I am in the planning stages for a 400 sq ft off grid cabin in the central Washington mountains. Summers days are long and Sunny. Winters are short and cloudy for days.
There is no electrical grid. I want to go with a 24v system. I have been reading through the forum and still not sure whether it is beneficial to push all the solar generated electrical through an inverter and just use 120v power throughout. Or a hybrid of 12v lighting, USB power points and whatever appliances I can get. 120v, outlets around for the random plugin.
I don't have a TV or microwave. Heating will be wood or propane stove. Hot water via On-demand system. I will need a water pump to get water out of the water tank. I do have a gas generator to top off batteries to support low solar or high usage.
My main concern is the efficiency of converting DC to AC.
Would love to hear pro's and con's of all 120v or hybrid 120v/12v
Thanks,
Don Miller
