[RE-wrenches] Solar vent for flat roof

[Allan Sindelar]

We have twice used pairs of Zephyr Power Vents to successfully vent large
banks, up to around 2200A/hr @48V. A 12V unit exits roof or wall with a 2"
pvc stack; 48V is 3"; thus they flash just like standard plumbing vents.

Note that the charge rate is more important than battery capacity, as it
determines the amount of gassing that must be exhausted.

Wrenches,
Our client has 48 IBE 85N-15 batteries in a room with a flat roof. What is 
your recommendation for a solar powered vent that works well and flashes 
well so that it does not leak? Thanks in advance for your advice.
