An MK3 interface is always a good investment 
Go to VRM and download the current system configuration…
Done that.
open them … send pics … I’m curious to see what’s in there…
and please … watch the video from above …There are, of course, other videos as well.
veeeeery small Pic … 
Only the L1 Multi can be seen here… To set up a new 3-phase system, you definitely need the MK3…
Like I said the instructions did not suggest any of this???
The video is not very explanatory. Audio clarity is poor.
There are definitely other videos in English… I only have ones in German… but these two are good and you could use the subtitles…
what is happening if you “Setup VE.BUS System” … i have never used Victron Connect for this case …
Nothing, its greyed out.
Where can I get a MK3 interface from?
You can get an Mk3 interface officially
or through a “classifieds market”… Resale market …
Maybe you know someone nearby who can lend you an MK3 interface… wherever that might be…
I have now managed to program the VE Bus to 3 phase. and load the ESS assistants, All the settings seem normal but the relay test is still pending.
What do I need to do???
I have read the config from on another device using remote VEConfigure and all seems as expected.
Still have the problem Relay test still pending!
