Wrenches, 
I'm planning my first off-grid install since the late '90s and I know a 
lot has changed both equipment wise and with the NEC. 
I thought that since a 48V system was considered being able to operate 
at above 50V so was considered not low voltage. Now the NEC refers to 
(24) 2V cells the same as a 12 or 24 V system. Is there no difference in 
the equipment, disconnect rating, ampacities, sizing etc?
Also what are some examples of 690.71 "Non-load break bolted or plug in 
disconnects..." in the battery container? 
Thanks as always
