RFI precautions in MN15-12KW-AIO ALL IN ONE ?

Someone is building a home near me and is considering a solar system using the MN15-12KW-AIO ALL IN ONE inverter.  Does this inverter include any devices to eliminate radio frequency interference in the 3-30 MHz range?  Or, does the installer receive information from Midnite to address such a problem, or is it left entirely up to the installer?

Are you asking if the near by new install is going to give you RFI at  your residence ?
Or is the person installing wondering if the MN-15 is going to cause RFI at their own home ?
Someone must be a ham radio operator .
I don't know how the MN-15 is since I don't have one , but in general I think most hams would use  ferrite on all the cables going in and out of a controller or inverter to help with RFI issues. There have been past discussions on the forums here about that regarding other controllers or inverters.

I am the ham operator.  I'm looking for anyone who has knowledge of a system using the MN15-12KW-AIO ALL IN ONE inverter and knows about the RFI potential of this device.  I'm particularly interested in RFI in the 1.8 to 30 MHz spectrum.  All such devices have the potential to generate RFI but manufacturers have not provided any information that I've found that rates the emission levels from the inverters.  Possibly because it depends upon current being delivered and other variable factors.  I know all about using ferrite toroids and have seen recommendations regarding their placement.  But I also know that the ferrites are a mechanism for reducing the RFI level and do not totally eliminating it.  Some inverters produce less RFI than others.  It may be that properly installed ferrites will bring the RFI level of this inverter down to a level where it's not a problem.  Or, maybe not.  I've had my own small solar systems for powering my radios and went through the process of finding a "quiet" charge controller that didn't generate RFI.

The MN15 comes with ferrites for the ground and battery lines. I have one up and running and have not noticed any interference in the 2M band.

Generally speaking Midnite has been better than most about RF interference with their products. I would expect you'll be fine, but have not tried other ham radio bands to confirm.

Interesting that it comes with ferrites.  I wouldn't expect to see much of a problem on 2 meters, but the HF bands are quite another story.  Right now it appears the system will be up and running in the late spring so I'll know more then.

@FSense - sorry for the thread necromancy, but what did you find out?  How noisy is this thing on HF?  Thinking of putting in an AIO stack across the room from my radio rack and would very much not like to deafen my station.
