Ah yeah that makes sense. What gauge wire Is used to connect directly to the battery? So many choices on Amazon, if you are happy with what you got, which one is it?

Also, if the 12V battery is an AGM I guess that would work better this way than a typical starting battery, but what would I have to do to keep the 12V charged while using the inverter? Sounds like something that could be a good solution... Thanks!

I went with this inverter and 2 AWG cabling.
