The present invention relates to a method for controlling an independent photovoltaic system with a dual inverter. The method comprises: a solar cell array output power monitoring step of measuring solar cell array output power that is electric energy outputted from a solar cell array (S10); a power consumption state monitoring step of measuring the power consumption of a load connected to the photovoltaic system and determining a power consumption state of the load depending on the measurement result (S20); a storage battery available power monitoring step of computing available power of a storage battery, which can be output from the storage battery (S30); a dual inverter and storage battery charging/discharging control step of controlling the operation of a first inverter and a second inverter and the charging/discharging of electric energy in the storage battery, based on the measured solar cell array output power, the measured power consumption of the load, and the computed storage battery available power value (S40); and a load power supply control step of supplying AC power output from at least one of the first and second inverters to the load (S50). |
