Tony,
Thanks for the update.
Does anyone know if there are issues using clamp-on ferrites exposed to the
weather?
I'm concerned about the Ferrite material characteristics changing with moisture
ingress, damage caused by ice and UV damage of the ferrite and plastic clamp.
Tony, you may want to ask the Solar Edge engineers about these concerns.
I always enclose my ferrites in an enclosure.
