DC Filter FN2200

EMC/EMI Filter for PV Inverters


EMC/EMI Filter for PV Inverters

  • Reduces conducted emissions towards the solar panel
  • Reduces the probability of EMI radiation off the solar panel
  • Helps to prevent pre-mature panel aging because of HF leakage currents
  • Helps to meet international EMC regulations for the entire PV system
  • Most compact standard solution in the industry, optionally available without capacitors to ground (B types)
  • New: up to 2300 A

Features and Benefits

Installed between the PV inverter and the solar panel, FN2200 DC filters help to control conducted emissions on the panel side of the system and therefore reduce the potential for interference radiation off the panel. The filter also protects the solar panel from HF stray and leakage currents which can cause pre-mature aging in the PV modules.

Typical Applications

FN 2200 are primarily designed for PV inverters. However, they can potentially also be used in other DC applications within published specifications, like UPS, DC motor drives, or DC quick chargers.
