Re battery Ah – based on what I read, 200 Ah is minimum I should go with. I would like to have a comfort not to worry whether or not the battery will be drained too much in the morning, or to be able to use powerful vents will be napping, thus 300 Ah… however, I am always planning to use things for a longer period of time… kids will be growing, more power needed, so I am considering 400 Ah
Beside, batteries less drained, they will last for more cycles…
