“ Beware of your solar amps, might have to switch off solar.”
True enough (i.e. unheated batt compartment), but bear in mind a ‘sweet spot’...
Let’s assume a real-world correlation regarding inclement weather and reduced harvest amps - for the broader audience, lets say somewhere within the vicinity of the 40th’ish parallel...
My sweet spot experience having 200a/hrs of LFP and 440w (Max rated) of solar, I’ve yet to see a single episode when solar amperage neared an unacceptable level - often where even a much reduced harvest-charge rate might be acceptable (or easy to manage) to as low as even 25f.
With appropriate component sizing (batts, and solar) this consideration can often be a relatively self-tending matter, or at least relatively easy to manage... Having a parallel solar set-up (panel count roughly divided between two separate switchable controllers), can also help.
