Hello Community, hello Victron specialists,
I was now running the 3-phase ESS system for several weeks without any problems and it behave as wished and designed! As batteries I have Pylontech eight pieces USB2000+ and my PV system is a grid based system which is not connected to the AC-OUT, but not a Fronius. In the very beginning I was stucked already somehow in "Passthru" but with the help of "R&D" specialist we could find a work around. Details here in the link.
Today I did some fine tuning with the relay assistant and changed a parameter SOC-level to switch relay k1 OFF from below 95% to switch off from below 97%.
I used the remote ve-config way to do the changes, as all the time ago. It is great to work with the remote way and not being necessary on site. This morning when the upload of the changed config file was finished the system stayed in "PASSTHRU", remote reboot, sending bad vibrations and nasty words in direction Multiplus-II GX, nothing did help. It stayed in PASSTHRU - I hate this word!
Okay I went personally to the installation, PASSTHRU as shown on the remote console. I checked everything, nothing unusual. I reinstalled the unchanged config file from this morning. No impact, no effect it stays in PASSTHRU.
I looked into the old thread and worked with the Phoenix Multicontrol panel, driectly connected with MK3 interface adjusted a current higher than 0A and, and, and ..... grrrrrh
I have to use the relase candidate 2.60 because I have an Gavazzi energymeter with Ethernet and up to today I worked with software 2.60~23 and I tried to solve PASSTHRU with 2.60~26 - it didn't help.
I switched back, removed all assistants, installed only the ESS assistant, set it up for Pylontech, installed it in all three devices as in the beginning, checked all and everything: PASSTHRU
One difference to my PASSTHRU problem weeks ago is, that this time it is only Passthru weeks ago it showed always additional #3 and #4.
I am at the end of my understanding and knowledge and hope there is anybody out there how was an idea.
Actual it is a pain! I need some beer and calm down at home! ;-)
Any recommendation is more than welcome.
