    Thanks for all the information. It seems that the configuration is ok. Now it will be a bit more difficult. You can specify what devices you have at home that consume more than 2kW. I mean the boiler (boiler), heat pump (heat pump), air conditioner (air conditioner), electric kettle (electric kettle).

    It's our new house so just an oven in the kitchen, a washing machine and for now we're using air heaters. Also, I have about 200W consumption at night from backup devices, router, alarms, cameras, etc. The strange thing is that I never had 0 from the mains.

    You have a KTL6-L1 LUNA2000 inverter. This can generate 2.5kW of instantaneous energy. So if connected to a 2kW heater, everything goes ok with LUNA. But if you turn on the 4kW heater, then 2.5kW from Luna 1.5kW from the mains. So if all the radiators are running at the same time you will still be using the mains even though you have a charged battery, there are some solutions to this but they require additional devices.

    This puzzles me greatly. What kind of installations do you have in your house L, or L1, L2, L3?

    I'm sure when I send electricity to the grid it will solve the problem, but I can't. I thought there was some setting to limit this, but I can't find it. So a possible solution would be off grid Island. Here, even when I use 70 kW per month, it is PLN 600

    I'm afraid it won't solve it. Your installation requires a more thorough analysis. I'll contact you on priv because a big off-topic has happened.

    in HA there is "Startup Time" and "Shutdown Time", unfortunately translated into Polish was wonderfully as switching on and off the inverter. This is the switching on and off of the inverter producing electricity. The inverter cannot be turned off in any software way. Even the slider you have in fusion solar turns this inverter on and off. (of course we are talking about the EU version because the Chinese is completely off)


    But who translated it like that?
    because from what I can see there is no Polish translation:

    These times of switching on and off the inverter are in fact the beginning and end of energy production, i.e. when there is sufficient voltage from the panels and appropriate weather conditions, the inverter turns on, when there are not enough of these two factors, the inverter stops producing, which is described as turning it off.

    In other words, the beginning and end of energy production on a given day.

    If you want to control the consumption, consumption and self-consumption in the future using a power meter, then in the case of switching off the inverter for the night, the indications will be false (consumption).

    Hello,

    I have a question about the counter for huawei. I bought a replacement:
    https://allegro.pl/oferta/licznik-energii-do-huawei-sun2000-vs-dtsu666-h-13011733478

    I connected the 1.5m twisted pair using one pair to the inverter socket with pins 7 and 9 according to the manual. The meter according to the seller is factory-configured for sun2000 and I actually checked the following settings:
    addr: 11
    baud: 9600
    date: n.8.1
    port: rtu

    I don't know how to start the counter in the application. I have access to the admin panel. Should it appear automatically or do you have to add it somehow? Please help as I've been stuck on this for a while now and I can't seem to finish it.

    Or do I have to connect directly to the inverter and only then will I have the meter functions?

    Added after 3 [hours] 3 [minutes]:

    I got it, after connecting directly to the inverter, it was possible to add a counter. It works without a problem.

    I understand that you can see the production and consumption in the app? Can you check it with HA?

    The original cable is 0.35mm2 (shielded CABLE), and the twisted pair is 0.127mm2 wire in the basic version, not shielded. I'd be a little scared... but I get it, you don't usually want to do the same job twice...

    If I remember correctly, it can also be added via the web. Once, I accidentally clicked on the energy storage .... and you know how you physically don't have it, but it doesn't work :D

    The counter works, everything shows as the original. I don't have the original but I think it's enough to control the network. The twisted pair is a meter and a half at most, cat 6, the fact that I only used two wires, but it has been working since yesterday, so it will probably work.

    I couldn't find adding a counter in the online application.

    In summary, the counter works and no presets are needed. We plug it in, add it in the inverter by connecting it directly with a mobile phone and wait a moment as it all updates in the online application.

    ps. everyone should have something like this at home, great for monitoring.

    It's nice that there is a cheaper alternative, good to know!

    I already have this original meter and I also used a twisted pair cable, which I had by luck going through a hole in the vertical from the basement with the inverter to the first floor to the meter. It was unused from the old days, and I couldn't pull it out or use a different cable because the bricklayer later poured cement into the hole.

    The twisted pair is fifteen or twenty meters long and the communication works without any problems, I twisted additional pairs together for a larger cross-section, just in case.

    I have a 10ktl inverter - M1, rooftop 11200W all south. The maximum temporary power of the installation does not exceed 7100W. In my opinion, this is definitely not enough. The graph is completely missing peaks, the graph looks as if it has been cut off. In the network and security parameters, the values are set to maximum. Where else can you look for the cause of limiting power? Huawei SUN2000 Inverter: WIFI Dongle Connection, Firmware Update & FusionSolar [/url]

    I can't enlarge the photo, it's hard to relate without it, but it looks rather like a power cut in production, not the maximum current.
    Can you give more information about the panels, number of strings, etc?

    I don't remember where it was in the app, but it's on the web at:
    Inverter settings -> Power regulation -> Value reduction of active power (W) In addition to the input field, you should have given limit values, for KTL-11, it is probably 0-12100 (writes from memory).
    If the installer put a "block" there, he may have done it intentionally. Huawei do not have a power limit turned on by default, at least I have not encountered it. What is your declared power connection, what wires.
    Don't touch the rest of the parameters!!!

    10KW inverter. On the roof, 2 strings connected to two MPPTs. The first string of 13 panels of 415W, the second string of 14 panels of 415W. The inverter works with the 3x230 V IT installation. At the moment, the inverter is running, but it needs to be optimized, among other things, the active power. Can someone who knows exactly about the settings of Huawei inverters, be able to conduct an online course with me and explain what, what function means, and how to select parameters in individual windows? Of course, for a fee.

    It has not been resolved. It doesn't work as it used to, so something is wrong. You can't say something works A LITTLE right, either it works right or it doesn't. Just like something not a bit clean :)
    And the fact that you didn't write that the installation in Norway is another minus, because none of us know what the conditions are there, the connections, what protections and restrictions the operator uses, etc.

    But back to the topic. From this second post, it actually looks like it's not limited by the inverter. Take a screenshot but from the computer so that you can see this line up or is it straight because it seems slightly wavy. As the wavewik cuts, it is always a "needle". Give the model of the PV panels, because I'm starting to wonder if there is a problem with the selection.

    The panel has more parameters than just current.
    But since it's fine, and you don't want to say anything about the installation specification, you have concealed that the installation is in Norway. I am asking why did you come here? Do you want to boast that everything is OK and does not work or how because I don't get it.

    Hello group.
    I encountered the problem of configuring the Huawei 10ktl m1 inverter for the 3x230V IT network. Installation site in Norway. It's just a startup problem. in network parameters I choose the EN-50549 network , three-phase three-wire installation, unearthed input with transformer. After several attempts, I managed to run the installation, but I was so careless that I did not take notes from the settings. After a month of time, the customer began to complain that the installation only gives 7 kW out of 10 kW. And it really looks like something in the settings just cut power. m experiment with the settings, as a result of which the inverter informs about the error: grid voltage too low. Has anyone encountered such a problem?

    For several years, inverters installed in the EU must support LFSM-O, the fact that our operators do not use it does not mean that it is so in the entire EU, but it will be rather difficult for you to find a RES specialist in Norway here.

    The inverter started with the settings as they are, on the Czech LV230 network - low voltage 230v. Now it comes to active power, which does not exceed 7100w and with a 10 kW inverter and 11200w panels it should give over 8000w.

    I don't understand why you don't set the correct localization norm. So in this case, the relevant Norwegian standard. After all, it depends on a number of other factors, voltage limits, etc.
    The fact that he started in the Czech Republic is not an argument for me. It could just as well "start" on many others - but is it supposed to be set like this?

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.
