A power control system includes a battery, a battery power inverter configured to control an amount of the electric power stored or discharged from the battery, a photovoltaic power inverter configured to control a power output of a photovoltaic field, and a controller. The power outputs of the battery power inverter and the photovoltaic power inverter combine at a point of interconnection. The controller adjusts a setpoint for the photovoltaic power inverter in response to a determination that the total power at the point of interconnection exceeds a point of interconnection power limit.
