By running the load through the Morningstar, this one;
I'm able to determine current draw for each and every item I've got in the camper. I can determine battery charge capacity by monitoring the charge input and track it to the load output so I can have a good idea of the percent of charge left in my battery.
I know, for example, that my heater's fan draws 3amps on low speed and 5 on high, the current draw of my LED lights, etc. This came in handy when I saw a draw of .5amps but nothing was on. I discovered I had a rechargeable flashlight plugged in that it's battery was going bad and would not charge up fully. I also knew when one of my jack motors was needing service as it was drawing a few amps more than normal.
If you look closely at this controller, you'll see a button that can shed either the solar panels, or the load. Push the button once and all the load is off. Just like the emergency cut-off switch built into the camper but handier.
I'm sure most folks don't care to know that much about what's going on in the camper, but it's sort of a hobby with me.
