Zusammenfassung:	Provided is a redox flow battery system capable of, even when a high concentration vanadium electrolytic solution is used, achieving high charge/discharge efficiency and suppression of corrosion witha simple configuration by dissolving and removing a precipitate and by adjusting the balance of the electrolytic solution. The redox flow battery system is provided with: a positive-electrode electrolytic solution tank 11 in which a positive-electrode electrolytic solution containing tetravalent and/or pentavalent vanadium is stored; a positive-electrode electrolytic solution outgoing pipe 13 andpositive-electrode electrolytic solution return pipe 14 for circulating the positive-electrode electrolytic solution between the positive-electrode electrolytic solution tank 11 and a battery cell 2;a negative-electrode electrolytic solution tank 21 in which a negative-electrode electrolytic solution containing divalent and/or trivalent vanadium is stored; a negative-electrode electrolytic solution outgoing pipe 23 and a n
