New solar project
I have a 30 foot travel trailer with plenty of space on the roof and I want to do some remote camping. I'd like to be able to run the refrigerator, watch TV through-out the day, and be able to use la...

How do you best determine your battery level charge?
What 2oldman said. Keep in mind that those voltages are for RESTED battery, i.e. 24(?) hours after the end of charging and in absence of loads. Practically, it's close enough if you measure voltage in the morning, before solar kicks in and without high-draw devices running.

Do they make a battery charge level meter?
No. There are standalone meters like Trimetric, or sometimes there is capacity-measuring feature on solar controller display, they calculate capacity from the net AH flow, but you can't rely on them. High loads will screw the readings up, not to mention directly wired inverter. The only accurate measuring is specific gravity (not applicable to AGM), or voltage at rest.
And there is also an "idiot green light" :) - green indicator on solar controllers without display. It tells you when the battery is near full. God only knows exactly when it lights up - supposedly at ~90%. I prefer seeing the voltage.
