A three-phase site does not necessarily consume one-third of its power on each phase. Kitchens, pumps, workshop equipment and other branch circuits can create very different phase loads during the day. The HESP platform is designed to accommodate that imbalance rather than requiring a perfectly symmetrical load profile. With a three phase inverter, panel schedules and the largest expected phase load should be checked individually, especially when several high-demand circuits may operate at the same time.
