Provided is a current compensation system for solar generators for compensating for noise using an active electromagnetic interference (EMI) filter. An inverting system for solar generators includes a solar inverter converting DC voltage to AC voltage, an EMI filter unit including an active EMI filter to reduce noise corresponding to the AC voltage, a power grid, and at least two or more through lines passing a second current from the power grid to the solar inverter and passing through the EMI filter unit, wherein the active EMI filter includes a noise sensing unit sensing a first current on the at least two or more through lines and generating an output signal corresponding to the first current, an active circuit unit amplifying the output signal to generate an amplified signal, a compensation unit generating a compensation current based on the amplified signal, and a transmission unit providing a path through which the compensation current flows to each of the at least two large current paths.
