I am missing an operating mode for the quattro. There is no mode that only connects the AC input to the AC output without charging the batteries. In some harbors the 230V is so weak that the voltage drops to 210V if e.g. air condition and battery chargers are both active. An operating mode that only switches AC from input to output would be helpful in these situations. Yes you can limit the charge current but this is not a very convient way to solve the situation.
Hi i think you can do that with the charge current control assistant
You can also limit charge current with DVCC, I do it dynamically from Node-Red but the point is it works and you are not messing with inputs to drive it.
ESS can do it too, possibly using DVCC, honestly I don’t know, but you can set charge schedules and outside them a connected AC will supply loads in bypass, respond to AC input limits and assist where necessary all whilst not charging the battery.
What’s your end game? I suspect you may be trying tom solve a problem you don’t have because you are not yet aware of the potential solutions.
I mean no offence at all by that, we have all been there, and most of us still are at times, depending on what we are trying to do.
If you just wanted a way to control charge current, you have that now, two of them, but you may find it useful to describe what you are trying to achieve, overall, and get some boarder advice.

If you use DVCC current limitating you will also kill your free solar MPPT charging, which is not helpful.
ESS isn’t supported for mobile/marine applications.
Battery charging will obviously be reduced, but it does not affect power requirements for AC loads, as per note 4 in the relevant section of the DVCC manual.
DC loads can be an issue without a shunt configure in the DC load role.
Sorry, missed the marine context… My error, thanks for the heads up.
Possibly, depending on how it is configured and how you implement the charge current limit.
Also you didn’t say you had solar, and now you have, you haven’t said if it is AC or DC coupled.
I was wrong to suggest ESS, I didn’t now it wasn’t supported for Marine/Mobile applications.
I do now! and at some point I expect I will learn why.
There is an AC input current limit, which, depending on your system size and where the loads are connected, may, or may not, be helpful.
My Multiplus 5000’s will only implement a limit of 4A, or greater, and, so far as I am aware, the bigger the unit the higher that limit is.
I am not going to guess, and I don’t have figures to quote you for anything other than what I have here.
So far as limiting solar charge by limiting charge in general…
I don’t know if DVCC would back out solar and inverter charge at the same time or cascade the limit, taking out one or the other first.
If it were me I would be finding out, which wouldn’t take long, assuming someone cant actually educate both of us in that respect, beforehand.
Just trying to help, sorry.
