Fans?
If I wanted to install a couple of small 12v fans by inverters for a little more ventilation, what fan should I use that draw a small amount of power,and blow well . I could connect to a thermal switch so they only run over 90 or 100 degrees?

Art,
This is what I use with a digital thermostat set on 100 degrees.

Tom and I disagree on this. I want my inverter fans running 100% of the time. The cooler the inverters are the healthier they will be. The fan he showed is what I have and the only time I can hear it is when I enter my garage and there are no other noises I can detect the quiet hum of my inverter compartment fan keeping my inverter happy.
I think the fan noise interferes with his hearing aids and the phone app he has to adjust them.

Do you mount fans on the outside of the inverter any pictures? If I mounted one 12v fan on the left side of each inverter and have a 100 degree thermostatic or can a fan run 24/7 ? on left is the vent that lets air in from the internal fan.

As you can see ole grouchy and I disagree on the fan deal. My Marathon came with 2 bay fans, intake and exhaust, controlled with a snap disc. I had to replace both fans and went back with a digital thermostat. Liberty’s have the bay fans as well, but they run full time. Further, my 01 Liberty bay fans were hard wired to the inverters. Maybe there was only one, I don’t remember.
Why would you want to have cooling fans running constantly during cool or cold weather?

Art, I’ll whisper this so the old guy with hearing aids doesn’t hear me. First, your inverters have fans inside the enclosure and they are thermostatically controlled by the inverter. Not only should they run as the inverter temp rises and calls for cooling air flow, but you need the air they pull through the inverter to be cool which is why an inverter in an enclosed space needs to bring in fresh cool air.
So your inverters can be ducted so the internal fans draw in air from an outside source. Or you can just insure their location is kept cool so as they draw air into their location it is cool.
Since Tom asked why you would bring in outside air when the inverter compartment is cold, he is correct, but my concern is since his old bones cannot handle cold weather and his bus never sees temps lower than 22C ( did that to force him to figure out how that is in real degrees) why not run the fan all the time so the inverters don’t have to sweat in the 100 degrees his thermostat is set at.
Since we are whispering, he is correct in that you can use a thermostatic control, but the how do you know the inverters are getting sufficient cool air if you don’t hear that fan running all the time? What if the thermostat or fan fails? Will you think it has just cycled off?
