Abstract

A photovoltaic system includes power generators configured to generate power utilizing sunlight, inverters configured to convert the power generated by the power generators into alternating-current power output to a power system, a first limiter configured to limit output power of the inverters not more than a predetermined capacity, a second limiter configured to limit output power of at least one of the inverters to a level exceeding the predetermined capacity limited by the first limiter, when a predetermined condition is satisfied, and an inverter controller configured to control the output power of the inverters, based on the first limiter or the second limiter.
