Does the AC Output #2 shut off on the Multiplus 2 24/3000/70 like on the Multiplus?

AC Output #2 on the Multiplus 24/3000/70 shuts off when the batteries are charging. We are using the Multiplus in an off grid system for household power. It doesn't appear that can be changed. Does this apply to the Multiplus 2 or is AC Output #2 hot continuously as is #1?

  • AC-out-2

    A second output is available that disconnects its load in the event of battery operation. On these terminals, equipment is connected that may only operate if AC voltage is available on AC-in-1, e.g. an electric boiler or an air conditioner. The load on AC-out-2 is disconnected immediately when the MultiPlus-II switches to battery operation. After AC power becomes available on AC-in-1, the load on AC-out-2 will be reconnected with a delay of approximately 2 minutes. This to allow a genset to stabilise.


Though, with the programmable relay assistant you can override this behaviour (not done it myself) but if you search for this topic on the forum, you will find many posts on the subject.

So the override is available for the Multiplus (1) as well?

Not all systems, particularly older ones, support assistants. You would need to check your model, firmware etc to see if it’s available via veconfigure.

It was also a hardware limitation on older models which have a different relay architecture.
