Storage Question

[dandick66]

I had to put my coach in a storage lot for a few weeks.  Unfortunately, there is no shore power available.  At home I’ve have always had the coach plugged into a power source to keep the batteries charged.  
I was wondering if I should turn off the battery disconnect switches.  Right now I have the AGS enabled to start if the batteries drop to 12.1 volts.  I’m not sure if that’s the best solution.  I am able to check it a couple of times a week.  I just don’t know how fast the batteries will go down and if I should trust the AGS.

Dan, if it's just for a few weeks I would not worry, just let the AGS maintain the battery SOC. However, if it were to be a few months or more than I would remove the negative cable on both battery banks and let them sit providing the coach is not stored in any winter weather.

This last summer we moved and I could no longer keep our rv in the driveway at our new house so it went in storage in a neighboring state ate a place that was secure but with out an electric hook up. The house batteries are LFP so I just through the main switch to turn them off when in storage. For the Chassis Batteries I hooked up a 25 watt solar panel, bought on Amazon that that came with its on NMP 12v charge controller. When in storage I shut off the chassis battery switch and place the solar panel on the roof. Seems to work on keeping my Chassis batteries topped off.

If you are relying on the AGS be sure it put it on a run time so it will turn off after a certain period of time or it will run until you shut it off or runs out out of fuel.

Thanks for all the responses.  I put it in storage on Tuesday and I will go look at it tomorrow.  It will only be there a couple of weeks before I use it, then back in storage for a couple of weeks.  I’ll check voltage levels and generator hours tomorrow to see if it’s run yet. 
I do have the AGS set to run for 2.5 hours.

When I bought mine, I kept it in storage and turned off the battery switches every time and had no issues that way.  I did not unhook the negative cables, but that sounds like a good idea.

UPDATE 02 FEB 2022

Well, the AGS was performing as it should, but I felt the batteries were going down way too fast.  I turned the battery disconnect switches and did not see a great reduction in voltage drop over a 24 hour period.  I shut off most of the circuit breakers, but again, not a big difference.  
So, I turned ff the inverter (Magnum MS-2812) at the remote panel, and after 6 days my batteries are still at 12.2 volts.  I’ve come to the conclusion that the inverter must not be affected by the battery disconnect switches and/or I have a substantial load that I’m not aware of.

Batteries are 4 each US L16HC (430 AH) and are less than 3 years old.

Dan, I don't have a good pic of my setup, but the positives in my coach leave the battery and go straight to the battery switches.  I don't think anything else is wired straight to the batteries. That allowed me to shut off mine at the switches for a couple of months and they would be charged.  Now, though, I leave it plugged in when stored to keep the batteries maintained.
