A bidirectional inverter (21) converts AC power to DC power when a battery module (10) is being charged, and converts DC power to AC power when the battery module (10) is being discharged. An inverter (41) converts DC power generated by a solar power system (300) to AC power. An alternating current path allows an alternating current-side terminal of the bidirectional inverter (21), an alternating current-side terminal of the inverter (41), and a system power supply (200) to conduct power. |
