New Refrigerator?

Hi All,
I have a refrigerator that uses 392 kwh per year. I am dreaming about a bottom freezer french door beauty that uses 465 kwh per year. I have a 1500 watt system with 12 panels and 8 Rolls batteries. I am floating or absorbing most days between noon and 2pm and my system works great with the use of a back-up generator only on a fully cloudy day, and then only for a small amount of time.
My main concern is that the new refrigerator will be consuming so much additional power that I will be 'in the red' and have to use my generator significantly more than I do now.
All comments welcome.

    from what you say it may necessitate a few days more with a genny backup, but all in all i think you'll be fine. that new refrig means an extra 200wh per day being drawn. if that bothers you then get another pv to make up for it.

    That power is not too bad.

    I could not convince my wife to go with the bottom drawer freezer. She is too spoiled with the side-by-side model.

    The bottom drawer freezer has got to be much better for efficiency since it won't 'dump' a massive amount of cold air out when opened like the side-by-side does.

    The bottom drawer fridge/freezer we have, has no bottom in the drawer !

    The saving grace is that there is not a lot of residual heat in air, compared to a pint of milk

    There is one saving grace of side-by-side with front door ice dispenser. Not having to open the freezer to grab a couple of ice cubes is some consolation.
