Huawei SUN2000 Inverter: WIFI Dongle Connection, Firmware Update & FusionSolar

Seriously, a guy from Enea's BOK said that? It's illegal as far as I know. And the German standard has the same voltages as PL. Czech has higher.

This is generally quite a curiosity for me. Is it that the network is not protected against excessively high voltages? It would be a little reckless to base on the fact that such a Kowalski has a well-positioned inverter. There will always be some Janusz who will raise the value of V.

Does too high voltage in the network mean that the current is supplied in something other than the contract specification?

But what's so terrible about that. A self-respecting Polish photovoltaic company KENO in its online guides tells you to set the Czech standard, and here you are:
https://youtu.be/MY0ark4DDok?t=139

After the update around mid-February this year, the Polish PN standard appeared in the inverter. So there are discussions about setting up others (unless we are using voltage arts ) have become (perhaps?) pointless.
PS. an electrician friend warned that power plants are starting to look more closely at the voltages of customers (especially prosumers) through new meters, and proving in court that the over 253V in the network is the fault of the plant and not the customer - it is digging with the horse ... (but he mentioned that the plant - at least PGE - strictly adheres to the setting of voltage on the hits and does not weed out prosumers by raising the voltage on the taps).
On the other hand, if the inverter detects over 253V and starts to turn off and I have it set on the inverter OK, who is to look for Janusz, who has assembled a mini-farm next door and closed 260V?

I have installations from December on SUN2000-6KTL-M1 and even then there was a Polish standard with soft 140 to choose from. And even if it was not there before, the guides could recommend the DE standard, but KENO recommends the Czech standard.

And do the new bidirectional digital meters do not have information about the vlottery at the entrance from the prosumer? If so, the plant can remotely control them, just like now it looks like feeding energy consumption to the Tauron eLumer system. It seems to me that EVs should have options to monitor such parameters and react when they are exceeded. It really shouldn't be difficult. They're all on the cable

Well: a quote from the description on the website of the manufacturer of Gama meters (i.e. meters used, among others, by PGE): "Power quality monitoring (overvoltage, voltage drop, overcurrent)"
So structurally they can, and do plants use this functionality ...

Are you running Fusion Solar? I have had a problem logging in since yesterday. It works without a problem via www. Thanks for the answer

It can get stuck at times, but it works. Recently, in the web version, I had a problem with automatic logging out despite the option not to log out. Today, it probably returned to normal because I was not logged out of the machine.

Hi,

Anyone have any idea how to restore default settings without connecting via Fusion Solar applications in SUN2000MA?

Well, I have a problem that everything flickered nicely until I installed the update with tip 140.
The inverter broadcasts the SSID SUN2000 *, you can connect to WiFi nicely, but it is impossible to enter the inverter settings for China.
The network is there - no access. It doesn't search for the device at all.
Neither on iOS nor on Android he wants to twitch.
Update was successful, no rainbow of LEDs, energy is being produced.
Scanning the QR code or searching for the device manually has no effect.
Turning AC DC off, on and off also has no effect.
Dongle can't be found either, but in this case it doesn't even show the net.
I tried to connect to the inverter via usb, but it is also impossible to connect to it.
I have run out of ideas and I have no idea how to restore this device to factory settings, other method than connecting to the inverter and restoring them through applications.
Please throw at least a grain of information on how to deal with it.

Maybe try to change the firmware to 141 or earlier 139 through the fusionsolar website. Maybe it'll help.

The topic of the Fusion Solar application will also be explored. It hasn't worked for me for several days. When trying to log in, it enters the login and password and the message the user does not exist or the password is incorrect. Via the website without any problems. I've already tried uninstalling and reinstalling the app to no avail. Anyone met with such a case? Thanks in advance for your help

Could you please provide the * 139 version? I do not have access to files and I read somewhere that someone had a similar problem after switching to 140.

I had a similar problem and the only thing that could be done was to change the firmware version via the fusion solar portal, but you do not enter the firmware file there, but choose from the list so the firmware file itself is not needed for anything.

Unfortunately, I do not have version 139. I am sitting on version 132 myself and somehow I can't get myself ready for the update but I have to finally do it because I have a strange case of drop in temporary production for no apparent reason, which repeats irregularly or maybe updating will help in something.
Do as the previous speaker wrote. Force an update via the web page. You select the type of device to be updated and add the version you want to update from the list.

Hi,

when I had a similar problem, I changed the Fusion Solar website from https://intl.fusionsolar.huawei.com to https://eu5.fusionsolar.huawei.com. This changes on the same page where the user and password fields are.

Unfortunately, in my case it will not be possible. The inverter is not delegated.

And I have a problem with communication, the message "Incorrect communication between the system and devices" appeared, I will add that it has a repeater inserted on the network cable from the inverter. I tried to login directly to the inverter as an installer and asked for software updates and I did. I set up the Wi-Fi connection, because the weak signal from the router is there and it caught, i.e. all messages are correct, only that on FUSIONSOLAR you can not see any production - everything is zero and there is no animation giving the current to the network. After logging in, the yields can be seen directly. What may be the problem?

I just come back from the Huawei service. After logging in to the inverter, production is ok, but everything is still in the application itself. Upgrading the inverter to 141, dongle to 130. And nothing. Communication with the router ok. But the problem is not solved. Remaining dongle replacement

On the application login screen, select the 3 dots in the upper right corner (the phone cannot be connected to the network, the mobile is turned off) only then the option to put the device into operation will appear. QR scan etc ..

Gentlemen, I have such a problem. I have two inverters mounted next to each other. One is SUN2000-10KTL-M0 (software version: V100R001C00SPC140), the other is SUN2000-6KTL-M1 (software version: V100R001C00SPC140). The problem is that the 6KTL inverter won't connect to the "management center". I tried different addresses (given in this topic, but to no avail). What is strange? that the 10KTL inverter - located next to the 6KTL works flawlessly. Both are connected to the same wi-fi network. What could be the cause, how can I fix it?

Have you tried to change the server address to region02eu5.fusionsolar.huawei.com? It helped me.

It is not possible, the inverter is from the Chinese distribution and despite many attempts it was impossible to return it. After upgrading to 140, it is not possible to connect to the inverter at all via apps, but you can connect to the inverter's wifi network.

Attach to the dongle and check if there is any ordinal number there, because something reminds me that there was some one there. On this broken one, try to change it to 2.

I have the eu5 server set as the main one .. only what helped was the replacement of the dongle ... I don't know whether the installer who performed the installation a few days ago did not damage the dongle somewhere, but the dongle communicated with the client's network on fusion installation on fusion visible as connected but zero indicated after DC and AC side ..

Where to find this order list? I understand that I need to log in as installer and somewhere in the communication settings?

Edit: The inverter has updated to the SPC141 software version and started communicating correctly with the management system.

Hey, does anyone know why after FusionSolar has downloaded the current software (v140), I get a message that the update has been delayed?

Welcome

Measurement with the inverter turned off shows 279 V, and when the inverter is turned on, the measurement is 1.3V

Hello, was it possible to solve the problem with too low voltage after connecting the inverter? I have the same problem.

I don't have an installer account: /
Unfortunately, overnight the firmware has updated itself to v140, and I have the same problem as others, i.e. I cannot connect to the inverter to change the settings, and now it does not send me any data to the Home Assistant.

Is there any option to solve this problem? : /

Hello
In the Fusion Solar application, for several weeks it has not shown me the current production of electricity by PV panels (currently the value is zero kW) as in the picture, the so-called dot was also moving. electric charge with distribution to household appliances and to electricity fed into the network.
What is the reason it is not showing it to me now and how can I change it ???
I would also like to see on this graphic what value is taken by home appliances and how much goes into the network.
Thank you in advance for your help.

You will not see how much goes into the network in this graphic, but you can see it in the "Statistics" tab, at the bottom next to "Overview", but you would have to install the DDTU666-H counter for 3F installations or DDSU666-H for 1F installations.

As for the zero indications, try uninstalling Fusion Solar and reinstalling, maybe there is an error in the app.
