Methods and systems for operating a power generation system

A photovoltaic (PV) power generation system (100) is described. The system includes a plurality of PV collector units (102) that include at least one PV cell (124) and a collector-side single-phase inverter (122). The plurality of PV collector units are configured for coupling with a symmetric poly-phase alternating current (AC) load (18). The system also includes a system controller (108) configured to control operation of the plurality of PV collector units.
