. in the contract and appears on the invoice.
2) The purchase price of energy (with you and me). It stands for the total price of electricity / electricity that we take from the grid and it consists of the price of electricity and the payment for distribution services.
How do you think?

It's just that if we do not have a meter (DTSU666-H) installed, does entering these prices show something to us in the application? And does it serve anything?
In the FusionSolar application, I can only see one power output from the inverter (split into load / house and grid / power consumer). The current is either produced by the inverter and flows from it to both loads mentioned, or it is not produced by the inverter and is zero. I have never seen the application show that we are taking electricity from an external network.
So, how is the application supposed to know how much we give and how much we download? and somehow illustrate it to us in relation to the prices that we entered in the "Electricity price configuration" tab.
How do you think?

I would consider it in the category of the amount for which the PV installation produced kW, and these are approximate estimates showing + - possible savings, of course, you should also include 20% tribute for energy, according to me it is such an addition to the application as a gadget, not strictly "came - went" settlement.

Hello. For 2 days I have been the owner of a PV installation with the Huawei SUN2000-5KTL inverter. The installer set up an owner account for me on FusionSolar. Today I noticed that on the daily production chart there is a reset at 5:55 pm. As if the daily production was counted from 5:55 pm to 5:55 pm, not from midnight to midnight. Yesterday it was also at 5:55 pm
dzienna pr...dukcja.jpg Download (87.96 kB)
The chart below shows the daily production despite the fact that the result is 0.08kWh, and by about 6 p.m. it grew to the value of about 3.77 kWh.

Even though my total production is 4.16kWh, it shows me from Sep 24 on the monthly chart for these two days. 0.1 kWh and Sep 25 0.08 kWh, which is as if only counting these performance after 5:55 pm.
wykres.jpg Download (35.95 kB)
I suspect that the device is functional and the problem is somewhere in the settings, but from the owner level, I do not have such permissions.
Which of the settings is responsible for this?

If I create an installer account, will I be able to add this inverter to this account, even though it is already added to the account of the person who installed the system.

You won't create, read post # 49

Oki, I think I've already solved the problem. I read and followed the procedure from post # 32. After logging into the inverter, there was immediately a message about the time difference between the phone and the inverter. The time on the inverter was 4:14 on Sep 26. I set the time to the current one. There was an option to set up time synchronization with the NTP server. Set it up?

Set it, you can always undo it.
