The question is actually quite complicate.
Generally I want to know if you can build a system with three phases in America.
My background is former car mechanic (master exam) and later then I studied Information technology. I built in Austria a three phase system (3x Multiplus 5000/48) with success and I am quite familiar with Victron systems.
Now I live in Panama. For my house I will build a system with two Quattros with the 110/220V with LiFePo4 batteries. That should be easy.
But a friend of mine will build a dry chamber for drying wood. This industrial machine (from Italy) has 20kWwith three phases and he will build it offgrid, but maybe later then he will connect it to the grid, if once it is there.
So we could easily build a European system there, but then we can never connect to the local grid.
As far as I know in the US are also three phases possible (attached I found this document). Still I don't know yet what about Panama.
Of course we will contact a local electrician. But in Panama to get a good one is not that easy than in Europe or in the USA.
But generally (neglecting the drychamber): Is it possible to make a three phase system with Victron devices in the USA with the grid there?
Besides that we have the problem with the frequency. In Europe it is 50Hz and in America it is 60Hz. So I still don't know if the dry chamber is working then (but this we will find out if we contact the Italian company).
I am more than happy for any comments,
Thank you in advance!
