Multiplus II, what happens if max power is exceeded

[Rasmusm88]

Hi all

New to all of this, so sorry for my dumb question..
I plan to install a multiplus II 48/5000 gx in a insolated shed behind my Solar array 20 x 310w, 60m from where my electricity comes into the house.
I figured 4x10mm2 cable to and from the shed.
Also I have 22kwh battery bank.

But what happens if my power usage in the house exceeds the limit of the inverter @ 4000w, I think it can do 5200w for 30min tho.
Will it just flip back and get the required power from grid?

Also what will happen if I turn on say my 3phase stove, the inverter can't do 3phase unless I order 3 inverters but $$$. Is it possible to make it go back to grid and bypass inverter in this case ? Or will I have to order a single phase stove, my oven is already single phase so no problem there.

Sorry some of the questions might be obvious, but not for me, I'm trying to learn hope it's alright

Have a nice day,
From Rasmus

Your inverter/charger does not appear to support 3-phase ac bypass.

What Country are you in?
That will help us understand the utility power that you are working with.
I've never heard of a 3-phase stove but my experience is limited to North America.

Hi sorry, I'm from Denmark 230v is normal. No there has to be 3 in parallel to support 3-phase. But only interested in one at the moment

What is your stove expecting?
How many hot wires?
Is there a neutral?
I guess it will have a ground(earth) wire, confirm?

 

[Rasmusm88]

Yes neutral and ground in total 5 wires, 3 hot I guess without me being an expert

 

[Rasmusm88]

My own solution would be to wire it, so that 3phase still comes from grid to the groups that needs it, and supply from inverter to the rest, but then I won't be 100% off grid not that it matters anyway

That should work.

I found this.
Neat!

Haha yea that's it ???
