Just Starting Solar Research
Man, there's a lot to read and digest with possibly installing a small solar panel. I very recently replaced my original 1-stage converter/charger with the Progressive Dynamics PD4600 series conve...

As noted, voltage shows approximate State Of Charge only when battery is at rest, and even then it is recommended to give it 24 hours rest to get an accurate SOC reading.

True for the most part. But that is very impractical while actually using the batteries, and that is when you need SOC info the worst !
The good news is that once you are experienced w/ your system, and w/ your habits of battery use, you can use your voltmeter to quite accurately tell you when its time to recharge.
I have a 2nd digital LED voltmeter mounted in the cabinet right at the tv, visible day or nite. I am seeing the voltage constantly while watching tv. w/ a given (always the same) load, which is the tv, the satalite receiver, and one light on. If the volt meter ever goes below 11.0, I know its time to recharge.
11.0 volts is correct for my system, includes voltage drop thru a long wired circuit etc. The voltage may be somewhat different for your system, and your habits.
