    Interesting solar observation, at least to me.

    I left my RV setting in storage with the 12v Disconnect on, so a few things would draw power, but no lights, or any appliance. Maybe the smoke detector and Propane detector. Even leaving the RV along for a week in the sun, I see the command center battery meter says full, but the solar controller never shows float mode. So I guess there is enough background 12v usage to keep it out of float mode.

    Today, I disconnected the 12v Disconnect switch and an hour later the controller showed float mode. So there is a lot of 12v stuff that is powered even though you don't think about them.

    Jim you are right about the draw. The level up draws about a 1/2 amp even when turned off even if the disconnect switch is off. The roof fan control unit draws about .3 amps.

      Now that we are in Summer, I have two fans running all the time on low. I see about 40 to 44 AH used when the Sun goes down.

        This seems like a lot for just keeping a circuit board active. I assume nothing is actually working - just phantom draw???

          I have 2.3 amp draw with nothing on. With the battery switch to off I still showed 1/2 amp draw and when I pulled the fuse to the level up it went away. There are 3 different circuit boards on the level up that I know of.
