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

[Drake]

I recommend using the AUX relays to trigger a 
separate relay which will pass current from the 
DC source to the fan. In this case you would want 
to use a 24 V vent fan. With this system,  the 
higher the voltage the faster the fan. The AUX 
relay will never be subject to overcurrent, and the fan will be more powerful.
