Maybe it sounds strange.
I will build here in Panama a splitphase system with 2 Quattros. There will be a LiFePo4 battery with 290Ah/48V(600A max) with Lynx, Cerbo and MPPT RS.
Thats the easy part.
The battery is connected via VE.Can (its using the Pylontech protocol) to the Quattros.
But I have wood working machines from Austria, which run on three phases 380V.
Now the question:
Would it be possible to buy additional 3x Mulitplus 5000VA , configure as three phase, connect them seperate with the battery cables to the same Lynx (Distributor) system?
The second VenusOS could run on a Raspi. Maybe a smart shunt is needed for the Multiplus system?
As the MPPTs are loading the batteries (it distributes DC power to the system) it should work. Or, am I wrong?
Then I would have the split phase in my house and the three phase system in my workshop.
Of course it is expensive. But changing all the motors of the woodworking devices is also expensive.
btw: Can I use the Phoenix inverter smart 5000/48V. I mean can I configure it as three phase? Would be cheaper instead of 3 Multiplus...
ps.: the workshop will be build new. Ie. the cables would be like in Europe additionally to the 120V in separate hoses.
