Can solar installations effect radio & TV reception?

Can solar installations effect radio & TV reception?

In recent times, we have received many enquiries from people who have installed a solar electrical system in their home or office and then mysteriously lost reception for their TV or AM radio.

This can be an unfortunate consequence of installing an inverter...but there is a solution!

Introducing Photovoltaic DC RFI Filters!

FN2200_with_logo_358x185.jpgIf you have installed a solar system that converts the sun's energy into electricity and at some point injects electricity into the electrical supply grid, then your system has an inverter. 

An inverter is an electrical device that converts direct current (DC) to alternating current (AC). The converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.

So inverters perform a very important function, but one of the by-products of what they do is that they produce some harmonics and RFI.

 

  • Serious interference with AM radio or TV reception.
  • Triggering malfunctions in nearby electronic equipment or within the system itself and with other grid-tied consumers.
  • Premature ageing of the solar panels due to superimposed high-frequency currents and leakage currents.
  • EMI Radiation off the solar panel beyond acceptable limits.
  • Potentially negative influence on panel function and efficiency.
  • Non-compliance with Utility codes, national or international EMC and Power Quality standards.

 

 

Finally, there is a solution... The new DC RFI Filter range from Schaffner!

The Schaffner FN2200 DC RFI Filter series is designed to protect the solar panels and support the PV system in meeting radiated emission standards by: 

 

  • De-coupling of solar panel and inverter
  • Reduction of conducted EMI towards the panel
  • Prevention of premature panel aging
  • Prevention of radiation off the panel
  • Improvement of system reliability and efficiency

What is Power Quality?

 

Power Quality is the field of mitigating the effects of harmonics and RFI from electrical systems. Although a considerable focus of Power Quality is the electrical environment surrounding variable speed drives and motors, Power Quality extends into virtually every facet of an electrical system.
