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

I have no idea what to enter at home.

I came to the point that the tab and the value entered in it, for you "On-grid price", for me "Price of supplied energy" does not matter, although there must be something entered, preferably the same as you enter in the "Price of energy purchase".

In the "Purchase price of energy" tab, I entered the price of kW / h calculated from the invoice, the value of the invoice: quantity consumed kW / h = unit price kW / h, in the simplest terms, the price includes distribution, fixed charges and the price of energy.

As I wrote earlier, this option is a gadget for me, which only approximately / indicatively tells us how much we saved on the produced energy, about the 20% "tribute", it could be worked with the unit price, which we enter, for example, reduce it by 20% , or subtract the 20% from the one calculated by FusionSolar

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?

For me, it is in the attached donglu, which is both AP WIFI and has an ethernet connector.

Hello, I have a question, maybe you know what to do to get more network codes, I only have 3:
CHINA-LV220 / 380
CHINA-NB / T 32004
Custom (50Hz)
even after updating the inverter firmware?

I was immediately full. Weird. What distribution do you have the inverter from? Where did you get it?

To properly start the inverter, you must allow the application to access the location - this should set the appropriate grid codes to choose from.
I suspect that you need to reset the settings and re-commission the device.

Thanks for the quick reply gentlemen,
So this is an inverter bought on a well-known auction site , the guest has already sold it a bit, so it's more distribution to Europe, not China (I was suggested on the Huawei forum). The location was shared at startup. He will try to reset the settings and see himself.
And for you when you first install it, you can see the full list of networks right away or only 3 of me?

I have a choice of 29 networks.
However, I do not have the 2 Chinese you gave among them, but 1: Taiwan, China-TAIPOWER

Hello,

When it comes to configuring the SUN2000, I have such a problem that after installing a new device, I cannot log in to it.
I have FusionSolar v.2.6.3 installed, I have created an installer account, I have connected to his internal WLAN network (from the code on the casing) but the program does not go any further until the installer password is entered, it just thinks and thinks as if it crashed.
Does anyone know what this may be about?
Meanwhile, FusionHome works fine and I can log in normally, but I cannot use it to configure the WLAN_FE-10 dongle because it is not possible.
How can I fix it?

Best regards.

I did that too. Up to point 6 it's going well. I can't wait for point 7, i.e. the possibility to enter the password :(

PS I have the standard 00000a password because FusionHome is good on it.

Try it like this, in point 6, when you see the QR code scan, click on the bottom Manual connection, on the next screen click on WLAN at the top, then click on the inverter's WiFi network and the login screen should appear.

Hmm, I tried that too. It connects to the WLAN and continues to "spin the wheel" waiting for the login screen.

Well then zonk, no ideas, probably something with a connection.

Thanks for the hints. I removed the program version 2.6.3 and replaced it with 2.6.2 and everything works.
Best regards.

If you go back one more version, to version 2.6.0, you will have the inverter temperature indication in the app, which has been removed in newer versions of the app.

Hello
The problems with the application have been mastered, but I still have a problem with the first start-up, the inverter shows no voltage on the DC side, where the measurements show that everything is OK

Did you turn on Hebel DC in it?

Yes of course

Do you have the option of measuring the DC voltage at the input to the inverter? E.g. on the surge voltage, the base of the DC fuses, if there are any, or the DC switch if you have installed one, if there is the appropriate voltage there, and the inverter continues to report an error, you should look for the cause in it.
Otherwise, look for a problem in the panel connections and cables going from them to the inverter, MC4 connectors, or whatever else you have.

Welcome

Measurement with the inverter turned off shows 279 V, and when the inverter is turned on, the measurement is 1.3V

Disconnect the DC cables from the inverter and then measure the voltage, as it will be appropriate for the inverter to start, and it does not, look for the reason in the inverter, report to the installer how you did the installation yourself, then advertise where you bought it, if you can get advice from the official distribution Huawei.

Ladies and Gentlemen, does anyone have an idea what to do when the dongle from the Huaweia Inverter, which after replacing my livebox router, stopped communicating with it and now flashes red?
There is no option via the FusionSolar app. Resetting Livebox also does nothing.

You need to log in to the inverter with the FusionSolar app and change the WiFi data.

You can also try to name the WiFi network as in the old router (SSID) and use the same password, it will not work as above, configuration after logging into the Inverter.

Gentlemen, I will want to install the Huawei DTSU666-H smart counter. The connection itself does not seem complicated physically and I'll get it. But suggest whether you need to configure something in the inverter software? Or will the inverter automatically detect this counter?

If there is a need to configure, tell me how to do it?

Take a look here. Lots of technical information: https: //www.youtube.com/watch? V = uIJfWFNq0HU

Have any of you enjoyed the Anti PID feature. From what I read, when it is turned on, it reverses the high DC voltage to the modules at night to compensate for losses due to the PID effect. The only question is which compensation direction should be set or whether to leave the 'output blocked' option?

I think you need a dedicated external device to support this function.

I watched, everything is nicely shown how to connect in the switchgear and at the inverter, but the moment that interests me is omitted. Only at the end it is shown in the application that the meter is working and how to block the energy going into the network.

For me, the Sun2000 8ktl inverter automatically detected the meter. Nothing needed to be set.
