I just check the power levels inside on the panel. They’re always fine. What am I missing?
Pretty much all of it.
Doing a search for "battery monitor" will yield a lot of threads on this already.
I use this on my Safari Trek:
$45, a deal for what it does. It can be a bit of a challenge to set up but you can always post up for help.
There are other monitors out there that are pretty trick and can tie in nicely with a new solar install but they do get a bit spendy.
The key on a battery monitor is to get one that is "shunt based". Pretty much everything else out there is not a whole lot better than the idiot lights on the factory monitor.
Boondocking/dry camping without a shunt monitor is like driving without a gas gauge and banging on the side of the tank to determine the fuel level. Yes, it can be done, but why...
