Pro Power Onboard - Overnight

[Maquis]

For 2024+ models, PPO will turn off if the truck cannot detect a load greater than ~90W for more than 10 minutes while the vehicle is off. You can work around this by keeping the truck in ACCESSORY (no brake + power button) mode or ON (brake + power button) mode, but it comes with a risk:

The vehicle is in drive-off condition.
You will have to manually turn off lights.
You will have to manually turn off climate control.
You may want to cover the displays.

It's likely an attempt by engineers to cut off parasitic losses while the truck is off, but they didn't take into consideration the fact that most PPO use cases are loads that are intermittent in nature.

"Keep on when vehicle is off" is a poorly executed feature by Ford. Tesla and GM do this much better.

The truck cannot be driven unless you leave the fob (phone if using PAAK) in the truck.

100watts cooler/warmer from Amazon

https://a.co/d/ej5xLgn

read the specs: on 58wts

What ever is written in the specs, its pulling 100watts on my truck.

90W minimum? That's insane. My whole home inverter only pulls 21W at idle. Ford engineers, good grief lol.

I suspect the 90w cutoff is due to the sensitivity of the power monitoring system. The ProPower Onboard readout says <90w any time the inverter is on and has less than a 90w load. When you have a 100w load it will read 100w. Above that it will read the load to the nearest 10w but I don't know what the accuracy and precision are on those readings.

I tested LED, CFL, and halogen bulbs up to 75w. All read <90w.
I tested a 100w incandescent bulb. It read 100w.
I tested a 120w incandescent bulb. It read 130w.

Remember that the detection circuit is always seeing the load caused by the inverter being turned on. The background draw of the inverter probably varies while it's on. The detection circuit is then watching for an increase over that background load.
