Troubleshooting • wired and wlan simultaneous connection problem

I had to reinstall my RPI4B and the setup is: a wired ethernet connection to access internet and a wlan connection to my invertor in order to read it locally. It has worked (using wpa_supplicant.conf) but now it seems I can't connect anymore to the invertor with separate ssid. The wlan0 interface gives: down and dormant on the 'ip link' command. It also shows all nearby ssids including the one from my invertor using "sudo iwlist wlan0 scan"

I scanned possible solutions in different websites, but nothing seems to work.
My supplicant.conf file is:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
ssid="SUN2000-TA22A0340087"
#psk="Changeme"
psk=11fb12966c45ebf0a4685a0b0e8331cda2c5f22e749c512ee204b9a3410ee927
}

and further :
sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
shows:
Successfully initialized wpa_supplicant

I first tried with bookworm and using nmtui but was also unsuccessfull
So I am stuck. anybody any ideas?
