[RE-wrenches] Ferrites for EMP/solar flare protection?

[Hans Frederickson]

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
