Why does a solar PV system create RFI?

23 July, 2010

Radio Frequency Interference (RFI) is a phenomenon that exists in modern society and is a problem in many areas of electronics.

With Photovoltaic Solar Generator systems utilising an inverter to convert DC current to AC current RFI normally presents itself in the form of static when listening to an AM radio in close proximity to the inverter location.

Normal inverter installation requirements will minimise the potential for RFI however it may be necessary to relocate radio receivers away from the inverter if RFI is a problem and/or utilise an independent radio receiver aerial to improve signal strength of the receiver.
