Realistically, you shouldn't draw more then 160 total amps on a 200 amp service. ( 80 % rule) This avoids the very situation the OP shared. So 24 S9's puts you right at that threshold.
Anyway, I am interested in your situation. I pm'd you.
You never specified Phases and Voltage till now. You have a small entrance of 200 AMPS, 110/220 in Quebec. I am talking about 3 phase 600 Volt 200 Amp entrance. Normally a 200 Amp entrance is 3 phase 600 volt. And we can use 120 S9s easily.
