Power Conversion Apparatus and Photovoltaic System |
| 摘要 |
A power conversion apparatus that is connected between a solar panel and a power system, in which the power conversion apparatus includes a power generating mode that converts a generated power of the solar panel into an alternating current power, and a snow melting mode that heats the solar panel by obtaining the power from the power system, and supplying the power to the solar panel, and at the time of the snow melting mode, the power conversion apparatus controls a voltage which is output to the solar panel such that a first current value being a value where a current that is supplied to the solar panel from the power conversion apparatus is smaller than an overcurrent level of the solar panel flows in a predetermined period. |

1. A power conversion apparatus which is connected between a solar panel and a power system, comprising:
a power generating mode that converts a generated power of the solar panel into an alternating current power; and a snow melting mode that heats the solar panel by obtaining the power from the power system, and supplying the power to the solar panel, wherein at the time of the snow melting mode, a voltage which is output to the solar panel is controlled such that a first current value being a value where a current that is supplied to the solar panel from the power conversion apparatus is smaller than an overcurrent level of the solar panel flows in a predetermined period. |
