dedicated high current DC filters for PV inverters in
the industry and therefore are an optimum fit with
most modern PV inverter generation. In addition the
filters can be configured in a very flexible way to fulfil
customized application requirements.
All FN 2211 / FN 2210 come in unsymmetrical
housings, which help to prevent inverse installation
and wrong electrical connection. Along with grid-side
installed Schaffner AC EMC/EMI filters FN 2211 / FN
2210, the DC filters FN 2211 / FN 2210 are key to meet
the stringent international standards for
electromagnetic compatibility and help to ensure a
reliable and fault-free operation of the entire PV
system.

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.
