New DC-Filter FMER SOL
Modern solar inverters, that use 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 normally 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, however, also put limits on the noise generated from lines not connected to the grid, such as for example the line to the solar panels. Meeting these limits can be achieved by using a DC filter on the DC side of the inverter.
LargcURus approval, up to 75°C ambient temperature, expected for 1st quarter 2011.
The FMER SOL DC filters are designed with screw clamps for types up to 150 A and copper bars for types upwards of 250 A. Other types of connections, such as wires or copper bars <250 A, are available on request. Small adjustments can also be made to the electrical circuit or to the filter housing on request.
