Solar Interconnection Methods (Full Guide)
My intrepretation of "hot-bus" is that it''s a meter-main combo with no main breaker. Your sub-mlo 200A panel being protected by a 100A in the main panel with 100A of solar would be compliant with the 120% or backeed rule. Because the combo panel doesn''t have a main the backfeed rules don''t apply there so you''re good to go.
