Running a/c on batteries
You guys are actually way off.
: )
The window unit runs on 3.5 amps at 120 VAC.
But when you run any AC device off an inverter using a DC power source (batteries) you multiply by 10.
This unit requires 35 amps to run off my battery bank through the inverter.
I was also running my Weboost and WiFi router, which together draw 3 amps, so let's just ignore those 3 amps for now, and focus on the 35 amps that was being "inverted" for the window unit.
35 amps x 12 volts = 420 watts
The roof air which is 15,000 BTU requires 15 amps on 120 VAC or 150 amps running on an inverter.
So the window unit only requires about one FOURTH the power. It’s also much quieter.
: )
I posted a video showing this information here:

Resistance is Not Futile, It's Voltage Divided by Current.

Running a/c on batteries
I see, so no technical reason just a recommendation.
Same reason I have the same inverter.
But now I kinda wish I had done my own research, I might have gone with the Victron instead. I am learning to appreciate the Bluetooth display it has.
Are you planning on running air conditioning off your solar?
