Can't believe you solar guys ! Like solar is the answer to everyone's problem.
Seems ya all forget that solar needs sun ! Buy a small quiet generator first, then you don't have to worry what each little thing in your rig is using.
Go camping, then you will find out how much your daily AH requirements are.
Here's a poor many battery monitor,.......
If you have the sat tv playing, and a couple lites on, and the water pump comes on, and you don't notice any noticeable lite dimming, or the sat tv skippin a beat, you are well over 50% yet, and good till morning.
I couldn't care less what each dc item is drawing, I just care how often I need to recharge !
And I dint just start dry campin yesterday.
But yep, I got ammeters and voltmeters all over the place, but I know how often I need to recharge, and that doesn't change by much.
And yep, my solar works fine, when the sun is shining, but that hasn't happened in a week now.
