Can you disable the "Dedicated Ignore AC input" virtual switch from the VRM portal?

I have the dedicated ignore AC input virtual switch set on my dual parallel Victron Quattro 5K system. The "do not ignore AC input" settings are configured to trigger when the SOC drops below 25% and then ignore AC triggers once absorption is finished. This is working well. When my batteries are fully charged it ignores the AC input and relies on solar. Then when the battery hits 25% the AC input charges them back up to 100% and again turns off the ac input. The problem is some days I want to override this trigger and use the AC input to charge my batteries without waiting until they drop to 25%. The only way I've found to do this is to upload a VRM config with the virtual switch disabled. Is there are way to do this from the victron connect app or VRM portal without having to upload configs?

You can adapt this article to your needs.

You are basically using the grid like a generator so use the menu from the GX to manipulate it.

Hi @jasonsele

Victron were looking at doing something like this a while back, but I'm not sure where that stands at present.

The GX relay can be operated from VRM in a couple of ways, and a wire pair from that across to the Multi could achieve this. Not sure about tapping in to VS with that signal, but I'd go straight to Assistants and do it all that way. VS can't be used at the same time as Assistants, so you'd need to start afresh possibly.

Come back if you need help with doing it.

I should mention that the only reason why I need to set the dedicated ignore AC input is because the Victron Quattro prioritizes AC input over solar input. If I don't shut off the AC input it won't use much of my solar to charge the batteries. If the priority was solar first I wouldn't need the virtual switch but according to Victron the only way to change the order is custom programming. I'll check into the GX relay option. That may be a solution.

You can do what you want with node red. You could even setup a simple switch on node red dashboard, or some dynamic input to change desired values. Both node red and dashboard can be accessed remotely thru vrm.

I appreciate the suggestion but I don’t really want to program a solution. It’s just strange that an inverter designed for solar systems doesn’t give you an option to prioritize solar input.
