Claim 19:
20. A solar power generation system comprising:
a solar power supply;
a DC-DC converter for converting a power received from the solar power supply; and
a battery for receiving the converted power form the DC-DC converter,
wherein the DC-DC converter comprises:
a converting circuit for converting a power received from the solar power supply and being connected to a battery;
a ground sensing circuit including a plurality of resistors including a measurement resistor and a ground sensing switch and used for sensing a grounding state; and
a processor for determining the grounding state based on a voltage applied to the measurement resistor, and
wherein the processor determines the grounding state based on the voltage across the measurement resistor being within a predetermined range.
