A power conversion system includes a photovoltaic source to generate direct current (DC) power; a direct current (DC) to an alternating current (AC) single stage inverter to convert the direct current (DC) power from the photovoltaic source to alternating current (AC) power for delivery to a power grid, and a load balancing unit coupled to the single stage inverter. The power conversion system also includes a controller configured to determine a maximum power point for the power conversion system, regulate an output voltage of the single stage inverter, compute a power balance difference between a power demand from the power grid and an output power of the single stage inverter obtainable at the maximum power point and control in real-time the load balancing unit based on the power balance difference.
