The Power Vent provides positive venting of hydrogen gas from the battery box. The built-in back draft damper stops cold outside air from entering the battery box. The Power Vent can be easily installed in a PVC pipe battery box vent system. Many inverters and charge controllers have a relay system that can power the Power Vent. Available in 12V, 24V, and 48V.
Note: A controller is usually used in the circuit to cycle the fan. OutBack inverters and charge controllers may have a 12-volt powered auxiliary relay available. Other inverters may or may not have a voltage controlled auxiliary relay. Please refer to the appropriate manual for hook up and programming instructions of these battery box vents.
