So much for me too.

For me too, the same. It seems that this is the upper range of the measured parameter and only when the pants below it can show something ... you need to do a test and earth it, for example, through a resistor so that it is below the 3M then you will know if it measures something or only gives a constant value stored in the program . The inverter itself, during the start of synchronization with the grid, has a step that is described in the app as an insulation resistance measurement, so something probably checks ...

I also have 3M?.
As for the temperature. It only shows it in real time.
I still do not see this option in historical information, which is a pity, because it is an important and interesting parameter.
Do you have that too?

In the app, yes. I have a short-circuited inverter with HA and thanks to this I have access to the temperatures from all day. During the season, he reached 70C with his light hand at the peak of production. I added 6 60mm fans triggered when exceeding 50C and they have no major problem with maintaining the set temperature. Probably 2-3 degrees lower to go down but I don't have time to play.

I am also thinking about such a solution and adding fans. However, I have no idea how to solve it yet.
Do you have your windmills connected to a 220V power supply and triggered by a temperature sensor mounted between the rear ribs of the inverter?
I would be obliged for some information, e.g. type of power supply, fan parameters, sensor type, etc.

A total makeshift. 6 12V fans connected with each other with wires, suspended under a heat sink. Wiring connected in parallel and connected to a 12V 1.8A power supply. The power supply is connected via a smart socket, and it is scripted in HA for activation at 50C on the inverter and deactivation at 48C.

I also have 4x Arctic 80 x 80 mm F8 TC (variable rotational speed) fans connected to the HA - they turn on from 40C ...

I had the same problem and it started working after some time. No good description in the user manual. Usually it's about some detail, like transferring a password.

Bob, if the app works, you get a graph on your mobile showing how much electricity your device is producing. But what are you going to do next with the graph? You can set up reporting at https://eu5.fusionsolar.huawei.com. Then you will receive the raw numbers by e-mail, with which you can do something further.

And here I have another question. What cables did you use to connect the installation? The nominal data of this device are, for example, here:
https://sklep.sunprofi.pl/inwertery-huawei/254-huawei-sun-2000-5ktl-m1.html - they were not in the package! acc. for this, the DC input current has a maximum of 11 A, and the AC output current is 8.5 A. In shops selling cables, it is said at 5kW - the cross-section of a solid copper cable must be 6 mm2. My installer gave a 4mm2 cable and still had difficulty plugging it into the supplied plug. Do I have a cable with a utility current directed to the apartment, change it to 6 mm2, e.g. here. cable cheaper, PLN 18.5 per m2, in hypermarkets, PLN 37 per m2. Should you leave the 4 mm2? Doesn't the protection itself (yellow-green) have to be 6 mm2?

The cross-section you are writing about is rather for 1 phase. With three phases, these 5kw make 1.66 per cable, which is much less than an iron or a washing machine. Most of my friends have installations plugged into the power socket to which the 5x2.5 cable went. I had it myself 11 months ago and it worked fine but I pulled a 5x6 a week ago on the occasion of the renovation of the main switchgear, thanks to which I have a spare and I can jump from the AC switchgear to a car charger or heat pump in the future.

Thanks for the answer. The instruction from Huawei says: for AC power cable from the panels to the apartment 4 - 6 mm2,
depending ... not on the power of the panels, but depending on the power of the fuse through which electricity enters the apartment
from the power plant, because such current can go from the power plant to the inverter! Logic !

Hmm, since you changed from 5x4 to 5x6, I will also have such ambitions, Thanks for the comments.

Did your 6mm solid copper cable go easily into the plug that came with the inverter?
My installer complained that it wouldn't go in!
And it will probably be solid copper, not braided.

What about the cable between the inverter and the batteries? What is the cross section there?
I don't have any batteries yet. I'll probably add them in a few years when their prices come down.
But the cable should already be laid.

The instructions say 5, maximum 10 meters distance to the battery.
And I have an inverter in the attic, and batteries in the basement, i.e. 20 m below.
I'm a bit afraid of putting the battery in the attic, because it's heavy, moisture. And the cellar is dry, clean, at a constant temperature, well closed. If something spills out of them, a ceiling board in the attic, a nice stoneware floor in the basement.
That's why I prefer a cable that will carry these 20 m. I guess this should work. What do you think about it ?

An inverter in a damp attic when your basement is dry?! Surely you had to haul power cables from the garage to the attic anyway. Wouldn't it be better to do the opposite and run the cables from the panels to the garage?
I sent back all the companies that offered me "your" solutions (inverter in the attic, not in the garage).

This attic isn't that bad. The inverter is well shielded, bolted to a thick,
previously leveled dry wall.
I was advised against closing due to the necessary ventilation.

It is a pre-war building with four floors and thick walls made of full brick.
I live on the top floor myself. This is where the power draw from the power plant is for me.
The inverter is 5m cable above me. It is this cable that I would like to change from 5x4 to 5x6 mm?.

It is 20 m down to the basement. Here, the installer has also already given the H05RR-F 3G x 2.5mm? stranded cable.
My question - is it correct?

The next question will be about the solar cable, but I'd have to go up on the roof.
The panels themselves won't take much power, but I may want to add a few more at some point,
Power consumption from power plants may increase in the future.
The power of the battery may increase, although I have the impression that humanity will not be able to cope with energy storage for a long time.
There's also a generator in the basement in case the power plant fails.
in my city.

Please...to the inverter. I'm waiting for authorization for the dongle, maybe one of my colleagues already has the last version is 130 (it was 132 but they withdrew). Via HTTP with installer permissions you can update from the arrow...

I added to the dongle...

Thank you very much

there is a new firmware for SPC148 inverters

In about 3 weeks, a friend's company from the FV industry will be installing panels in my house. On my own, after exploring the subject, I chose the Huawei sun2000-6ktl-m1 inverter. I found a new one (packaged) at a bargain price, I went and bought it. As I began to explore the topic, why so cheap, I came to the fact that it is from Chinese distribution and that's how I came across this topic, where I got a little scared reading this thread.
I would like to systematize everything before installation and I am asking for advice on how to do it best from the beginning. Generally, I want to be able to monitor energy production as comfortably as possible.
As of today, I know that the Fusion Solar website is theoretically used for this, there are 3 Fusion Solar applications, Solar Home and Sun2000, that I will have a problem with creating an account on the website due to the use of a Chinese inverter in Europe. I bought the SDongleA-05 dongle for the inverter, because it was not with the inverter (the box was packed).
Should I update the firmware or not? Or will it update itself?
Will any of the applications work, will I have to read the energy production data only from the LAN side, will I have to use the wifi of the inverter or the wifi dongle that I bought? If I have to do it from the LAN side, will I be able to use the Huawei application, if so, which one, or do I have to do it using Home Assistant using some kind of integration?
What about these network codes, if there will be 2 Chinese and one Custom, I understand that Custom will require you to provide all the parameters yourself, any tips on how to set it up correctly?
As you can see, there are a lot of questions, I care about a specific hint that I will have to use this or that program, in one way or another. Do it, don't do it, register here or there, do it on a user or installer account.
Thanks for any tips

I also have Chinese, but I installed it before they banned it, so everything works for me, the configuration can be handled even in Chinese (2 tablets with google LENS) if you have HA, you will do your own monitoring (integration is ready), I also recommend the DTSU666 counter with a translator for less money...

You mean Chint DTSU666? Does it differ from Huawei's DTSU 666-H 3F apart from the name and price? Is Huawei only harrowing a cheaper device?

Could you suggest what and how to install on your computer and where to look for this "ready integration" to use HA?
Any tips, a link to a website or any description on the net?
Maybe there is a topic about this on elektroda.pl that I can't track down?
I will be grateful.

Look for Huawei Solar integration in HACS, installation is simple, you just need to know your local IP of your dongle..

Respected,
I bought the Chinese version of the inverter SUN 2000 5KTL M 0.
I use the SUN 2000 application.
After logging in, a message appears on the android "The device applies only to Chinese mainland if the device is used in other regions, the warranty service will not be provided and the display language will be switched to Chinese".
The Chinese language remains on the display in the application and I have a problem with setting up the inverter.
How to set the language on the screen to English?
Thank you for your help.

Hello dear :)

Please let me know if I can connect 3 optimizers on one string and 1 optimizer on the other string to the 5ktl-m1 inverter. The instruction from the sun2000-600W optimizer says a minimum of 4 pcs, but does it apply to one string? Or maybe the sum of optimizers on two strings?


best regards
Raphael.

As I often mount Huawei:


I advise you NOT to change the default WiFi password of the inverter - the reason is simple, Huawei sometimes has problems with reset and the procedure has to be repeated many times. And if we forget the password, we can have a problem.

Inverter RESET :
The inverter MUST run for at least 3 minutes!!! before starting the procedure. In my experience, turn off AC and DC, wait 10 minutes, turn on AC and DC, and wait about 10 minutes again, so that the inverter will run for more than 5 minutes. Then we proceed to the reset.

I changed the factory password and let's call it in a nutshell "I don't remember" the new password.
When entering a new one, I slipped my finger somewhere and the password is different than what I was sure of. I don't know which character in the password could be different - I've tried many possibilities and I give up.

Is it really possible to reset the inverter by turning it off?
How exactly do you do this reset?

Password reset is described in the inverter manual and looks like this:

Where are the inverter options?

Go to the inverter and try this:

1. Sign out of the FusionSolar app
2. Turn off data traffic on your smartphone
3. Find the inverter WiFi network on your smartphone and connect to it (SSID is given on the side of the inverter)
4. Click the upper right corner of the FusionSolar login screen (three dots)
5. Select "Device commissioning"
6. Scan the QR code on the side of the inverter
7 Enter the password: 00000a and you are in the settings.

If the fitter has changed the password to the inverter, you can't do anything if he doesn't give you the current one, but I don't understand what it means that the fitter restricts your access to your property, take him on the rug and talk him out of it.
If he still does not want to cooperate, then request the deletion of your account and you will set up an installer account and a user account yourself.

What if I can't recover my inverter password anyway? If I do not get the password from the installer, how do I log in to the inverter after creating a new installer account? Password 000000a does not work because it has been changed
Is there any other way to reset the inverter?
