In my way of thinking SOLAR and BATTERIES go hand in hand... SOLAR ENERGY for me would only be usable when in the high SUN so any power that is obtained from the SOLAR PANELs should be captured by the trailer batteries so that I can use it.
You might find a few things to use only when the SUN is high but I really haven't found many things that would benefit me doing that...
I would want to store the captured SUN ENERGY in my batteries to use when I needed it...
Hopefully the SUN ENERGY will do a complete battery charge for you during the high SUN DAY... The SOLAR PANEL Controller should be a smart mode unit that will re-charge your batteries just like when you are on SHORE POWER and not do any harm to your batteries like over-charging or boiling out your battery fluids etc... The SOLAR PANEL Controller should produce the 14.4VDC-13.6VDC-13.2VDC charging modes when the on-board batteries demand it.
Like said in the posts above all solar panel cables should be protected by high current fuses so that short circuits will blow the fuse and protect your system when left unattended just like it does when on shore power.
