I have thought about my options going forward but power failures have been so rare here that I think I will live with what I have until I have another one. If it looks like I am starting a trend of more frequent problems I may go for something in the 7KVA neighborhood that has better voltage regulation. Fuel burn is still a concern tho so bigger is not necessarily better. I have proved I can get by with 5.5 kva but a little more would avoid nuisance trips. I found out the bladder tank on the well pump has lost some air so I was presenting locked rotor on that pump more than necessary.
