Residential Refridgerator
I have been thinking about putting a residential unit in our rear kitchen fifth wheel trailer. Most that I have seen have shelves that just sit on the side supports. Might they be always be bouncing o...

Gdetrailer - there has been many changes and upgrades to Mr Wiz solar system, and in the end I don't know how well it performs. One thing is clear - adding 60-70 AH daily load - like replacing LP frig with 120V frig - without adding some power source can not result in a shorter generator time. Achieving this would mean inventing a perpetuum mobile machine and I will be the first one to congratulate such a person :)
When you take 60 AH out of the battery - make it 70 AH after inverter - you need to put 80-85 AH back into battery. To put 80 AH into battery, you need to run 2000W generator for 1-1.5 hours, maybe 2-2.5 hours, depending on the battery SOC and other loads running. There is no free lunch in energy use - when you use more, you need to get it somewhere.
To meet these increased energy needs without increasing the generator time, you need at least 350W flat solar panel. Increasing the battery bank will help very little.
You DIDN'T READ my post. 62Ahr in MY CASE INCLUDES the inverter losses FOR 24 HRS.
And once again NOT EVERYONE takes 60" big screens with 1000W surround sounds watching 10hrs of TV per day plus 3 or 4 laptops along with a few cell phones AND BOONDOCKS.
I can't figure out just how folks use so much battery and have to spend half the day charging boat loads of batteries.
In my case only a few hrs charging time every 12hrs works perfect, once in the morning and once in the evening..
In my case 30 Ahr so every 12 hrs is not bad at all.
