It is well known that due to CMV leakage current is caused in grid connected system. However, for a standalone system the load may not be grounded. In this case, can there be leakage current due to high frequency CMV?
Yes, there is going to be some leakage currents (at least in the case of a PV installation). Check out this manual from SMA for more information.
