Topic: Newbie to rving and need storage advice (Read 1614 times) previous topic - next topic

We just bought a 2022 ltv unity mb with lithium batteries and 400 watt solar on the roof. We need to store it for about 5 months and we are not sure what the house and chassis batteries require. We are in Florida so no worry about freezing. Do i need to keep it plugged in?  Power knob off? Chassis batteries same as house?  Any guidance would be great

with solar all you need to do for the house batteries is turn the Main Power off
for the chassis battery - there is a "Battery Isolation cable" which you can find in the MB manual.  It is located beside the gas pedal. and there might be Fuse #32 that needs to be pulled out.  No trickle charger needed.
If you do not have a manual you can get one from Owner Manuals | Mercedes-Benz Vans
Battery Isolation cable disconnect is the same has pulling the negative wire on the battery.  After you have turned the engine off and pulled the key you need to wait 20+ seconds before pulling the diconnect cable as that will save all the computer settings

Thank you!  I have been reading reading reading and your reply makes it so clear.

I have no issue with the above advice, but you didn't say whether the RV would be stored covered or outdoors. If outdoors, the solar charging would keep your house batteries charged. In my case, when I stored outside over the winter I left the 12V house side switched on so my Winegard hotspot remained active. I like being able to remotely monitor inside temp and I use a wifi camera to visually be able to check on things.
Also note the if you want to monitor the chassis stuff through the Mercedes app, you loose that capability by disconnecting the chassis battery ground.
In my case, I had a AMP-L-Start B-2-B battery charger so I could also top-up the chassis battery from when the house batteries got charged via solar.

Oooooo more to consider. It will be stored in central Florida so no freezing to worry about and only in winter so i will keep an eye on the temp but should be ok.  Losing the Mercedes App would not be good. I will have to consider the ease of just disconnecting vs adding a trickle charger. Thank you for that option
