Hi,
I am hoping someone can maybe assist me and check if my thinking is correct then.
I have a friend that wants to create a 3-phase system from a single phase grid connection.
We live in South Africa, so we struggle with load shedding (you can google what that means) which means he will need batteries for when the grid is off. He also want to have PV and push back into the grid. First question: Will it be possible for him to create the 3-phase system, have PV, have back up generator, have single phase grid supply, and have a battery storage system?
I understand that you can create the 3-phase system by using the master/slave configuration where the ACin goes into the inverter L1 and charges the batteries, and then L2 & L3 generates the second and third phase from the batteries. Will my friend be able to push back into the grid if he connects the PV system to the batteries with MPPTs?
Any help would greatly be appreciated.
Thank you.
Martyn.
