Hi,
I have a 415 watt solar system, and am lucky to see a full set of batteries if I start the day at -120 amp hours. I also have a "E-Meter" that carefully measures the amps going in and out of the battery bank. So I don't think that 400 watts will produce much more than 100 AH daily more than what the RV is using. CO and propane meters also consume about 0.8 amps per hour, or about 20 AH daily.
Lights and such are on top of that.
I have heard that Samsung has a good refrigerator for full timing that actually is a DC powered 120 volt refrigerator, and will work best at full timing.
Also my 1500 watt MSW inverter is less efficient than my 150 W MSW inverter. So normally when running the TV, I shut off the 1500W inverter and use the 150W one. It draws about 6 amps total with the 150 watt, while the 1500 is drawing about 8 amps - this while watching Direct TV and using a 19" tube type of TV set.
SunElec.comTHey sell reasonable priced solar panels.
Fred.
