Wrenches,
I'm looking at a potential battery backup system wtih a 200 AH @48V flooded
battery bank in the basement electrical room of a 3 story building. There is a
window in the electrical room. The batteries will be located about 10' from an
outdoor wall. The building is all reinforced concrete, so I can not run a vent
pipe vertically from the batteries. Does anyone have a rule of thumb for how
much the vent pipes can be angled from the batteries? Would it be more lenient
for short sections of pipe (say <2') versus one long angled piece from the
batteries? My instinct would be to keep the pipe no more than 45˚ from plumb.
Or with bending the vent pipe: does anyone have a best-practice rule for the
sum of the angles of bends?
Thanks,

Subject: [RE-wrenches] Pole Mount PVC
Hello Wrenches,
With pole mount systems, It looks cleaner and is safer to run the PVC
conduit down the pole into the concrete, and use a 90 degree elbow to
come out through the side of the anchor underground. This way, the
pipe is protected from mechanical damage, and there is nothing to trip
over when adjusting the array for seasonal tilt.
I was told that some building departments will not allow this. Has
anyone had a problem with using this method, either technical or
legal? How do you like to route your conduits?
Thank you,
Drake
