DC Filters for the Solar Industry

DC EMI Filters allow DC and low-frequency currents to pass through while blocking harmful high-frequency currents.  This allows a device to work correctly by diverting unnecessary noise. 

Enerdoor DC Filters were designed specifically for the solar industry.  The FIN1220, FIN1520 and FIN7212 filters are installed between PV inverters and solar panels to reduce electromagnetic interference in the DC power line.

The FIN1220.0V, FIN1520.0V and FIN7212 filters offer the possibility of ground connection separated from the virtual zero point which is beneficial for critical networks on the protective earth conductor.

Benefits of DC Filters:

  • Protect solar panels
  • Reduce EMI interference
  • Low leakage current
  • Excellent differential and common mode attenuation
