No Problem ! If one of our SPDs break from a nuclear EMP, just send it
back and we'll replace it !
Did you realize that if you rearrange the first two letters of the word
"nuclear", you get unclear ?

I am not seeing how ferrites can stop EMP. The frequencies
involved will affect diode junction level electronics.
Ferrites may lessen the induced surge picked up by the conductors
between the array and the inverter/charge controller, but unless
the electronics are hardened too, I don’t believe it.

Hans,
Here is a split ferrite kit (various sizes) from Mouser.com
<http://Mouser.com>:
https://www.mouser.com/ProductDetail/Laird-Performance-Materials/K-404-EMI-A-LG?qs=GedFDFLaBXEg9IWU3Su8DQ%3D%3D
<https://www.mouser.com/ProductDetail/Laird-Performance-Materials/K-404-EMI-A-LG?qs=GedFDFLaBXEg9IWU3Su8DQ==>
Sol-Ark makes an EMP hardened inverter and that kit comes with
ferrite cores for each solar panel. Both normal and EMP version
come with ferrite cores for the battery cables, Schnieder 600V
solar charge controllers comes with cores and older inverters also
came with cores. so, it seems cores are good even for regular
systems, such as to combat back EMF from larger motor loads /
inductive loads.
So, the bottom line is that is helpful to block line surges by
using ferrite cores to suppress voltage spikes & surges. And like
lightning, you can do the best that you can do and too many
parameters can guarantee anything.
I going to investigate further and make kits for my own customers.
Good luck!

Wrenches,
One of our grid-tied solar + storage customers with a
SolarEdge StorEdge / LG Chem RESU10H system found some
information online about protecting solar systems from an EMP:
Solar Power Ferrite Bundle – Practical Disaster Preparedness
for the Family (disasterpreparer.com)
<https://disasterpreparer.com/product/solar-ferrite-bundle/>
Our customer is asking for our recommendation on this. We have
used Ferrites for filtering out inverter noise but I’m not
familiar with the idea of using them for protection from EMPs.
Does anyone on this group specify or recommend these sorts of
products for that purpose? Is there any historical evidence of
EMPs being a threat to solar systems?
Thanks,
-Hans
