LOM detection when feed-in disabled why ?

Hi,

I read https://www.victronenergy.com/live/ve.bus:grid-codes-and-loss-of-mains-detection :

Q4: I use ESS, but have disabled feed-back, is a grid-code still required?
A: Yes, also in this case LOM is required to make for a safe and also local regulations compliant system. Running ESS with disabled-feed-back is still not the same as using a Multi in its default configuration without ESS.

I don't understand why do i need LOM for this ? Can somebody explain ? I want to make an off-grid solar system (using Multiplus II and SmartSolar and Venus GX) and ONLY pull from the grid in case i don't have solar/battery.

In a case like this, instead of ESS rather look at using dedicated ignore AC input, or the generator assistant to control when you want to use AC.

@Murray van Graan thank you. What do you mean by ignore AC input? How would one doar that ?

Did you ever build/set-up a system using the multiplus-ii in Denmark? I am reading up on this and have a similar wish as you.

I would like to do exactly same as you:” ONLY pull from the grid in case i don't have solar/battery”

Can you advice your solution, please?
