Danfoss type refrigerator questions....
Danfoss type refrigerator questions.... We are thinking of replacing our still working ten year old Dometic 2662 with a Vitrifrigo dp2600iAc. Our trailer has 400 watts of solar and two group 24 ...

Your bank is a small-ish. It will handle 4-6A of Danfoss, but it won't last long.
Roughly, expect to use close to 10 AH per 1 cu.ft. With 8 cf fridge you are looking at 70-80 AH daily. So - Westend is right, without sun you will have 1.5 days before the bank drops to 50%. With all other loads you'll need 100-120 AH, so - closer to 1 day. Roughly. Depends on the ambient.
400W solar, in NY? You'll harvest 130 AH on an average summer day. Not on the "best" day. And you will be using about that much. This is cutting too close. Have to agree with West, adding another 100-200W is desirable. Honda will help you out, but with 600W solar and (preferably) another pair of 6V, generator won't be needed.
Adding another pair of 6V, or (more expensive) replacing your 2*6V with 3*110AH of 12V, will not only extend you stay with "no sun", but it will also give you the benefit of shallow cycle. Bank will be closer to Full at all times, so you won't need too high charging current. Solar works every day, but it doesn't always generate high amps, as you've probably noticed.
You don't have to carry all the batteries in front. If you go AGM, it can be mounted inside if you have to. They are costly, but being able to do without a generator is worth something, IMO.
