PROBLEM TO BE SOLVED: To provide a feeder system capable of making effective use of the power of a storage battery. SOLUTION: A power monitoring circuit 10 compares load power with reference load power W1. An inverter 2A is stopped when the load power is lower than the reference load power W1, and the inverter 2A is operated when the load power is higher than the reference load power W1. The inverter 2A is set so as to positively output the power equal to or higher than preset minimum reference power during operation. It is thus possible for the inverter 2A to conduct power conversion with high efficiency at all times, and make effective use of the power stored in the storage battery 1. |
