Shrapnel hit it on the nut...mb
Been looking into that also for our place Paul... people locally who I know, "who are in the know", pretty much are saying exactly what Shrapnel is saying. I'll try and get a friend, whose home and (property that has 7 Cabins on it, rented full time), to take a look at the thread. I know power outages doesn't affect his place at all., and its rural.
He has 2 or 3 Generac Units on his property. Paul is also a qualified electrician, so he installed them all...
If I can get this in front of my friend Paul, will report back via PM.
This is on my list also... but for just my our property.
