What is the best set up to keep my Sprinter battery charged while off grid? It has an electric sliding door which runs the battery down after a few days of not travelling and I'm trying to avoid starting the motor to charge via alternator. Thanks

I have no idea what size battery you are talking about but if it is going flat after a couple of days then either your battery is dying or you have a parasitic current drawing power.

All that aside, for my boat which has a 120ah AGM battery I have a 30W solar panel and a mini solar controller.

Normally I would not recommend Ebay panels but as the output isnt critical that is where I bought mine.

Some people do not bother with the controller.  Jaycar have them or you can buy them online.
