I'm not an EMP expert by any means, but I've dealt with quite a few
lightning damaged systems. Having a good connection to a low impedance
grounding system (steel cased well, Ufer ground) is crucial. I also
have had fantastic luck with Midnite's MNSPD line. Delta, not so much.

Right Dave. The VooDoo of EMI filtering, lightning protection or EMP
induced voltage reduction attempts are similar and governed by the
inverse square law. How much energy and how close is it? You must
properly reduce energy propagation _at every point._ I have seen very
expensive protection systems with poor implementation making the
entire scheme useless. So, is the cost and effort worth the results?
Study, then study more. It may be more cost effective to have a back
part rather than spending money on an expensive preventative measure.

Depends on how close and how strong the pulse or strike is. In Mil
satellites, the same thing. You can harden but are dreaming if you
think your electronics can really survive it. Even harder to
protect electronics that are powered on. The KH series spy sats I
saw schematics for had redundant systems that were off or rotated
I seem to remember. This was back in the 90's so very sketchy in
the fog of time.
For Offgrid, and High Rel power systems, a faraday cage for your
inverter and CC is a must if you are in high lightning zone. A top
of a mountain is often really hard on a house or Telcom. One place
I have blows SPD's yearly.

Backwoods Solar sells kits to harden against EMP. I am wondering
how effective they would be.

I would review Sol Arks website as they say they are immune.
Probably have something to back that up published there.

Aloha all,
Have any of you come across any articles or white papers on
how PV systems (including energy storage) fare under
conditions of electromagnetic pulses and solar flares?
Mahalo,
marco
