I've been watching Will's videos for a while and now I'm ready to install some sort of power backup in a cabin we just bought. It will be grid charged and used for outages for now, when we aren't there - to keep the temp around 45F . When we move up there permanently in a year or two, then I will be doing solar panels as well.
Ideally I think a 20kWh (48V x 400Ah?) bank would suit my situation pretty well. My problem is I don't have relatively accurate power usage rate for the furnace. The furnace and a few LED lights could be about 40kWh/day (20,000W@240V x 2Hrs/day). Talking to the neighbors - they remember only 1 multi day outage in the past 5 years. Monthly 1-5 hour interruptions is the norm.
During an outage when we aren't there - the furnace and a few LED lights are all that would be on. When we are there, the wood stove will reduce the electrical need so much that we can live pretty comfy on 7-10 kWh/day.
Being that the cabin is in a rural area, frankly - the electricians are pretty stuck in their ways and don't seem care too much about newer technologies. So far 2 of them have said I'm crazy and propane generators are the way to go - at $15K to install.
So...
If anyone is willing to check my math I'd appreciate knowing if I'm overlooking something in my power use to storage estimates. I'd much rather spend $10K-$15K to have a battery/soon-to-be solar system installed.
PS: I'm heading up there this weekend to do some chores, so if there is anything specific that would help narrow this down - let me know and I'll get the info.
