PROBLEM TO BE SOLVED: To provide a multiple power conditioner system that can effectively utilize a generated output of a photovoltaic system even during output suppression.SOLUTION: A multiple power conditioner system 10A comprises: a photovoltaic system 20 and a storage system 30 connected to respective power lines L2, L3 branching from a trunk power line L1 connecting a system G and a load R; a bypass power line LB connecting a generating side DC power line L4 to a storage side DC power line L5; and a suppression condition determination section 26A for determining whether or not a predetermined output suppression condition is satisfied. When the suppression condition determination section 26A determines that the output suppression condition is satisfied, DC power produced in the photovoltaic system 20 is supplied to the storage system 30 via the bypass power line LB.
