Seems like no one's interested to help.
 
In all cases, I resolved my issues.
 
Contacted support in China, they sent some steps which were already executed before and nothing helped.
For some reason I was unable to access 192.168.10.100 even after resetting the device (held the key for 6 seconds and got the 3 colors blinking) and accessing it through hotspot (steady blue light). Then I was able to add the device to my datalogger list but was unable to connect to server.growatt.com (showed as offline on the shinephone app).
 
What caught my attention at this point is that after resetting the datalogger, it's name was always being set to "Left Wifi" which is a name that I gave the first time I had installed it. This is weird because it shouldn't be that way as I had reset it to factory settings and the normal behavior was to see the device's name with it's serial number instead of "left wifi".
 
When accessing the device through hotspot in the ShinePhone app again, I noticed that there is a place to enter "advanced settings" just before setting my internet connection's wifi and password. The advanced settings require a password which I got to discover that it's "growatt+date" (date is: yearmonthday, i.e. growatt20220531). I did not change anything in the settings, I only saved and the datalogger was recognized like last time but this time it was able to connect to growatt's server.

Some good news.
Amos in China asked me to send him screenshots and videos of the problem. All this I had done before. But I went through the whole process again.
This was three days ago.
So I just left it with the solid green light on. That evening I decided to give it another go but before I did I actually had deleted the Datalogger both on the server side via the PC software and also on my phone.
When I got to the Garage I saw the blue flashing light which means it's working and transmitting data. Lo and behold I open the phone app and it's working. No sign in required no datalogger verification needed. Checked the PC server website and everything working too.
So what did they do and how did my logger reactivate as if by magic?
That was my question to Growatt. Their answer "It may be caused by our server. You can observe it" - Whatever that means. This was from the email I received this morning.

Let me go back a week or so. I specifically asked them if the verification with the CC code is done within the datalogger or whether it's done at server level. Their answer was it's done in the Datalogger which would make sense because it hasn't connected to the server before validation. However with this "magic" fix that happened all by itself I am starting to think it was corruption on their servers all along and that there may be a two level validation process.

Be that as it may, it is back in operation with a two week gap now in the historic data. At least I have the Solar Assistant data.
   

okay, after talking to Growatt's support in China, they informed me that ShineTools is only used with on-grid and not off-grid inverters.

Hi Zsde,
I tried all kinds of tricks there is out there.
Ended up talking back to the Growatt support and they recommended that I use ISP TOOL 4.3 which worked like a charm.
(if you need the tool, i've already attached it to my post on another forum - https://diysolarforum.com/threads/growatt-spf-5000es-firmware-update.35171/page-3#post-508910)

Your cutoff voltage is on the low side, unless you don't mind risking a reduced lifetime of the batteries.
Here is a table for typical 12V Lead-Acid chemistry. Multiply those by 4 and decide if you wish to remain in the green band. That would be the suggested cutoff V.

Have a look at this thread. All your other questions are answered in there, including the downloads and files you are looking for.
