Relays are used in conjunction with the auxiliary output (control) circuit of many inverters and charge controllers to supply power to the battery box ventilator when the maximum output current of the auxiliary output circuit will not properly power the battery box ventilator, or whenever you would like to run the ventilator at battery voltage, or whenever you need to run multiple ventilators (for large battery banks).
- The Auxiliary Output of a FLEXMax charge controller is 200mA whereas the current draw of the Battery Vent may be 250mA., or
- The Auxiliary Output voltage of the charge controller is 12VDC, but your battery bank voltage is 24 or 48VDC., and/or
- The amount of battery bank off-gassing exceeds the 6-8 CFM flow of a single Battery Bank Ventilator and therefore multiple Ventilators must be used.
