Soooo I did some shopping online for that all in one unit inverter/charger/transfer switch, and I almost fell off my couch.
800.00 for a 3000 watt pure way sine.. ouchies. And that does not include the battery pack to power the house..If I spend that kinda money, yes the inside lights will be AC. Might as well get my money's worth from the inverter
I just did the math on my insulation for spray foam, came out to around 2k. Not sure how much it would be to do it with 1" rigid, will calcuate that after work. THere is no doubt which is better insulation, but I am wondering the cost difference.
