That's true but it will run a heater for 7 or 8 hours at night which
is all you really need (assuming you can recharge in the morning).

Nope. Our Pelonus ceramic cube heater draws around 110A. With a
900AH battery bank you would be lucky to get 4 hours. Probably
less since it is drawing much more than the 20 hour rate from which
your 900AH rating is based. We have a 500AH+ bank in our mobile
canvas shop. The heater is good for about an hour.
