Using AC-out 2 while ignoring AC-in.

Dear experts,

I'm using a 48V solar system in an area where there is sometimes grid power. Because in general my solar capacity is sufficient for my loads, I set the virtual switch of my Multiplus to only charge when the voltage of the batteries drops under 50.0V. Unfortunately AC-out 2 appears to be dependent on the same AC input relay and cuts the power when AC-in is ignored through the virtual switch. However, I would like to be able to use my AC-in via AC-out 2, for certain equipment, while not charging the batteries. Is there a way to program the Multiplus for this or should I just make a bypass of the AC-in before it enters the Multiplus?

Kind regards,

Mark

You can program this with assistants, and when using assitants you can not use virtuel switches

On most models, the AC-OUT2 is downstream from the backfeed relay and so it will be off when the network is not available including ignore AC.
You'll need to connect those loads directly to network supply before AC-IN if you only use them when the network is available.
