Can I run this box fan off these solar panels? [240W Panels > 140W Fan]

Hi All!
I’m going camping in a few weeks, and have this box fan I’d love to be able to run during the day when the sun is blazing!
Originally, I thought to build a battery – charge the battery by solar panel and run the fan off the 48V battery. It turns out I won’t be able to receive the batteries in time, so I thought maybe I would be able to get decent performance out of the fan just running straight off two solar panels. I understand there is lots of energy loss converting from DC to AC comes with energy loss.
Here are the items I am hoping to use:
Solar Panels – 2 x Newpowa 120W 24V Monocrystalline Solar Panel
Inverter – KRXNY 1000W Pure Sine Wave Power Inverter 48V DC to 110V 120V AC 60HZ
Standard AC Box Fan – 1.2A 120V @ maximum
Below is the diagram for the setup I hope to achieve. I have heard that I should put some circuit breakers in between the connections.
Thank you!!
