    For me it looks like below, I am a bit surprised that the app suggests a different setting based on the location (I have selected VDE-AR-N-4105, and it tells EN50549-PL), the question is whether it has a current base and how safe it is to change it to your own.


    As I understood the topic, the EN50549-PL profile is a new thing and it was not there in earlier versions of FusionSolar. I have it set to EN50549-PL. I passed this information to a nice gentleman who mentioned the meter to me and he said it was OK.

    It is exactly as you write. EN-50549-PL is a grid code that has only been added in the latest versions of the software. For the sake of completeness, I will just add that the German standard VDE-AR-N-4105 (someone correct me if I'm wrong) defines higher voltage of disconnecting the inverter from the grid than the Polish standard (how well do I remember 10 V?). What it entails, probably everyone knows ...

    In addition, a lot of people probably have this standard misaligned for two reasons:
    1. There used to be this new EN-50549-PL standard that could be set
    2. By default, the inverter stood up on the German one at startup and immediately pushed the energy to the grid (new firmware forces the grid code to be set at the first start-up - which in my opinion is more correct and intuitive).

    Considering the fact that some installers have a software upgrade for customers and if everything works, they prefer not to touch (which I partially understand), it may mean that a lot of Huawei is misconfigured (by the way, I'm curious about how it is related to this certification, which the inverter had to pass from the beginning to be used - what standard had to be set then - the German one - is it ok with OSD regulations?) ....

    You also need to take into account the fact that electronic meters with data transmission (and not only) can monitor voltage levels, and in extreme cases, after April 1, it can be a great excuse for the operator to terminate the old contract and press us a "new prosumer" - because the inverter did not meet the standards required by the OSD ...

    It just works and, as I wrote in an earlier MODBUS post, I configured it in the local network, I even checked it with a quick script in python using the huawei-solar module. I don't have that much time in my life to play HA, so I turned off MODBUS. The graph from the FusionSolar application is definitely enough for me.

    I, unfortunately, do not understand how it works. By default, the coefficient at the EN-50549-PL standard was set to 1.0, I remember it well. The popular opinion shows that such a home prosumer has nothing to worry about and the problem is important for the installation of 20 KWp, also in the case of halls where a lot of energy is received by e.g. LED lighting.

    Will reducing the factor and allowing the inverter to freely produce reactive power increase the yield? I dare to doubt, but as I said electrician, I am like a trumpet from a goat's ass.

    They are going to install the dtsu666-h counter for days, I would like to prepare not to give myself a whack of groats. Does the sequence of the phases of connecting the meter have to correspond to those from the inverter or will both devices get along with each other and detect the individual phases? The second thing is whether there is a communication cable in the set or do you have to deal with it on your own? How is it, can someone give an approximate length?

    Any other things worth keeping an eye on? I know that the transformers must be properly connected but, from what youtube, the wires are well described. The order of the phases must also correspond to the order of the transformers, this is what I know.

    Rather, I meant something opposite, I thought that maybe if the inverter focuses more on reactive power compensation, it will be more loaded and will raise the voltage less. Because for some other reason the reactive power compensation settings could have an impact on the elimination of the "hedgehog" on the production graph, assuming, of course, that there is any sense in the words of the Tauron helpdesk.

    The phase sequence is optional, it is important that the transformers are installed before the first energy receiver, also before the DTSU666-H meter, it is also a receiver, the arrow on the transformers is directed towards the receivers, pay attention to connecting the wires from the transformer to the meter, this is a key issue , the transformer is mounted on the phase that is connected to the meter to terminal no.3, the wires from it should be connected to the terminals, white no.13, blue no.14 and the same phase to terminal 6, cables to terminals 16 and 17, phase to terminal 9, wires to terminals 19 and 21, terminals 24 and 25 are for RS485 communication.

    RS485 communication cable should be included, its length is ? 5 m.

    The connection from the meter side seems to me to be covered with videos and instructions. The transformers will be at the input just behind the surge arresters and before the differential devices. I remember the arrows on the gears. Does this 100 percent phase sequence not have to match that of the inverter? The HA / Fusion portal shows me V and A on the inverter side on ABC phases and the same data appears after connection on the meter side. I don't want this to be changed.

    Then you have to connect in the right order. The meter and the inverter do not agree in what order the phases are.

    If the indications do not suit you, you can always transfer the phases to the DTSU, not forgetting to move the wires from the transformer to the appropriate terminals.

    I warmly welcome. Gentlemen, maybe you can help. Is it possible to change the firmware from CN to EU? I bought an inverter straight from China in 2019, everything works without a problem, but the app recently showed a message that I have a version of the inverter for China, not Europe, but it still works properly. I am only tired of the subconscious that it is and will it be able to put the software on the EU or is it limited, blocked in some way?

    Hello, group.
    I have a question about the operation of the Sun2000 3-10 with a Luna battery in a mixed mode - ON / OFF Grid (i.e. how it is translated nicely in Polish in the manual: "work with and without a mains connection").
    So: what fungus is this BackupBox for (by the way, a box with 3 contactors, 1 relay and two watches for 4K zlotys - only such business ...)? After all, the inverter (of course after connecting the battery and SmartDongle, i.e. the DTSU666 meter) itself has the option of automatically switching to island operation after a power failure (the function can be included in the settings / function parameters / off-grid operation mode).
    Please correct me in the following argument if I am wrong:
    After analyzing the diagram of this Box, it disconnects all 3 phases of the network from the inverter in the event of loss of one (natively first - L1), gives a short to ground to the DI1 connector of the inverter and switches the above-mentioned phase to the Backup Load output.
    After the power supply from the network is restored - after 2 seconds, all the above-mentioned actions are eliminated in the reverse order.
    And there is something that I do not understand at all - it closes the L2 phase on the inverter side with the N - ????

    So, apart from the fact of disconnecting the 3 phases for order, delaying switching on and giving the signal to DI1 (which by default cuts the power issued to the municipal network to 0 - which is somewhat pointless - because the "city" is previously disconnected with a contactor) it does nothing that it would not do the inverter itself.
    And even worse, because the inverter itself, in the event of a power failure, would give a 3-phase backup with full power (well - maybe as much as the battery can do) and the original cables and this BackupBox forces you to use only 1 phase with a power of 3 kW - and with a separate cable.

    And what is actually going on in the table:
    Quote:
    Sets the SOC backup power. In the connected mode, the battery does not discharge
    off as it is discharged to the SOC backup power. After a network failure, the loads are there
    powered in backup mode.
    - well, total butter.

    I am asking - because making a call to the solar hotline H. is actually impossible, and as for the installers - for good morning, after plowing through all the instructions and diagrams, I knew more than them (because the training of sets with energy storage is just getting organized ...).

    PS. as colleagues wrote earlier - the network parameters settings for Poland appeared only in the latest firmware - but in the earlier ones there were such solar powers as Cameroon, Mauritius, Greek islands and Bahrain, and actually ALL countries of Western and Central Europe - which means that either Huawei has us deep down ... (despite the number of micro-installations greater than the above-mentioned combined) or our industry decision-makers missed the certification process ...

    I understand from the presentation videos of cobblestone on YouTube that the inverter plus luna only give the possibility of consuming energy from the battery at night / in the absence of sufficient production or recharging it in the event of excess production. In this setup, you will not start the inverter without electricity for a simple reason - if there is something working on the pole in front of your house, you will kill him. I also wonder what it costs there, I decided that half of this price is certification that it will not happen.

    buy another, e.g. 100A / 50mA and change only the gears in the meter (original is 100A / 40mA, 2500: 1) From what I remember, one of the options of the meter allows you to change the gear, it is described in the attached manual.

    Well, this is the perfect solution, but I do not see anything about it in the pdf manual or in the accompanying leaflet. There is a configuration of addresses, parity bits and bitrate.

    I was looking for a few days for a meter with transformers for 100A. Unfortunately, to no avail. I even tried to call BB PV, let them bring one to me, because 250A will not fit me. There I heard that they are no longer produced. I do not know if this is a fake or true, but I gave up and bought 250A ...... I cut the switchgear housing and fit it - it works.

    Referring to my previous post about BackupBox - attention, kol qrko, about the installer kicked on the pole by the inverter backup - justified - actually the Box must be.
    But (for those who are interested) a rough issue arose (after talking to the "engineer" from Huawei Enterprise) and the rage of the owner - the Hyundai Sun 10KW 3-phase (plus Luna battery) does not have the option of full island operation at all. There is only a 1-phase backup with a power of 3 kW, led to a separate Box output from the L1 phase of the inverter and the inverter during daytime operation of this backup does not use panel loading at all and it only takes electricity from the battery.
    Only the 1-phase version offers a full island with solar charging.

    PS. I confirm the topic about transformers. 666 in the H version there is no option to change the gear (on the other hand, tiny 100A transformers can be bought cheaply from a MEW meter), the version with factory 100A transformers is untraceable (although it does exist in the manual). I gave the outlet of the main power cables to a separate full-size box and stuffed this meter with transformers there (and it barely all went wrong ...)

    There may be a lot of things, maybe there was no phase, no internet, etc., take the Dongla out for a minute and put it back, you can also log in via the SUN2000 app (as an installer, as you know the password - the default is 00000a) and check if there is a connection to the management system, friend, the inverter was offline for almost 2 weeks, although it showed it was online, after 3 days from writing to the support everything returned to normal ... they wrote that there was a problem on their side ...

    Maybe check the newer soft - yesterday it came out SPC141 for the inverter and SPC127 for the dongle. I have the SPC140 from the first day (I did the update on December 30th on the day of launch) and it works ok, but a lot of people here and in other threads complained and did the downgrade to SPC139 themselves or asked for it support. Maybe there was something wrong.

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.
