GoSungrow ERROR: appkey is incorrect 'er_invalid

Do we have another API Key? What to find a new one?

Should I change this api application key → 93D72E60331ABDCDC7B39ADC2D1F32B3 ???

Try this link. If that doesn't help, you may need to go back to the start of that gist and work through it.

Thanks for the help.

With the key B0455FBE7AA0328DB57B59AA729F05D8, I have the error:

With the other one, ANDROIDE13EC118BD7892FE7AB5A3F20, I had "more" success, but not Authorized.

So I have one question. Should my HM be in the same network as Sungrow?

Jun 05 '25 20:06 djsilva81

After doing some research, I checked that HA can be on a different network. Probably my issue was my user.

I changed for one user with higher privileges. Now I see that I have several devices, but I have the : "Error: not Authorized".

"Request is not encrypted" is the signature of you needing to work through the gist link I sent before. Specifically Part 2 which is for Home Assistant.

Also, if you start at the top level of the this repo's issues and search for "er_invalid_appkey" or "request is not encrypted" or even the old appkey ("93D72E60331ABDCDC7B39ADC2D1F32B3") you started with, you will find other discussion around the same badic problem which may be helpful.

Please don't get put off by the title of the gist. "Compiling" the GoSungrow program was just how it began. The gist grew organically as other situations were identified. You can get past this but you do have to follow the gist.

To answer your other question, as far as I am aware, GoSungrow communicates with iSolarCloud, not your inverter. In other words, the data flow is your inverter pushes to iSolarCloud, then GoSungrow pulls from iSolarCloud. Asynchronously. That said, my inverter is on the same subnet as everything else in the house (bridged WiFi and Ethernet) so I've never actually tested a "different subnet" configuration, which is the reason for the "as far as I am aware" caveat.

I am about to talk about the iSolarCloud app. I use iOS. Your milage may vary on Android.

Most of the time when I launch iSolarCloud on my iPad I'm taken straight in. However, on occasion, it prompts me to login. When that happens I login with an email address and password.

On the first iSolarCloud screen, I tap the "Account" button at the bottom, right of the screen. The screen repaints with the "Account" tab.

Immediately below the word "Account" in the top row is my nickname plus an "owner" badge. If I click on my nickname, I am taken to a "Profile" screen.

The profile screen has fields for "Nickname", "Username", "Country/Region" and "Time zone".

In my case, the value of the "Username" is different to the email address mentioned in the first paragraph. My "Username" is a 10-character string fitting the pattern xx99xx9xxx (letters and digits). It contains no @ and no domain name. It bears no relationship whatsoever to my email address. I have no idea where the username came from. I think it was randomly generated when the installer first commissioned my inverter.

To summarise, I have three "credentials":

email address
password
username

Now, here's the point. When I use GoSungrow, I use the username and password not the email address.

Whether that's necessary is something I do not know. I have a vague recollection of my first attempt to login with GoSungrow failing (likely with "not authorised"), at which point I probably wondered whether what GoSungrow called "user" was intended to be the same as what the iSolarCloud app was calling "username", tried that value, succeeded, and never looked back.

If your account is set up in similar fashion (three "credentials") then maybe this will help.

Hello, I am an installer and can contribute to the username. When a new user is created in iSolarCloud, Sungrow automatically assigns a unique user ID. Therefore, your installer has had no influence on the assignment. I assume that Sungrow uses the unique user ID for internal user management rather than the email address. Therefore, it makes sense that only the user ID works and not the email address.
