I certainly watch my DC METER PANEL like a hawk when camping off the power grid. When my battery banks drops to around 12.0VDC I need to startup re-charging procedures. I have planned out my daily and nightly D Power drains for this to occur at 8AM each morning so I start up re-charge procedures during breakfast each morning. Then I can do all of this all over again for the next day/night run from the batteries.
My Homemade DC METER PANEL is installed in a good spot inside my trailer where I can observe the DC VOLTAGE of both my switched Battery banks as well as how much DC Current is being drawn from the selected batteries under load. I can also see how much DC current the selected batteries are demanding from the on board converter/charger unit when being charged.
This is where I tied my DC meter panel into my battery setup at the main battery bank selector switch...
If you are planning on camping off the power grid this is a must have item to have.
OOPS I just noticed I have already posted comments on this already. At least i said about the same thing in my two posts. haven't had my second cup of morning coffee yet hehe...
