Hello all, I've been lurking on this forum for quite some time, but recently registered - mainly to ask this question! I'm looking at the larger (36/41 A) Megawatt, and am wondering what the minimu...

Hi,
All RV's will consume about 35 amp hours daily just to run the CO and propane detectors and the refrigerator. That can discharge your battery in less than 6 days, even without running lights, furnace, or anything else.
Run the generator about 1 hour per night, and you will make up about 35 amp hours. If you start at 80% full, it will not end up much fuller. However at about 50% full, 1 hour can put back about 25% of the storage capacity.
It is less expensive to install a couple of 120 watt solar panels. You can buy the panels for about $2 per rated watt at this place. SunElec.com
YOu will also need a controller, mounts, and wiring. That will not add to much to the system. A 120 watt panel will 'just keep up' with the 35 amp hour load, and never get ahead when the refrigerator is on. Yet it will keep the battery full while in storage, and that will prolong it's life many years, especially if you keep the battery full of distilled water.
Good luck!
