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

[Dan Tittmann]

If you are trying to run the fan while the magnum is charging you can just
run a 12V converter run your zephyr off of the ac power supply or just get
a small ac fan.  If you are trying to run it when charging from other
sources look for the AUX relays in the charge controllers like the above
mentioned options.
