MACHINERY PARKING DEVICE AND ELECTRIC POWER SUPPLY METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a machinery parking device which efficiently utilizes electric power generated by a solar cell and an electric power supply method of the machinery parking device.

SOLUTION: A machinery parking device 10 includes: a solar cell 14 converting solar light into electric power; a lifting motor 32 and a revolving motor 34 which are electric power loads using direct current power; and a power conditioner 24 outputting solar light generation power as alternating current power and the direct current power. The machinery parking device 10 supplies the direct current power output from the power conditioner 24 to the electric power loads and transfers the alternating current power output from the power conditioner 24 to an electric power system 22.
