I already discussed the problem here a few weeks ago. “I’m using several SmartShunt 500A units (firmware 4.19, latest VictronConnect). In the technical data is mentioned the battery capacity can be set from 1 to 9999 Ah, but I can only set it up to 999 Ah”. I was helped immediately that the problem would be solved with the new FW. I tried several Smartshunt I had in stock but could not load the latest FW. Since the articles were from June I ordered new ones. I have now received these but I cannot load the latest FW 4.20, it is only ever 4.19 and you can only set up to 999 Ah.
4.19 is the last FW version for SmartShunt/BMV:
What VictronConnect version do you have installed? *
Did you try to use another phone/tablet?
Do you get an error? Can you make a screenshot?
*VictronConnect has been updated yesterday and there is a fix for an issue with entering numbers greater than 999
you made my day! it was pretty easy… the issue was the “old” Victron Connect… sorry for borring you
