The goal is to keep it balanced.
705.45(A) – limit imbalance to not more than 3%
recommended:”rings” of 3 inverters split evenly across phases
- same power per phase
- maintains existing balance of loads in panel
For inverter quantities not divisible by 3:
- determine imbalance that will be created
- determine if existing loads are already out of balance
Refer to inverter label : operating voltage range (VOC);
