question

Hi @Gary@105, unfortunately this is not possible. If you're trying to use the MultiPlus as an inverter only (which is why I presume you're trying to set the AC Input Current Limit to 0), then simply switch the MultiPlus to "Inverter Only" in the CCGX device menu.

Hi @Justin Cook - Bay Marine Supply USA, thanks for your answer.

You are correct, I am attempting to set the current limit to 0 so as to disable charging (i.e. Inverter only mode). I cannot use the switch function on the CCGX as this is disabled when used with a VE.Bus BMS, refer below:

Prior to firmware V2.40 the current limit was also disabled and there is no mention in the firmware change log, announcing the change, that there is any minimum limit to this setting.

According to the minimum shore current limits spreadsheet there is no minimal limit when PowerAssist is disabled.

Any thoughts?

Thanks
Gary

@Gary@105 hmmm it is indeed interesting that no minimum limit is listed; my understanding was that in mode "On", 2.4A was the minimum AC Input Current Limit under any circumstances for your model and that it could only be adjusted to 0A when switched to "charger only" (thus allowing straight AC pass-through, which is the opposite of what you're trying to do).

I have a 12/3000/120-50 120v MultiPlus in a display here at the office and, even with PowerAssist disabled, I can only dial down the AC limit to 3.5A in "on" mode - to get it to 0A I have to switch to "charger only" first, then dial it down.

...I am now unsure whether this is a bug or a feature. I will make inquiries with Victron about this and whether there is another way to switch to "inverter only" mode, since that's what you're really after.

@Justin Cook - Bay Marine Supply USA thanks for your response. Hopefully Victron will answer your inquiry with some positive news.
