[RE-wrenches] 24V Zephyr Vent Fan from a Magnum MS4024PAE inverter

[Mac Lewis]

Yes, with the 24V fan, you will need to run battery power (or another 24VDC
source) through the contacts.  That's the reason I opt for 12V vent fans
typically, so they can be served with the 12VDC Aux source from the charge
controller.
