PREMO, leading inductive components manufacturer, has developed an innovative EMC filter series with application on the DC side of PV inverters.

Key points:

• Reduces emissions towards the solar panel
• Prevent premature panel aging because of the leakage currents
• Optimized for the requirements of photovoltaic systems and the whole application.
• Improve solar panel reliability and the whole application.

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.

PREMO EMC has a long experience in the design of filters for solar applications. This filter has been developed considering the specific requirements of this application, like attenuation, volume, weigh, prices, etc. In collaboration with development centres, universities, suppliers and customers, PREMO has added to its designs innovations and new magnetic materials which enable to obtain results to satisfy customer needs.

Premo EMC has fixed and on-site laboratories to carry out the EMC tests in machines or installations of its customers and a solution is given or suggested in order to fulfill a specific EMC standard.
