What’s the draw on your house batteries with everything off?
I know there’s tons of parasitic draw from appliances even when off...
Multiple tv’s, fridge, microwave, inverters, etc, etc...
Now that I’m playing with solar, trying to monitor battery usage...
With everything off... house batteries drain at 3 amps per hour!
That’s 75 amp/hour per day... with everything off!
No lights, nothing.
I was pretty surprised by that...
What do you guys get with everything off?

Never checked with everything off. Typically I'm down about 150 amps per night.

With every thing off. I think my largest amp draw is the two Propane detectors.

Plugged in with nothing on but the parasitic draws: the Bounder was around 1amp; the Phaeton fluctuated between 2 & 3 amps.

If you have your inverter turn on it will draw about 3amps. With everything off on mine, including the Main and Aux switches I draw about .1 amps.
Here is a video showing power usage with Inverter and Wally. A bonus is how to cut your power usage while boondocking... probably something you haven't thought about.

Just surprised it’s 3 amps... that’s enough to fully drain 1 AGM battery over 24 hours...

my winnie is around 1.7 - 2.1 with fridge on propane, 1 tv on stand by. Microwave clock, propane detector....
propane detect off, tv unplug, microwave unplugged... .6-1 . If I turn fridge off and put on storage mode.. drain is about gone .2 ish. probably the board in heater or water heater.... or radio in outside enterain system
All that stuff adds up when considering Solar,, that is my next adventure..
I am looking at 4 panels , that I hope can give me 30 AH per hour during the day to charge my 300AH bank.. ( 180-200 draw down max)
My use would be nominal 60-80 AH per day on occasion 100-120..
Gonna follow this adventure to learn more.. LOL

Zero draw. Disconnects remove all loads. If yours doesn't, I'd get a manual one placed at the batteries.

I think this post is about dry camping, not storing the RV, with the battery off.

Parasitic loads will be propane detector and ant appliances with a remote, like TC, satellite, etc. There is a small circuit operating that has to be on to get the signal to operate. To truly get rid of these loads, they have to be unplugged.
