    I finally sat down and watched your install videos. Great job. Gave me a bunch of ideas on how to improve my little system. In other searches I found a guy that put his batteries under his entry stairs. That might help me with my space issues for additional capacity. I can only hope my system approaches yours in detail and efficiency. Very well done.

    Thinking outside the box on batteries might be a good solution, but be aware of venting.

    Fumes given off by a charging battery can be explosive and corrosive. I believe the fumes are heavier than air. There are battery boxes with a vent tube and small fan made for sailboat solar systems, but I bet you could come up with an exterior area to which a battery tray could be added.

    Also, obviously be sure any positive cable is well protected from chaffing or getting pinched, or otherwise shorting to the frame.

    That only applies to flooded electrolyte type batteries. AGMs and lithiums don't vent and don't use vent tubes. Flooded type batteries are almost obsolete today. AGMs are available in almost all sizes and configureations, even the big group 31s.

    Good point.

    Flooded cells are still pretty popular as RV deep cycles and other solar systems, because they give the most amp hours stored per $ when you look at capacity, expected life, and price.

    If you have to mount batteries in the living area, or in an area where checking water level is difficult, AGM could be worth the extra price.

    I run 2 6v-volt golf cart batteries wired in series. They have as much power as 3 of the biggest 12 volt deep cycle batteries. I never got more than 3 years out of a 12 volt deep cycle. I got 12 years from my last golf cart batteries. I just plug the trailer in for a few days once a month when I am not using it.
