    I would like to bring this Huawei completely offline, i.e. without internet access. I do not want to connect any devices to the Internet in any way, let alone install the app, which has been removed due to the divorce of the EU and America from Huawei in general. I don't want any dongle or anything to connect me to some Chinese site or their servers. If I let TCP packets into the local network, then only on a dedicated VLAN.
    So I have questions:

    1. Is there a computer program either via its built-in wifi or via RS485, telnet, ssh to do this first configuration out of the box?
    2. Does its built-in Wi-Fi work as an Access Point? Is it possible to set a static IP in it and then somehow I will catch this weak signal and connect it to the LAN.
    3. How can you read data from it during normal operation without an Internet connection? I don't want to let him try to send packets out of the firewall into the world.
    4. Can it only be monitored via RS485? Is there a list of modbus registers somewhere? Maybe I could scrape something on my pythone?
    5. Does this inverter have a normal website as it logs into the routers?
    6. Is it possible to update the firmware offline from a file?

    ad 1.- is home fusion.
    ad 2 - this is the AP, from what I remember you can set a fixed IP
    ad 3.- live without fusion home charts,
    ad 4. - you can search on google
    ad 5. - there is no
    ad 6. - you can by fusion home

    Hello, could someone send a screenshot of the three-phase inverter settings (mine is 8kw) from the section:
    grid parameter (grid parameters)
    protection parameter
    power adjustment
    For the standard binding for Poland - I want to compare it with mine.

    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.

    The inverter started up without any problems, creating an account on FusionSolar and updating the software went smoothly. There were problems with the communication of the key via WIFI, the FusionSolar application did not see the key although it was plugged in and it seemed that everything was ok. Only after connecting the FTP cable to the router was it possible to connect the inverter to the Internet. I don't know what I was doing wrong, but since it works when connected with a cable, that's enough for me.

    In the "String Capacity Configuration" tab, it is possible to enter a value for each PV input. By default, the whole is split evenly into 4 strings. If I have panels connected to two strings, should I divide the entire power of the panels into these two, and enter "0" in the remaining ones?

    I have a SUN 2000-6KTL inverter, please tell me where is the ethernet socket in this inverter?

    It depends on the model you have a dongle because there are and without lan only wifi and I am afraid that you have come across such a model if you do not have a choke at the bottom in the donglu, then there is only wifi at 100%

    I know that much, only I, as the owner, cannot change it, and neither can the installer, so maybe you know how to do it, then show it off ;) .

    Due to the questions.
    For those interested, I am throwing my solar panel calculator.
    It is a check of the optimal number of modules and the entire installation depending on the parameters of the inverter and the parameters of the panels being installed.
    Comments:
    1) Enter the parameters of the inverter into the "violet" color field
    2) Enter the parameters of photovoltaic panels in the "blue" color fields
    3) In the "green" color fields, we get the calculated essential parameters

    If he will help someone, I would be grateful for marking "Stars" as "Helpful post".

    Hello. What do you think about it? Voltage and current spikes when Huawei Sun2000 disconnects and reconnects. This happens on both strings, except that only the first is used Huawei SUN2000 Inverter: WIFI Dongle Connection, Firmware Update & FusionSolar Huawei SUN2000 Inverter: WIFI Dongle Connection, Firmware Update & FusionSolar Huawei SUN2000 Inverter: WIFI Dongle Connection, Firmware Update & FusionSolar

    Hello. I noticed that in my case the inverter will turn off automatically during the peak production hours - then it is 255V on one phase. Is there a protection in the inverter against too high voltage on individual phases ??? How to avoid inverter shutdown?
  • #110 19283256

    Unfortunately, there is too much production and unfortunately the tension will increase so much. In general, it should turn off your inverter at 252V - these are the requirements. How can I fix it? There are two methods. Put the load on a phase that is almost max - preferably some electric boiler or something similar. The second method is to report to the operator and report the problem. Maybe they will manage to change something on the transformer, although from what you can read on the forum it is like fighting windmills.

    Can't raise this upper limit to 260V in the inverter?

    You can only it is illegal and dangerous. If something happens to the network or the receivers connected to it (e.g. you burn your neighbors' receivers) it can cost you very dearly. As I mentioned, the fastest and probably the easiest method will be to turn on, for example, an electric boiler. For this task, you can use intelligent sockets, eg SP111, the cost of which is around PLN 50. In the application options, you have the option of creating schedules for what voltage the relay is to switch on and for which it is to switch off.

    It is known, if the cases of approaching the voltage to the maximum will increase, you have to push your operator.

    Do you have such exclusions often? What kind of installation do you have (panels and inverter)?

    Good morning,
    I have a sun2000-5ktl-m0 inverter. I want to change the wifi network it connects to. I have an owner account so logged into the inverter directly. Immediately after logging in, the application prompts you to update the software. When I try to skip the update, it logs me out. So the only option to move on is to update the inverter.
    Does updating an already configured and running inverter need to be reconfigured or will it keep all settings?
    Does the update carry any risk of failure at all?
    My current software version: SUN2000MAV100R001C00SPC122
    Proposed new version: SUN2000MAV100R001C00SPC126

    Additionally, there is something like Device Upgrade Notification in the FusionSolar app. Why can't I see information about the availability of an update here? Is there an option, for example, to increase my (the owner) rights so that I can more from the level of my account, e.g. have access to change wifi settings or update the device?

    The installer can grant additional permissions from his account.

    I would suggest installing the FusionHome app, which connects to the inverter more friendly than the Fusion Solar app, at least for me, it also applies to the change of WiFi.

    In relation to an earlier post, I wanted to ask something.
    I am a licensed installer for two installations, both on the Sun2000-5KTL-M0 inverter.
    I checked and I currently have the software version on both of them: SUN2000MAV100R001C00SPC122
    After logging into FusionSolar, I have no suggestions or information about any new version. For example, the mentioned ... SPC126.
    1) Are new versions of the inverters software distributed to all users at the same time or is it spread over time?
    2) Is it possible to somehow force checking the availability of a new version in one of the settings?
    3) Is it possible to enable / disable notifications about the new version somewhere in the settings, or disable / enable updates? Maybe I have this option turned off, so I don't get a proposal to install a new version?
    This begs me one more question.
    4) Is it possible to download the software for a given Huawei inverter model from somewhere, and is there any manual installation / update option?

    They do after updating the pop yield stats ..... For me, after the last February, the lifetime of the inverter is lower than this year's annual.

    It's not very intuitive, but I managed it somehow.
    You have to find the device yourself and the matching software.
    I just still don't understand:
    1) Why I didn't get the update from the machine like my colleague "mondo20001"
    2) I do not see any software with the ending ... SPC126 on the list.

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.
