DC Filter is designed for solar inverters.
Press Release Summary:
Suited for use on DC side of inverter in photovoltaic and other DC systems, FMER SOL series handles currents from 25-1,500 A at 55°C ambient temperature and voltages to 1,200 Vdc. Products are ENEC- and cURus-approved up to 75°C ambient temperature, with corresponding reduced rated currents. While screw clamps are available 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 less than 250 A, are available on request.

New DC Filter FMER SOL
SCHURTER presents its new standard DC filter series FMER SOL suited for use on the DC side of the inverter in photovoltaic systems and other DC systems
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.
Large solar inverters installed in electrical installations will generally require a cooling system. Components which provide high temperature resistance simplify the system and reduce the energy needed to cool. The FMER SOL filters are designed for rated currents from 25 A to 1500 A at 55°C ambient temperature, and voltages up to 1200VDC. The filters are cURus and ENEC approved up to 75°C ambient temperature, with corresponding reduced rated currents.
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.
