Innovative DC Filters for PV applications

PREMO 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 PREMO DC filter series help 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.

This innovative PREMO DC filters has been designed and built according to UL1283 and EN60939 normative.
