Doubt about Solar Panels and the Lithium Battery

[Sid]

Hi,

We just bought our first Montana. 2022 Montana HC 335BH.

It came with a solar panel and a lithium battery. We had other trailers in the past, but never with this setup. The Solar controller is a Victron MPPT 75 / 15.

While keeping at the storage, should I turn the battery Off ? I m leaving On during the summer because the panels keeping the battery charged.

And, as I live in Colorado, should I remove this lithium battery from the trailer during the winter?

Thanks for your support.
