[RE-wrenches] To insulate a battery bank DEPENDS on a lot of factors.

[Nathan Jones]

Wrenches,
Thanks for all the input on insulated vs. non insulated battery banks. I was setting up my 48VDC HUPS at my new off grid home when the thread started and read all posts with interest. Two weeks past and I feel much better educated about this subject, but ironically still don't know whether to insulate or not insulate. Both sides have valid points. I noted with interest that Rob at NWES and James at Surrette did not weigh in. Maybe preferring to let us hash it out among ourselves, but also perhaps because there is no one answer.
At any rate, thanks to all for many solid cases made both for and against insulating batteries.

Hi Dana,
The manufacturers that I've read, do say they should be in a vented enclosure.But your point is taken,
thanks,
jay

Sealed batteries do not require a vent , therefore no air passage – less influence of ambient exterior temps to the bank. Perhaps on a small bank this would have an influence.On a large bank in a low usage scenario, IE: second home with no one home, the system may be full by 10AM and the fan runs for most of the day inducing cool air.  Granted most systems have a present [physically] home owner. I have many systems that float for a good part of the winter, awaiting the arrival of either the owner for a week or spring.
