SCHURTER 2300 A FMER SOL interference filter is available without ground capacitors to safely prevent any leakage of current to ground. Products are designed for use on the dc side of the inverter in photovoltaic and other dc systems. Maximum Power Point (MPP) trackers generate disturbances into both the grid’s ac power line, as well as the dc side of the solar module. An ac filter is typically used on the grid’s ac power line, but the noise generated on the dc side tends to be overlooked.
