On the roof we've got 15 220w (3.3kW) Sanyo panels, feeding 24 2v Surette 1380 (1075ah) batteries for a 48v system. The charge controller and inverter are Xantrex XW series with a Xantrex power distribution panel.
With heavy use (over 50% drain) the batteries are supposed to be good for 8 to 10 years. We have all LEDs for lighting and all Energy Star appliances. Our heat pump is a Daikin 1.5 ton mini-split. Even in the worst of the Summer heat, battery voltage never dropped below 50v, so we may get 10 to 12 years out of them.
We have all the regular appliances except an upright freezer. We wanted to see how things went for a year just in case we needed to go to a propane one. It looks like a regular freezer will be fine.
My only unusual chore is topping off the water tank once a week. And I may be able to do away with that soon.
