MPP All-in-one and BMS low temperature charge protection

[BlueFox]

Apologies if this has already been answered, I spent some time searching around and couldn't find a similar question.

Say I'm running an MPP all-in-one (3kw model or around there) in an RV setup.

It's charging from solar or shore power, the batteries fall below the freeze point, and the BMS opens the charging MOSFETs.

What happens? Does the MPP unit deal with that in a clean way when it suddenly sees essentially an open circuit on the battery, or does it error out and require manual intervention once the battery is back above freezing?

Thanks all!
