Schurter has added a new standard DC filter series FMER SOL designed for use on the DC side of the inverter in photovoltaic systems and other DC systems. MPP (maximum power point) 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. EMC standards EN 61000-6-3 and EN55014-1 also place strict limits on the noise generated downstream from the grid, such as the line to the solar panels. Using the FMER SOL DC filter on the DC side of the inverter ensures EMC compliance and overall reliability of the entire PV system.Find more information on the Schurter website.
