35 ah is too high for our trailer, it has sat in the lot for 5 days or more running the fridge and detector without running our 95 Ah grp 27 down. So it is important to find out what YOUR rig uses.
The primary use of solar is as of a battery charger, but once the battery is in float the solar can be used as a micro generator to run small items or off set larger loads. On a single 24v panel we can run all of our lights, both fans and the furnace pulling 11a while the panel is capable of 16a. The battery stays in float.
It wont cover using the microwave or coffee pot but it does help the voltage under load from dropping so fast. Last year we used two panels this way and this year it'll be three. With them I can run a small 5000 BTU air conditioner and the generator will continue to stay home. It also means we have gotten away with a smaller bank too. Two panels and a 250 Ah battery can run a microwave pulling 1350w for ten minutes.
Lots of different ways to do it and lots of opinions too.
