    There are also a lot of setting options in fusionsolar for android. There is no "voltage suppression" but there are options for power regulation.

    @bpsw9a I haven't had the settings you showed in a while.
    In Fusion Solar on Android, I select in turn: Installation - Devices - Inverter
    Huawei SUN2000 Inverter: WIFI Dongle Connection, Firmware Update & FusionSolar

    Then I click on the 4 dots in the upper right corner, where I select "Parameter settings" from the list.

    Only 6 parameter items to be changed are shown.

    Maybe in this new version, after update, I can't find the settings you showed. Where to look for it?
    In the SUN2000 application I have all these options. Unfortunately, it is cumbersome to run to the inverter to view them and possibly change them.
    I'd rather do it remotely from anywhere in the FS app like it used to be.

    P.S
    I changed the network code from GER to PL.
    Unfortunately, it did not change anything in the number of options to be set in the FS application. :-(

    Or maybe approach the inverter with the cell and try to connect normally through the internal APek of the inverter and not through the "portal" - maybe then there will be more options ...
    Edit: and I mean the FusionSolar application here, because I also know that it is possible in SUN2000 (and you also wrote).

    @gitpusher I wrote in an earlier post.
    Through the SUN2000 application and connecting to the inverters via the internal Wi-Fi network, I have a lot of configuration options. But it's not convenient.
    I supervise several installations in a family in which I am assigned as Installer. It's hard to drive from house to house.
    I would like to be able to access, even when away from the inverter, via the Fusion Solar app. Just like @bpsw9a , @xszuflax and others.

    Hi,

    I think we misunderstood each other. I have these options in FusionSolar, however, the access itself is carried out through the "Commissioning device" function, which involves direct access to the inverter via its internal WiFi.

    The option itself is available in Power control > Active power control.

    @xszuflax so you approach the inverter and Fusion Solar in the "Commissioning the device" option, you scan its QR code each time to get to the options we are talking about?

    Could someone add me an inverter for installation in Fusionolar?
    I created an installer account.
    I go into the app on the website, add a new power plant and try to add the device.
    After entering the serial number (HVxxxxxxxxxx), I get the error "No related device data was found.".

    Am I doing something wrong? How to add a device? Do I need to do anything on my phone with the Sun2000 app?

    The easiest way is to just install the FusionSolar app on Android/iPhone. Then you log in to this created installer account. From there, I did the initial configuration of the inverter and then immediately attached the Dongle and at the same time automatically created the installation and attached the inverter.

    If you have the error you gave, it may simply mean that there is no data from this device (you haven't configured the dongle / or it has no internet?)

    Hello
    Does anyone know how to get the European parameters or more precisely for the region of Sweden, or the Polish parameters can be the same as in Sweden. I will add that I have a Chinese version of the sun 2000-10ktl m1 inverter

    I have the same error on my phone.
    The dongle works because it has been sending data over the network for several months.
    Only the device was assigned to another installer.
    Now he has removed them and I can't add him.

    I submitted a ticket to Huawei - we'll see

    Got a reply from Huawei. But it's like, pull out the dongle, reset settings, etc. It didn't help. So I will write again soon.
    But I have a question: why after restoring factory settings, for example, I still see the previously assigned device name, or passwords do not reset?

    What to do if the inverter is switched off several times a day during sunny weather? In the attached picture, such peaks to the very bottom is the inverter turned off? And such drops not to zero, but on a cloudless day, what do they indicate? When the voltage is exceeded, the inverter turns itself off? Could it be that the electricity supplier specifically causes the inverter to shut down?

    Check the voltages.
    Shuts down at 253V (as well set)

    Today, my highest recorded voltage was 254.5V and after that there was one shutdown of the inverter, but a few days ago I saw on the graph on one of the phases 255.2V and it did not turn off. Why is it that there is a shutdown at different voltages?
  • #1129 20650677

    The inverter shuts down when the 10-minute average exceeds 253 V, and immediately when it is around 260 V (I don't remember exactly). Of course, it depends on the settings.

    You are basically grounded. You probably won't do anything about it. The topic has been discussed many times. Most likely you have a lot of installations next to each other, and each one raises the voltage.

    There is a remedy for this: increasing self-consumption during peak production.

    Well, yes - but it's such an increase that you have to use almost all of it on a regular basis.
    In practice, it's unrealistic. Well, unless someone has a 2 kW installation and drinks a lot of tea ;)
    And adding an artificial load is pointless, because what does it matter if we use this electricity pointlessly or simply do not produce it.

    You can drink tea, coffee too, but it's better to wash every day and such a boiler will draw something there at noon, and in the evening as it found.

    Exactly, I heat the 140l boiler every day, the air conditioning often works, the energy storage is charged, only I have no problem with high voltage.

    In general, a decrease in the graph to zero means that the inverter is turned off, and decreases around 1 ... 2kW look like typical decreases from cloudiness. Well, but if the weather is clear, then maybe your inverter can show interruptions in production for some reason, or there is some other reason.

    Interruptions in production are best viewed on the output voltage (AC) graph. There it is unambiguous and in this way you can verify the situation.

    You can, to prevent the inverter from shutting down:
    • 1. Use an active artificial load system that will prevent the inverter from tripping. Exports will disappear, all production will go to self-consumption plus an artificial burden. There are ready-made solutions. And there are forum threads about it.
      2. If the inverter has the function of adjusting the reactive power factor depending on the grid voltage, you can try to reduce the exported power by setting the inverter options accordingly.
      3. Harass ZE (preferably with neighbors) to reduce the tension on the hit.

    The inverter shuts down when the voltage is too high. I, however, had similar graphs, constantly shutting down production to 0 or minimum values.
    The reason was probably the optimizers, or rather their software. After properly updating the inverter, optimizers and MBUS, the problem disappeared. MBUS and optimizer updates are recommended to be done in bright sunlight.

    It's worth starting with. However, for an inverter shutting down due to overvoltage, it certainly won't help.

    Such a boiler at noon will draw paid electricity from the grid when the inverter turns off anyway. Well, unless someone has time to stand by the inverter and turn off the boiler immediately when the inverter stops producing. And if there are several pv installations on the section to the transformer, including a few switched to higher voltage, then such an honest inverter must limit production at the greatest sun.

    Well, for posterity.
    After an email exchange with support, the problem was solved.
    It turns out that entering the default address into Huawei's system was a problem.
    The servers are different and I had to enter a specific one.
    Interestingly, there is no information about this anywhere.
    So without support sometimes you can't do it, and you don't know where it comes from.

    Appropriate control even monitors the insulation and you don't have to watch anything, there are also inverters that operate such devices independently.

    Hello, it's good that I came here. I see that these are people who know the subject well. I have a question: if the photovoltaic installation is a Huawei Sun 2000 6kW inverter, is such an inverter in a different chain, exactly in the installer's chain, with which I can't get along in any way? I asked him for changing data to the router, unfortunately, I can't call him. Can I add such a device to the application? Can I add this device to my newly created installation in the Fusion Solar app? If so, tell me how to do it, because I combined in all ways and I can't do it. Such a curiosity, after restarting the inverter, I found out that the inverter was created for the Chinese market and unfortunately the language for the market was changed to Chinese, but somehow I managed it.

Topic summary

The discussion centers on issues and configurations related to Huawei SUN2000 series inverters, particularly focusing on WiFi dongle connectivity, firmware updates, and the FusionSolar platform. Users report successful inverter commissioning and firmware updates but face persistent problems connecting the WiFi dongle, which often blinks red and appears offline in FusionSolar. A reliable workaround is connecting the dongle via Ethernet cable to the router. Changing WiFi network credentials requires logging directly into the inverter through FusionSolar or FusionHome apps, as remote password changes are not supported. Installer accounts have broader configuration permissions than owner accounts, which often restrict access to settings such as location, currency, and power configuration. The discussion also covers optimal network code selection (e.g., Germany-VDE-AR-N-4105 for Poland), MPPT multi-peak scanning settings for shadowed panels, and string capacity configuration aligning with physical panel connections. Users note that inverter startup voltage and MPPT voltage ranges affect minimum panel string length, with debates on using 140V or 240V for calculations. Firmware updates are available but may not always be visible to all users simultaneously; some recommend downgrading FusionSolar app versions to resolve login or configuration issues. The FusionSolar platform's interface and permissions can be non-intuitive, with some users unable to modify installation parameters without installer access. Additional topics include inverter automatic shutdown due to high grid voltage, anti-PID function requiring external devices, and integration with Huawei DTSU666-H smart meters, which are often auto-detected. Overall, the thread provides practical advice on inverter setup, network configuration, firmware management, and troubleshooting communication issues with Huawei SUN2000 inverters and associated software tools.
