Hi Mike,
How many amp-hours is the battery bank?
5 days @ 37 amp-hours per day = 185 amp-hours. To stay above 50% state of charge the battery bank needs to be in the 400 amp-hour range. That's four group 29 or four golf cart batteries.
Then there is the issue of recharging on the weekend. A good three stage converter is going to be needed.
The other way to go, if the battery bank is small is 150 watts of solar per 100 amp-hours of storage capacity.
