At home I keep them both on. I actually never shut off my RV including the fridge
. There is nothing I believe in the fridge
that wears and I believe that keeping the fluids moving may be beneficial. If any one else knows otherwise please respond.
As to simultaneously running both the Solar Panel
and the Convertor, my thinking is that the converter will go into it's smart cycle and work to desulfate the battery
no matter what the Solar Panels are doing, though the solar panels can reach desulfating voltages.
I'll be interested in other's views
