The Cotek S300-112 is quiet. Cotek and Samlex are the same company or divisions of the same company. I bought the S300 about 5 years ago and measured it with a LISN and spectrum analyzer and while I could see emissions they were well below FCC part B. I have never experienced any interference while mobile. The S300 is intended for ambulance use I was told.

Thanks Larry. I just poked both the Cotek and Samlex websites. Data sheets on the Cotek website come up missing, but some Cotek branded products are listed on the Samlex website.

The Samlex PST-xxx-12 series are called Pure Sine Wave Inverters and are specified as UL listed and FCC Part 15 Class B compliant. xxx is the power rating in Watts. Amazon shows the PST-300-12 at $146 with free shipping.
