Can I run a 12 volt Power Vent from the auxillary relay on the Charge Controller?
A. Yes. The auxillary relay on the Outback Charge Controllers is rated at 1/4 ampere and 12 volts (3watts). The 12 volt Power Vent is rated at 2.2 watts. Other Questions Q. Can I stack two Power Vents in a row to move more air? A. No. If you need to move more air you can use two vents, but each one must have its’ own vent pipe. You could combine the two exhausts into one larger vent. i.e. combine two 24 volt Power Vents with 2″ outputs into one 3″ vent pipe using an inverted wye. Q. Is the Power Vent Explosion proof rated? A. There is no explosion proof rating on the Power Vent. The fans are brushless dc motors using electronics to switch the fields without arcing. The cost of an explosion proof rating is prohibitive. We have done in house explosion proof testing. Please see Power Vent Testing under specifications.
