PROBLEM TO BE SOLVED: To provide: a single-phase solar light inverter which measures a leak current, using a compact insulative transformer and a general current transformer instead of an expensive current transformer exclusively for leak current measurement; and a controller therefor.SOLUTION: A single-phase solar light inverter 10 according to an embodiment of the present invention converts a DC power supplied from a single-phase solar light module (not shown) into an AC power. The single-phase solar light inverter 10 comprises: an input terminal 100 including a first input terminal 110 connected to a positive electrode of the single-phase solar light module, and a second input terminal 120 connected to a negative electrode of the single-phase solar light module; an inverter unit 200 for converting a DC power supplied through the input terminal 100 into an AC power and supplying the AC power to a system; and a leak current measurement unit 300 connected in parallel with the inverter unit 200 for measuring a leak current flowing through the input terminal 100.SELECTED DRAWING: Figure 1 |
