For many years I have had these questions asked of me -
Should you or should you not insulate a battery bank in an Un heated building? If the battery bank is giving off enough heat to retain is the system being operated correctly to produce that much heat? If it is giving of that much heat the vent fan will be on therefore cooling the battery bank. If the battery is cold and the building [say in spring] warms up the insulation will prevent the bank from warming with the ambient temperature. Should it be a little insulation say 1" or 2-4" of insulation? I have leaned toward an insulated building with a vented battery box as required by NEC and Colorado electrical inspectors. I have worked on battery banks installed by others that are super insulated with convection venting and found them to be very cold. Colder than ambient temps.
