Abstract

A power conversion system (10) comprises: a plurality of inverters (INV1 to INVn) which are connected in parallel on the AC side; and a controller (1) which controls the plurality of inverters (INV1 to INVn) using a set value (CL) that is smaller and a set value (CH) that is larger than the value that is calculated by dividing a request power value (DM) requested as the total output power (PQt) of the plurality of inverters (INV1 to INVn) by the number (n) of the inverters.
