Battery Charging ?

It is covered storage under shade (no electrical available), but adding the solar charge capability would be nice to have so I'll put that on my project list……I do have a portable 10/30/50A 12V charger and a spare 1.5A battery maintainer for the boat and other batteries. Yes…..I need to find out what load is draining my batteries. I need to learn more about convertor comments and questions. When I went to the storage facility and discovered the low batteries I noticed my panel for auto level was illuminated and there was a beeping going on!

Thanks…..this forum is so great …..I find the wisdom of experiences,PMs and feedback very useful.
