Solar Charge Controller

I will be fine with that little 12 volt meter. I usually check my voltage at night, bed time. We use such a small amount of 12 volt that we have actually went out and set up and stayed 2 to 3 days and never get any sun for the solar panel or run the generator and we still have plenty of power left in the batteries. When it is like that it is easy to measure because it starts out high and just keeps getting lower and lower, no guess work is needed. Last time we went out one of my batteries had a bad ground connection and was not even in the circle and we still had plenty of power with the single battery.
