Programming a time delay for switching the Multiplus 24/3000 back to grid?

Hello,

is it somehow possible to program a time delay for the Multiplus (in an ESS system) before it switches back from battery to grid in case of an power outage?

In case of repair works on the grid I observed, that the first few minutes are often not stable and so the Multi switches to grid, back to battery then again to grid....

Is there a way to program a delay with assistants(?) with the goal to switch back to grid operation only if the grid is present continuously for about 5 minutes?

I have a hardware solution in mind but a software solution would be much more comfortable.


Regards

Rainer

Hi @RainerB did you implement the assistants as suggested by @Paul B and if so did you have success with it?

Hi @Matthew Walsh ,

I tried it only once but it seemed not to work as I expected. Maybe I programmed something wrong.

For my old Multiplus I needed anyway a second external disconnection relay to some kind of meet the grid code (in a cheap way). So I installed a 3-phase voltage monitoring item and a timer relay with which I can set the delay time.

Are you referring to where you can find to create and load these assistants on the VEconfig software? If so, disable virtual switch on the second to last tab and then go to the next tab called Assistants and load them by clicking on the add assistant button.
