OK, understand but i have done upgrade exactly as described in pdf, i see that on display before updates was cpu1 350 cpu2 350, after first update i saw cpu1 470 cpu2 260, after second update(downgrade) i see cpu1  372 cpu2 370.

Solar power shows the same values in device information section. In my opinion both version should have the same version, like it was before upgrading.

I was doing upgrade from windows xp and computer with real com1 port

Yes, you are right - both CPU's seem to have firmware flashed. Just checked my 20200402 inverter and it shows 470/260 as well.
Do you have a debug log from SolarPower from before the upgrades? Just to be sure to have the "real" serial#, there are lot's of fake clones arround.
Everything sounds pretty strange...
Can you post a photo of the type shield?

No i dont have debug from before,

I think we have real serial, on both inverters serial on solarpower and sticker are the same, wifi showed correct serial and was corect communication with power-datacenter.com, there was corect serial number also

I'm not sure but there is huge possibility that inwerters came from orvaldi company.

But there is no any branding on them, no orvaldi signs, stickers...

Looks ok, seem to be a original Infini 10k.

Did you powercycle (give it 5mins off) it after downgrade?

If there are still errors downgrade to version from before (2016).

Yes, it was turned off 15mins, I dont have firmware earlier than this from you Infini10KWParallel20160922P, should upload it?

Yes, this is the fw u had installed at the the beginning.

Thanks, im uploading. I m not sure if this is important but my inwerter working in grit tie mode, with no battery, I cant arrange situation according to upgrade manual to maki him in bypass mode, i can onlu press on buton then bulb glows on display in lower right corner of LCD display with no connection to AC.

OK, downgraded, got cpu1 350 and cpu2 350, inverter remebers stored settings but still, SN is 000000000000

tried to update via rs232 and USB, program says succesful, but not, serial is 00000000000.

One thing before all updating bottom line LCD with version was 000100, after first upgrade changed to 000111, and no further change, after each downgrade it was 000111 and  now is.

I just checked that bitmask at the bottom, was not aware of it at all.

As far as I see, it's related to the operating mode of the inverter (hybrid, grid-tie, off-grid,...).
So if you configure your inverter with same settings as it was before, it should come back with 000100 (grid tie). Just tried this on a spare 10k inverter and it changed from 011101 (Grid-Tie-with-Backup II) to 000100 (grid-tie).

BTW: I remember, I had a inverter without serial as well. As it was working fine, I didn't waste time to fix that.

1. Hello, thanks for the information. Inwerter is working, no errors but because lack of sn i have lost communication by wifi to power-datacenter.com. I will reconfigure it again and check that bitmask.
2. Do you have any ideas how to put original sn to the inwerter (maybye i should enter it in hex, or enter inverter in special mode).

I wanted to upgrade firmware because i want to use LI-Ion  batteries with bms , so after all i'm assuming that my device is so old and i have no chance to upgrade it

Well, maybe you can't jump directly to latest FW from your old 2016 firmware.

As you are experienced enough in fw up/downgrade now 😄, you could try to upgrade first to 20170320. Set up everything with SolarPower again and check if it's working. If ok, you can upgrade to 2020-04-02 firmware, that includes BMS support.
I have an older non-parallel 10k (build 2015) that speaks to my BMS, running a fw from 2018.

Hi, as you said changing mode is changing bitmask, but i can't get the same what i had  before. I have made settings as this from firmware upgrade manual with bypass mode turned on, ant then i will upload 2017 firmware.

I have been running my 10k inverters work Pylontech batteries and no BMS link; the BMS still managed the balancing etc so I'm not really sure what benefit you would get from linking to the BMS? Maybe just accurate percentage charge displayed on the inverter?

 

Hello, with firmware 2017 production works, not storing settings, still no serial. Then I have uploaded 2020, production not works, not storing settings, still no serial.

What SolarPower version do you have in use?

Hi user27, thank you for information, i'm assuming that you control charging process by the voltage, i know that solution

last one i think 1.18sp6

This should be ok. You can also try 1.16SP6 where I have good experience with this fw versions.

But I guess you have again ERROR 17 or 18 when running 20170302 fw (see debug log, USB-SEC-CFS). This will not let you store anything. Imho device is not fully up anyway (fw mismatch between master and slave cpu).
So I'm afraid you have to stuck with 20160922 fw.

Regarding serial I found this:

So you could give that command a try via RS232 port and the communication tool from SolarPower plugins directory:

Yes  you right on 2017 got these errors, no on the 2020, i'm sending debug file from today.

I can stay with no saving, but why is not starting production, inverter see strings and voltage on them (630V)

and from time to time shows power on strings ( also the same on Solarower) but won't start production.

2023-10-26.log

Try to set it up as "GridTieWithBackupII" and Standard VDE4105. Choose "Restore to the defaults". Wait for 5 minutes.
Does it change anything?

Pls. post a pic of the display together with the logs from solarpower.
