General RV Solar Questions?

Hi Jim,
That is the reason for using a temperature sensor on the battery bank. It is true that solar harvest will be lower in the winter. But then, most RV's are snug as a bug in a rug (in storage)--and the solar will easily keep the battery bank full.

When a larger battery bank gets down, it takes either a lot of panel to push it around or days to recharge it. I ran a test with a 250ah 8-D discharged to 12.1v resting and a 220w system. After 5 hours in brilliant sunshine and subfreezing temperatures I think it made the battery giggle. The battery needed 125 ah replaced and the system could do a tenth of that, it would take days. Even tracking the sun for long hours in the summer, it would take a few days to get a really good charge and that's without you using it.
Simply put, big loads take big battery banks, big banks need a lot of panel.
