The invention discloses a refrigerator control system based on solar auxiliary power supply and a refrigerator. The refrigerator control system comprises an MCU, a solar battery pack, an alternating current power supply and a refrigerator load. The solar battery pack is used for charging the super capacitor bank, and the super capacitor bank stores energy and stabilizes voltage and then supplies power to the load through the direct-current switch; the AC power supply supplies power to the refrigerator load through the AC switch. The MCU is electrically connected with the direct-current switch and the alternating-current switch and controls on-off of the direct-current switch and the alternating-current switch, and the MCU monitors voltage data of the super capacitor bank in real time through the capacitor bank voltage monitoring module and controls on-off of the direct-current switch according to the monitored data. The solar battery pack serves as an auxiliary power supply source of the refrigerator, depende
