No problem if you have any questons regarding the math shoot. I am not an engineer though.

If you have 3 s9s each drawing 6.36 amps one attached to each phase :

- Phase a-b, a-c and b-c are each drawing 6.36 amps
- each line has two s9s attached
- each line is drawing 11.01552 amps ( 6 36 x 1.732)
- watts and kwhr are still exactly the same as a single phase system
