Inverter system and solar device having same

The utility model relates to an inerter system and a solar device; the inverter system comprises a solar cell, an inverter, a first switch, a capacitor, a second switch, a first voltage acquisition unit, a second voltage acquisition unit, and a control unit; the solar cell is electrically connected with the inverter through the first switch; the first voltage acquisition unit is electrically connected with the solar cell so as to collect a first voltage of the solar cell; the capacitor is electrically connected with the inverter through the second switch and the first switch in sequence, and electrically connected with the solar cell through the second switch; the second voltage acquisition unit is electrically connected with the capacitor so as to collect a second voltage on two ends of the capacitor; the control unit is simultaneously electrically connected with the first voltage acquisition unit, the second voltage acquisition unit, the first switch and the second switch, thus controlling the first and second switches according to the first voltage and the second voltage; the inverter system has high conversion efficiency when lighting intensity is low.
