Typical Electrical Schematic
Overview
These lters are adapted to attenuate high frequency
noise that may be degrading performance or a lifetime of
photovoltaic panels. They will also reduce the radiation
of EMI noise that may emerge from the panels and the
connection cables. The lters are optimized in geometry
and are designed for the lowest power loss. Two versions
are available, with or without Y capacitors, to support
varoius inverter topologies. X and Y capacitors are selected
from KEMET’s wide range for highest performance and
reliability.
Applications
This lter is intended to be used in photovoltaic applications
between the solar panel and the inverter system, and can be
used within the specications in any other DC application,
e.g., battery chargers, energy storage systems and UPS
machines.
