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

What, then, should I set something on the network? VDE ARN 4105 is the default but it is a German network.

My inverter.

>>20566618What's there in this other post that isn't in this?

At the beginning, I will refer to the fact that there is information that the installation is in Norway and the electricity goes to the operator in Norway, not in Poland. But about this 2 sentences at the end.

After analyzing and counting, it turns out that everything is well-chosen. I have 2 suspicions, wrong connection, as one of my colleagues has already mentioned, 11A is over.
I didn't have 10KTL-M1 in my hands, so here's a question for you. Do you know which terminals the installer connected the DC strings to? In KTL 4,6,8 version M2 number of connectors = 2x number of MPTT. It connects to pair 1 and 3, because pair 1 and 2 are MPTT1 and 3.4 MPTT2. I don't know if it's the same here.

The second issue is that someone set something wrong. It is definitely a mistake to set the network to the Czech Republic. You know ... a few years ago, when the networks were crawling, the "installers" made such rubbish in Poland that they uploaded the Czech network, instead of making generic and entering the parameters from the finger. They argued that it was also 230V. Except the frequency limits, disconnection voltages, and a few bugs were completely different.

Later, they started to set up the German network in our place, it is much more similar to ours, apart from a small detail, our maximum voltage is 252V, Germany a few volts higher. Installers still believe that if the inverter turns off too often, you have to switch to the German network instead of verifying what is wrong with the installation. With my own eyes, I met such a bummer that the "installer" put on 2.5mm2 about 40m and when the inverter turned off, he ordered to switch to the DE network, it helped a little but not well. I suggested to a friend to replace it with a minimum of 4mm2, he went crazy and assumed 6mm2. PL network settings, shutdowns still occur but sporadically.

In addition, important considerations for introducing substandard voltage into the grid are very high fines, or seeing a square sun. And hardly anyone will tell you that the meters have the ability to record the maximum voltage that is introduced to the network, just as they register reactive energy, cos fi max power and a few other parameters. In my area, people have already received "penalties" for the fact that the paper was 8kW, and the falowik was 12 and additional panels were added, without notification.

Returning to the installation, it suggests changing the network to a network with the correct parameters. Check with the configuration required by the operator.

Alternatively, there is always a factory reset and setting from scratch. I do not know how in Norway, but in Poland, when I got equipment from customer import (from DE), the inverter at the first startup based on GPS location detected that the network is in Poland and suggested changing the network to PL. It was really hard to screw this up.

Now these 2 sentences... I'm a bit surprised that someone is downloading equipment from Poland to Norway, there is no equipment there!? It is also strange that a Norwegian electrician makes such a shameful mistake as setting the network to the Czech one. Or maybe it's his "Swedish" electrician who went to pick strawberries and decided to earn some extra money I do not judge. However, as far as I know, Norway and Sweden have one of the strictest energy laws. There, if your housing from the socket breaks, you can't do anything but call an electrician and only he can come to fix it. It doesn't matter that the repair does not require unscrewing the screw from the cable ... you don't move the electric device and that's it.

Or maybe read and understand everything he writes.
Your inverter has 230V, 4-wire installation, i.e. you have the following voltages:
L1-N 230V
L2-N 230V
L3-N 230V
and in Norwegian a 3-wire installation, i.e.:
L1-L2 400V
L2-L3 400V
L3-L1 400V

^^^ here's a mistake thanks for the explanation man learns all his life.

Seemingly the same, but not quite ... if you do not understand, it means that there is no elementary idea of \u200b\u200belectricity.
And if you don't understand it, then don't try it. ELECTRICITY IS NOT A TOY, ESPECIALLY WITH SUCH POWER. You can experiment with what happens when you drink a liter of milk and eat a jar of pickled cucumbers...

What about this current in Norway ?

Don't worry, it's the same current as in Poland, although there are legends about its presence in every cable.

The basic information and fact is that in the socket we will not find plus and minus, or even plus and mass. The household electrical system is dominated by alternating current with a voltage of 230 Volts. Of course, there is also a connection with a voltage of 400V, but this voltage will only be in the fuse box. An electrician can easily prevent your oven from baking pizza twice as fast 🙂 . To sum up, due to the fact that almost all household appliances need 230 V to work, this voltage will be supplied to them.

Why do they "kick" both wires?

in the vast majority of households in Norway, the power company supplies electricity in the IT system, where both wires are working wires, i.e. live. The voltage between them is 230 V, while between one of them and the protective conductor (earth) is within 140 V. This is why if the current finds its way to the ground through your body, you will be electrocuted. Consolation is the fact that now all circuits are protected by residual current devices, giving excellent protection, provided that the grounding is effective.

three phases, force or not force?

Colloquially known as the power is the voltage of 400V in a three-phase connection. Three phases in Norway are not always 400V. Often residential buildings are supplied with three phases. However, the voltage between each phase is 230V.

This is extremely important when ordering equipment from Poland. When ordering, for example, a jacuzzi adapted for single and three-phase power supply, we may be surprised by the fact that the three-phase option will require 400V and despite the fact that our box has three-phase main protection, we will only be able to use a single-phase connection, and thus we will not get the full power of the device. https://www.elektryczny.no/2021/05/what-with-this-current-in-norwegii/

Everything is correct. I use a transformer to power 400V equipment.

Hello.
Today I took a look at the roof - it's a bit hard to determine the course of the strings now, but I noticed that the wires are lying on the roof in several places. The 10KTL-M1 inverter has 2 MPPTs with one output for each. Today we tried to disconnect the power from the roof, one at a time, for each MPPT. The total power of the strings delivered separately was 8500W, but when both are connected to the inverter at the same time, the inverter cuts the active power to 7000W. On Sunday, we will assemble a makeshift installation from the same panels and an 8 ktl - m1 inverter in the warehouse and see if the same problem occurs there. We will compare the parameter settings and possibly clone from one to the other. Restoring factory settings is valid when the behavior of the test installation will be satisfactory, and no actions aimed at resuscitating the inoperative installation will be unsuccessful. As for the settings of the Czech network - it's my job, not an electrician. The default network jumps VDE.... - German means. According to all advisors, electricians, fitters and courses for PV installers, Huawei inverters do not work with the IT grid. I suspect that the designation of the 400V mains voltage, after choosing a three-phase, three-wire installation, confused not only me. 400V in this installation may occur in front of the transformer, somewhere out there, far away in the district - at home, somewhere.
I will inform you if the status of the case changes.
Thank you all for your willingness to help.

400 V in an IT installation does not exist. There is an inaccuracy in the inverter settings for the given network.

But what network do you want to connect it to, to simulate this at all you would have to have a Norwegian network.

And have you tried this:

or...
Maybe you'll just call Huawei, contrary to appearances, quite easily. And since they say that the IT network is supported, they should tell you how to set it.

PS I still bet it's a settings issue.

Velkhor, you need to change the way you communicate with people. You are very unpleasant and provoke antagonism. You write that I repeat nonsense, but I did not claim that inverters do not work with the IT grid. Not only that, I tried to convince everyone around that they work with the IT network. I live in Norway and the network in stock I have my own IT. I called Huawei. Despite my sincere desire, I did not get an answer - although the guys tried very hard.
You have knowledge, you want to share it, but you shouldn't do it in the usual way, it spoils the atmosphere on the forum a lot.
Positive greetings.

I propose one more experiment to reduce the power of the chains to about 7000-8000W
I wonder if, by analogy, the inverter will cut power below 7000W.

It is worth a try.

WS Transport AS wrote:

Ok, I'll try to be less provocative. But somehow, from the very beginning of the discussion about your installation, you made a bad impression on me, because you provided fragmentary information and concealed, whether consciously or not, very important things.
There were already a few people who had a problem and did everything to help those who wanted to help them.
APPROX. let's forget about it let's start from the beginning :)

You didn't deny it, you didn't state that you had a different experience, so I assumed you agreed with the text you quoted.

I have another idea of "cutting power". You can review the history and see if there was a clipping to 6.8 or 7.3 (something other than 7-7.1).
And here he would ask for a graph but from a beautiful sunny day without clouds of voltage on the L1-L2, L2-L3, L3-L1 phases. And I don't know if the L1, L2, L3 voltages, and the inverter power graph will be available.

Hello again.
After many attempts to change the settings, I come to the conclusion that either the panels are defective or the overline is not optimal for maximum energy yield. Max you get out of the panel is 7A. Rated power current of the panels is 10.72 A. The panels are mounted on a house with a gable roof on a slope facing south -10 degrees. The slope of the roof seems to be a bit too small, about 15 degrees. We will wait a little longer for the operator's response regarding the settings and try to enter "by finger".

Thanks for the drops.
And ass, with my idea. I was hoping that the problem would be too much asymmetry of the voltages L1-L2, L2-L3, L3-L1. But it looks good.

WS Transport AS wrote:

The output graph shows that the cutoff is an inverter issue, not a panel issue. I don't think it makes sense to look for a problem here. There is no current limiting device in the panel. It is limited by the internal resistance. If the panel did not keep the parameters and max had 7A, the graph would be such a nice sine wave, without flat cut, only max would be 7.
And post a graph of DC voltages and currents from 06.05.
How did you check it, when connecting to the inverter, the MPPT on the inverter cuts like that. You won't be able to measure it that way. It was ideal if you had a meter for measuring PV installations, there is a short circuit measurement, but you can also measure it with a multimeter (just set the right range so as not to burn it, 20A is enough, if you have a 10A chance that you will fail the meter).
If you want to measure it for your safety, do this:
- disconnect 1 panel from the string
- connect the PANEL in a series - a multimeter - some switch may be from the light, it should withstand 1 measurement (do not measure directly in the plugs, they are not designed for sparking and there is no point in torturing them.
- you only measure few seconds (so as not to torture the panel), remember all the power will be deposited on the panel in the form of heat.
ATTENTION: the voltage will be about 50V, so you can already feel it on wet hands.

The slope of the roof has nothing to do with it. Here you have a 7.2 kW installation on 7 degrees, south -8 degrees so very similar to your installation. That pin down is a power outage...

Panel data: current at maximum power (Imp/A): 10.85 (STC). It did not reach the maximum current because the sun was weak, but the graph is such a hill, without a cut.

Upload a screen of the inverter settings, but all settings, Network parameters, Protection parameters ... etc.

And this is what it looks like when you exceed a parameter and disable the installation:

definitely different than yours, with you it looks like trimming the output power from the inverter.

Here you have a case when the power of the panels is greater than the power that the inverter wants to process:

KTL5 inverter, 6.23kWp panels.

Hello,
Looking at these device data in real time, there is already a max. AC current and voltage within 140V.
The SUN10KTL M1 inverter has a max. AC current 16.9 A and at 140 V it will not squeeze more out of it, although there is much more from the DC side.
That is, the selected parameters for the country (grid) are incorrect because the inverter measures phase A, B, C voltages incorrectly.

You are indeed right The inverter chokes because it exceeds the maximum AC current, not a DC problem.

pv1 wrote:

The inverter measures the voltages well. A colleague wrote that this is a Norwegian network and there is a little different with voltages. Not like our 230/400, only the devices are powered phase-to-phase and the phase is actually about 130V.

There seem to be 2 possible solutions. Replacing the inverter with a larger one, or adding a 3x400V / 3x230V transformer.

pv1 wrote:

Hello,
... the inverter measures phase A, B, C voltages incorrectly.

On the "CZECH" network, the inverter measured AB, BC, CA phase-to-phase.

Is cutting production not the result of the fact that max. the output current on the AC side of the inverter is 16.9A (according to the card)? The screenshots show the current on the phases approaching this value. 140Vx16.9A on each phase, it gives us slightly over 7KW in total, which is the power at which it cuts.
Edit
I just looked at the two posts above, the mystery has already been solved

Hi
The wifi dongle you bought also from China or from the local market?

I bought in Poland.

PGE sends letters to change the voltage control characteristics in the Q(U) function.
Suggest which parameters need to be changed and if anyone has experience with this mode of operation, they will share their experiences. Has anything changed in inverter operation and energy production?

1. You enter the inverter settings
2. Power regulation
3. Reactive power curve adjustment: set to "QU characteristic curve"
4. The curve settings will appear below. Default values are ok.
5. You approve the changes

Hello. I receive a message 'Device from Unauthorized Channel detected - Access denied' after commissioning SUN2000 15KTL ZHM5 inverter and when I try to add plant. Can someone help to understand how this issue can be resolved. The inverter is an imported one from China. Thanks

Do you have the "Voltage suppression function" enabled? If so, can you show where it is, but logging directly to the inverter? I don't have an installer account via www. Today the frying pan and the voltage jumps again on the third phase .... :/

It's in 2 places, here's one of them. I don't remember the second one and I'm away from home.

It's in FusionSolar on the latest firmware. This option is for active and reactive power. In the case of frequent shutdowns, I would try to enable in both places. "Installer" access is needed.

@xszuflax I have downloaded the latest firmware 6.24.00.111 for the application and installer permissions. I don't see this option anywhere. And anyway, on FS in this latest firmware in "Parameter Settings" there is a negligible number of parameters to change. Only 6 items.
Can you indicate where to look?


There are definitely more configuration options in the SUN2000 application version 6.24.00.111, but I cannot find the "voltage suppression" setting for active and reactive power there either.
