Solar Battery Charger/Maintainer Advice Needed


I have a Wolf Pup that has two 6V batteries run parallel. The spot I store my trailer at does not have electricity and I am nervous that my batteries will have a short life if they are not maintained by some sort of trickle charger.

So I read many posts about solar chargers and I am confused on what watt system I should get. I saw amazon had a "TP-Solar" 30W kit with controller. Another system I saw was a "Nature Power Solar" 110W kit.

I mainly just want the solar to keep the batteries up while in storage. I have a generator I can use while boon docking. Any suggestions would be greatly appreciated.

If you install a battery disconnect switch, you won't have to worry.
I installed one on my old HTT, right on the batteries. I could leave my trailer in storage for 4 months and the batteries were still nearly fully charged.
Never needed solar.

As Bikendan says you don't really need solar for storing your trailer.
If you want solar for storage I would get the 110 watt.
But if you do boon dock I would get a 200 watt system which would help maintain your batteries while boondocking.

Boon Docking 99% of the time.
