solar options
Last summer I had a 240 watt kit(from Solar Blvd.) Installed on our MH. It has two 120 watt panels feeding a 20 amp charge controller. I recently had the two stock 12 volt marine house batteries rep...

I would not want 14.5 volts on my battery for two hours every day when not in use.
This is where the Morningstar (and others) can be programmed to charge differently depending on the start voltage each day. While in use you may want four+ hours at 14.2/14.8 and not in use just 15 minutes.
Storage is different from camping for sure. Adjustable voltage is good so you can also set to a Float like 13.4 when in storage and crank it back up to 14.8 for camping.
It also depends on the charging profile of the controller as to what it does once it hits the 14.5. Some have a timer that holds it there for say two hours. Some stay there till it gets dark which could be another six hours. Some stop charging right away and let the battery voltage fall to 13.x (low set point) and then start charging again till it reaches the high set point again. I think most solar float chargers do that up and down thing.
