Claim Text:
1. A power supply control system comprising: a first switching section including one end connected to a battery and another end connected to a load; and a second switching section including one end connected to a solar battery and another end connected to the load, wherein the first switching section is configured to compare a first voltage that is a battery output voltage dropped by a first voltage level, and a second voltage that is a voltage at a connection point to the load dropped by a second voltage level, disconnect the battery and the load when the second voltage is equal to or greater than the first voltage, and connect the battery and the load when the second voltage is smaller than the first voltage, and wherein the second switching section is configured to compare a third voltage that is a solar battery output voltage dropped by a third voltage level, which is lower than the first voltage level, and the second voltage, disconnect the solar battery and the load when the second voltage is equal to or greater the third voltage, and connect the solar battery and the load when the second voltage is smaller than the third voltage.
