    AC Power While Sitting at Home?

    Hi,
    We have a 2022 GD 337RLS. We are at home now and won 't go out on the road again until the end of March. Do we leave the rig plugged into house power during that period? We would typically not plug the rig in while it sat between trips until a few days before when we fired up the refrigerator. Just looking for the correct procedure.

    AC Power While Sitting at Home?

    No harm in leaving it plugged in and no harm unplugging it

    I leave mine plugged in with the fridge running from spring to fall but put the cord away in winter simply because of it being in the way for snow removal

    Leaving it plugged in will provide power to the converter/charger and keep your battery or batteries charged....which isn't a bad thing. The exception to that is if you have LiFePO batteries, you shouldn't store them fully charged for long periods of time, generally anything over a month or so. LiFePo should normally be stored between 40% to 70% SOC.

    If unplugged, and no solar to maintain your battery, disconnect it.

    To add on to this, actually disconnect the battery, don't just use the disconnect switch, it won't remove all loads from the battery.

    The LifePo batteries are lithium are they not. If your not supposed to leave them at full charge then they would not be good for someone like us that are plugged in for 7 months straight when in Florida. Is this true or am I missing something.

    You might be missing something, but then again, I may not have fully stated that this applies when in storage....as in no camper usage. If you guys are plugged in for 7 months and using or living in the camper, there would not be an issue with that. In that scenario, that battery is constantly getting discharged to some degree and the converter/charger is charging it back up.

    It's important to keep Lead Acid batteries charged...with at least a trickle charge at float voltage or even fully charged. And a Lead Acid battery will self discharge much quicker than a LiFePO (LFP) battery, so keeping them charged is a good thing. LFP, in almost all instances should not sit without some usage at fully charged, it will definitely affect battery longevity.

    When I put my camper into hibernation (winter storage) last year in Nov. I ran my LFP battery down to approx. 60% SOC. I have a battery disconnect that completely disconnects the battery from any drain.....just like lifting a battery lead from the battery terminal would do. It finally made it down to just under 34% SOC and today, I turned the disconnect on and charged it back up to 50% SOC. It will like sit like that...slowly dropping over the next few months until which time I dewinterize it this spring....sometime in April.

    Thank you for the reply. No my mistake. My first thought was being plugged in it wouldn't be getting used. Don't know why I know there are a lot of things in the trailer that are 12 volt only. They would cause it to do just what you said.

    This is the same responde that I got from Battle Born when I asked them a couple of years ago about holding their batteries at full charge all the time while living in the trailer. My lingering question is does the battery actually get discharged when living in the trailer or does the converter dominate and provide all the necessary charge and the batteries just sit there fully charged? I guess if the converter was programmed to wait until the batteries drop to a certain voltage before coming on then that would allow some discharge of the batteries. For me it does not matter since I turn off the convert and let the solar do its thing. Draw down at night and charge up in the day. The only time I use the converter is when dry camping and clouds or tree shade prevents a full battery charge from solar.

    I can say from reading my 60 day history in the Victron BMV, that there is a small but nightly discharge which doesn't always kick the charge converter on. I have a PD-9160ALV and solar so typically, solar will pop the batteries up to 14.2-14.4v which will drop back to 13.6v overnight. if the PD sees the batteries at 13.6v, it sees them as fully charged but is also sees the solar charging source. It won't kick on until 13.2v or under high amp draw.
