310 RL Battery Life and Storing procedure

[Kingsize]

I have a 2025 Alliance Paradigm 310RL. I am confused as to how to store the unit to preserve battery life. When we first bought it and stored it, we turned the solar and battery off when we parked it in our covered storage. When we went back the battery was dead.

When we parked it the next time, we left the solar on but turned the battery off in our covered storage and when we came back a couple weeks later, the battery was dead.

I am trying to determine the best way to store it and it seems it might be to just remove the cables from the battery but they arent near as accesible being behind a door and in a battery box. Any help is appreciated.

Also, we just got it in march and have not tried dry camping in it. Does anybody have any idea how long the solar will support the trailer off grid with just the fridge running

1 - You will need to add a true battery disconnect switch to easily cut all power. I am guessing your 12v frig was still pulling power, when you were in storage...unless you used the power button on frig to turn it off. Frig will pull about 7 amps per hour, while running. They cycle on and off during the day, but I estimate they use about 75-85 amp hours per day.

2 - Not sure how much solar you have, but a typically if the panels have direct line of sight to the sky (and summer time) you will see about 5 amps of charge per hour from a 100 watt panel. There are many factors that can make this vary, but 5 is a safe number for each 100 watts of solar

frig is always turned off when stored as area all lights and other possible draws. The trlr has a battery disconnect switch but I think it may not be a true disconnect. Not really sure how that could be. Seems disconnected is disconnected but like i said if i turn it off you would think the frig would have no power. Somehow the battery is still dead. Thank you for the information. It is helpful. Do you think because the storage is covered it causes the solar to not receive enough light to charge at all? I am wondering if the solar management id what is running the battery down because if gets too little light to do any charging. Then i think how can the solar operate if the battery is turned off?

I noticed on our 310rl that the Renogy controller was still on even with both the “master” and solar disconnect switches off. When I disconnected the battery cables the Renogy finally went dead. Not sure how much power it draws, but it’s something.

I think there are a few things going on here. First, the battery disconnect won't shut off all power for a reason. If you were to turn off the battery and then forget to turn it back on, you would not have emergency brakes if the RV was ever detached from truck. Granted that is a lot of problems that all need to line up, but it could happen, so MFG have to wire it as such.

I also think the frig is seperate, so you can leave the power "off" to everything, but still have the frig running to keep food safe. This is just me guessing...I have no real/confirmed reason for this.

@Kingsize Yea, you need sunlight to have solar working. If it is under a cover, but light still hit it, it most likley is not enough voltage to turn on the MPPT controller. Most MPPT controllers require ~20 volts to actaully start producing outbound power.
