If you dry camp most of the time would 2 6 volt batteries(220 AHS) and 2 hrs of generator time per day be enough to run a residential refer? Or would you really need 2 more batteries just to supply voltage to the refer and solar to keep the batteries charged?
My 10.7 resi pulls 8 amps and uses 30 Amp Hours overnight and that includes .5 amp of inverter draw so a 24 hour number is about 70 AH. From there you would need to add up all the amp draws of other devices and the amount of time they are used to get your other additional amp draws.
This could turn into a book if I go on. You need to figure out your total energy use. If you were to give us a sort of list of all the stuff you want to run we can give you more input.
Where will you be while solar powered? Yuma or far north?
Do you use the house furnace?
How big of Television, lcd or led?
LED lights?
Laptops, how many hours?
Vent fans, hours.
There is no one size fits all. Some run a generator for part of their early charging because generators and good converters do well at socking the big amps in during bulk charging. Solar can then take over as the sun rises and do the slower finish charging.
You know I read all these residential refer threads because my Norcold is 21 years old and ask my self if it goes would I replace it with a residential. I dry camp 95% of the time in NFS CG's that are heavily shaded, have minimal electrical reqs(a few lights and water pump no TV, radios etc. My 2 6V GC batteries last 7 days before reaching 50% SOC, so to me solar never made sense. I look for ways to run my genset so I just don't have to exercise it each month. My friend has a residential in his newer Tiffin DP and when we dry camp he has 4 6v GC batteries and the genset runs for at least 2 hrs a day. From reading previous threads I concluded that I would need 2 more batteries to run the refer plus at least 2 hrs of genset time each day.
