Hello, I currently have 6 Pylontech US5000 batteries connected through a LYNX distributor to Multi RS Solar 48/6000 and Ekrano GX. My total solar power is 4kW. My electric panel is wired for three phase, but the grid connection is single phase 40A. I'm thinking of adding two more units. (I do understand I will overload the grid fuse if all three will charge the battery, so I will adjust the charge currents accordingly.) Alternatively I could just connect one of them to the grid.
Questions:
Can and should they all be connected to the same battery bank?
Can I expand my setup so that I will have three Multi RS Solar 48/6000 with 4kW solar each being fed AC through that single 40A phase from the grid and configure them for three phase output? I have no three phase motors so I will not mind all the three phases being in sync. Or should I just connect one of them to the grid? Will this then result in true 3-phase output?
