I have so much excess generation, I can do whatever. Now we shall see if thats too cold for her, if so we will try 76. And since I run off batteries 100% after 30, and basically all solar before, I prepaid for all this furn My wife wants it cold. So next winter, rather than my 60 degree, want to do 66 or 68. For 30 years never could do any of this, house to big and expensive. But with solar (any maybe more), and batteries, I can do ANYTHING!!!!
