MultiPlus + Cerbo. Shore power to outlets without charging or inverting.

We have a MultiPlus 12/3000/120-16, Cerbo, Orion Jr2 BMS etc. On Cerbo we have 4 modes for MultiPlus: "Off", "Charger Only", "Inverter Only" and "On".

What I'm missing is "AC direct", meaning no charging, no inverting, just AC coming from shore power and going to our 240v outlets.

In our old system, before LiFePO4 and MultiPlus we had a relay doing this. Now with all these "smart systems" we thought that they could be configured the way we want to. But so far haven't found a way.

We would hate rewire everything and go back to an "external" relay.

Our solar panels can handle our DC demand, so there is no need to charge the batteries while plugged into shore power. We just want to be able to use 240v appliances without turning everything on and off all the time. Our system is basically designed to be used off-grid, but every once in a while we find ourselves in a marina...

Hi @Johanna

You could just untick the 'Enable Charger' box in the Multi. This can be a little onerous to do frequently, and you'll need a means to access it: https://docs.victronenergy.com/veconfigure.html#inverter-settings

Or you could finess it by lowering the charge settings to just hold a Storage V on your batts.

If you need help doing any of this, just ask..

Another way is to limit charge current in the DVCC menu of the Cerbo GX. Advantage: easy accessible.

Correct, this feature is lacking.

A workaround is the ability to change the Multiplus charging current thru the UI.

Quite the hassle that there's no way to do this from the Touch/Cerbo, but you have to go through VE.Configure. Or am I missing something?

Why is there no possibility to set AC input limit to zero (passthrough) via gx touch?

With the older Multi control panel it was easy to turn the limit down to 0

Please put this feature in with the next update!!!
