Installed between the PV inverter and the solar panel, the FN 2211 and FN 2210 DC filters are used to influence positively the conducted emissions on the panel side of the system.
Therefore the DC filters significantly reduce the potential for highfrequency (HF) interference radiation of the panel.
The filter also helps to prevent premature panel aging because of HF stray and leakage currents
The FN 2211/FN 2210 series are primarily designed for PV inverter applications between 250 and 2'300 A. However, they can potentially also be applied in other DC applications within published specifications, like UPS, DC motor drives, energy/battery storage systems, or DC charger installations.
