PREMO Announces New DC Filters For PV Applications

August 04, 2009 by Jeff Shepard

PREMO EMC has developed an innovative EMC filter series with application on the dc side of PV inverters. Installed between the solar panel and the dc-ac inverter, the new dc filter series helps to reduce the conducted emissions towards the solar panel, as well as keep leakage currents away, which produces a premature panel aging and reduces its performance.

Photovoltaics installations are the main application for the dc filters but they are also suitable when the fuel cell is the energy source.

This series is available with ratings from 55 to 1500A and rated voltages up to 1200Vdc. Custom designs are available upon request. The filters have been designed and built according to UL1283 and EN60939 normative.
