There are many aspects which affect the choice of module. Totally single-phase units are rarely available beyond 20 kVA, above this size it is usually necessary to use a three-phase input for the rectifier, even where the inverter output is single phase. When feeding this type of system via a generator it is important to remember that the bypass line will be single phase, demanding a higher current on one phase only. Larger units with three phases input/output are more easily distributed across generators and can also be used to feed single-phase loads, and with good load balancing, need not be oversized
