The present specification relates to a photovoltaic system to compensate by using an energy storage device when a load or a system is used a lot and unbalanced in a system-connected photovoltaic inverter. To this end, according to the present invention, the photovoltaic system comprises: a solar module for generating power based on solar light, and providing the generated power; a solar light inverter for converting direct current power transmitted from the solar module into alternating current power, and supplying the converted alternating current power to a system; and an energy storage system for providing pre-stored current to the system when power needed during a preset peak time or in the system is greater than power which can be provided by the solar light inverter. |
